Abstract
The Common Information Model (CIM) [1] is an object-oriented information model 
defined by the Distributed Management Task Force (DMTF) which provides a 
conceptual framework for describing management data.
The Hypertext Transfer Protocol (HTTP) [6,7,10] is an application-level protocol 
for distributed, collaborative, hypermedia information systems.  It is a generic 
stateless protocol which can be used for many tasks through extension  of its 
request methods, error codes and headers.
The Extensible Markup Language (XML) [3] is a simplified subset of SGML that 
offers powerful and extensible data modeling capabilities. An XML Document is a 
collection of data represented in XML. An XML Schema is a grammar that describes 
the structure of an XML Document. 
This document defines a mapping of CIM Operations onto HTTP that allows 
implementations of CIM to interoperate in an open, standardized manner.  It 
utilizes the CIM XML DTD [2,11] that defines the XML Schema for CIM objects and 
messages.

1. Introduction
This document defines a mapping of CIM operations onto HTTP that allows 
implementations of CIM to operate in an open, standardized manner. It also 
defines the notion of conformance in the context of this mapping, and describes 
what behavior an implementation of CIM must exhibit in order to be described as 
a conforming CIM implementation.
The remainder of this document is structured as follows.
  Section 2 describes the CIM Operations which form the HTTP payload, using XML. 
  It specifies the syntax and semantics of the operation requests and their 
  corresponding responses. 
  Section 3 describes the encapsulation of these messages in HTTP request and 
  response messages, with examples of each. It describes the extension headers 
  used to convey additional CIM-specific semantics in the HTTP Header. 
  Section 4 describes in more detail other aspects of the encapsulation: 
    HTTP Version Support 
    The use of standard HTTP Headers 
    HTTP Error codes 
    Security Considerations

1.1. Requirements
There are potentially many different ways in which CIM operations could be 
represented within XML, and those operations encapsulated within HTTP messages. 
In the interests of interoperability between different implementations of CIM 
there is an obvious requirement for standardization of both the XML 
representation and the HTTP encapsulation. The XML representation is defined in 
[2,11].  This document utilizes that representation to defines the HTTP 
encapsulation. 
The following criteria have been applied to the representation of CIM Operations 
in XML [2,11]: 
  Each CIM Operation is described completely in XML; completeness is favored 
  over conciseness.  
  The set of CIM Operations provide sufficient functionality to enable 
  implementations of CIM to communicate effectively for the purposes of 
  management. It is not a goal of the first release of this mapping to provide a 
  complete set of operations. It is a goal to define the mapping so as to admit 
  straightfoward extension (addition of further features) in future versions. 
  The set of CIM Operations are classified into functional profiles so that a 
  range of implementations (varying from complete support of all operations to 
  support of a minimal subset) is allowed. The number of functional profiles is 
  kept as small as possible to encourage interoperability, and mechanisms 
  provided by which CIM implementations can declare their level of support.
The following criteria have been applied to the HTTP encapsulation of CIM 
Operations herein: 
  In recognition of the large installed base of HTTP/1.0 systems, the 
  encapsulation is designed to support both HTTP/1.0 and HTTP/1.1 
  The encapsulation does not introduce any requirements which are in conflict 
  with those stated in HTTP/1.0 or HTTP/1.1 
  The encapsulation should be straightforwardly usable over the current base 
  HTTP infrastructures. Some features are intended to anticipate and exploit 
  enhancements to this base, but no aspects of the encapsulation require any 
  such enhancements as mandatory. 
  The encapsulation avoids the use of pure HTTP Tunnelling or URL munging (e.g. 
  the use of the "?" character) in favor of a mechanism which allows existing 
  HTTP infrastructures to safely control content. 
  The encapsulation exposes key CIM operation information in Headers to allow 
  efficient firewall/proxy handling.  The information is limited to that which 
  is considered essential, in order not to have significant impact on the size 
  of the Header. No CIM-specific information appears in a Header that does not 
  also appear within the CIM Operation. 
  There is a clear and unambiguous encapsulation of the CIM Operation payload 
  within the HTTP Message. Conciseness of the encapsulation is of secondary 
  importance.

1.2. Terminology
The key phrases and words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, 
SHOULD NOT, RECOMMENDED, MAY and OPTIONAL in this document are to be interpreted 
as described in RFC 2119 [8].
This specification uses the same notational conventions and basic parsing 
constructs as defined in [7].

2. CIM Operation Syntax and Semantics
2.1. Overview
This specification defines all interactions between CIM entities as Operations.  
CIM Operations belong to a larger category known as CIM Messages (currently all 
Messages are Operations, but in future this may not be true).
This section describes the syntax and semantics of CIM Operations in a manner 
independent of the encapsulation of such operations within a particular protocol 
(such as HTTP).
XML is used as the basis for this description, and in particular the CIM XML DTD 
[2,11].
Back to contents
2.1.1. Well-Formed, Valid and Loosely Valid
Where this document makes reference to the concept of a Well-formed or Valid XML 
documents, the meaning intended is the standard one defined in [3].
XML DTDs are restricted to these terms to describe XML documents, but this 
document requires a further classification of an XML document with respect to a 
DTD. Henceforth the term loosely valid is defined to apply to an XML Document 
with the following characteristics:
  If any attributes or elements in the XML document which do not appear in the 
  CIM XML DTD are removed, then the resulting document is valid with respect to 
  the CIM XML DTD.
In effect, a loosely valid document is one which is valid with respect to the 
CIM XML DTD apart from having additional attributes or elements not defined by 
that DTD. The concept is very similar to that of an open content model as 
defined by the working draft on XML Schemas [21], expressed within the more 
limited scope of DTDs. One corollary of this definition is that any XML document 
that is valid with respect to the CIM XML DTD is also loosely valid.
The motivation for introducing this class of XML Documents is to relax the 
restrictions on a CIM Client or a CIM Server when parsing received XML documents 
defined within the scope of this mapping. It is recognized that not all Clients 
(respectively, Servers) should be required to validate each received Operation 
Response Message (respectively, Operation Request Message) as this would place 
too great a processing burden on the validating entity at the expense of 
footprint and performance, most notably in communication between robust and 
conformant implementations of this mapping.
Instead the following requirements are made by this specification:
  A CIM Client (respectively, CIM Server) MAY include a DOCTYPE element in an 
  Operation Request Message (respectively, Operation Response Message). If so, 
  an External declaration SHOULD be used (in-lining of the complete DTD within a 
  message is discouraged). 
  A CIM Client (respectively, CIM Server) MAY elect to validate a received 
  Operation Response Message (respectively, Operation Request Message).  
  If a CIM Client (respectively, CIM Server) elects not to validate a received 
  Operation Response Message (respectively, Operation Request Message), then 
  loose validation MUST be enforced.
The behavior of a CIM Server with respect to a received Operation Request 
Message is covered in detail in the section on Errors and Status Codes .
2.2. Operational Semantics 
The CIM XML DTD [2,11] defines a subelement under the root <CIM> element called 
<MESSAGE>, which contains one of the following subelements:
  <SIMPLEREQ> 
  <SIMPLERSP> 
  <MULTIREQ> 
  <MULTIRSP>
In the remainder of this document:
  The term Operation Request Message denotes an XML document that is loosely 
  valid with respect to the CIM XML DTD, which contains under the root <CIM> 
  node a <MESSAGE> subelement, under which there is a <MULTIREQ> or <SIMPLEREQ> 
  subelement, and; 
  The term Operation Response Message denotes an XML document that is loosely 
  valid with respect to the CIM XML DTD, which contains under the root <CIM> 
  node a <MESSAGE> subelement, under which there is a <MULTIRSP> or <SIMPLERSP> 
  subelement.
An Operation Request Message MUST contain a non-empty value for the ID attribute 
of the <MESSAGE> element.  The corresponding Operation Response Message MUST 
supply the same value for that attribute.  Clients SHOULD employ a message ID 
scheme that minimizes the chance of receiving a stale Operation Response 
Message.
Any Operation Request Message or Operation Response Message conforming to this 
specification MUST specify a value of "1.0" for the PROTOCOLVERSION attribute of 
the <MESSAGE> element.
An Operation Response Message sent in response to an Operation Request Message 
MUST:
  specify the same value for the ID  attribute of the <MESSAGE> element as 
  appeared in the Operation Request Message, and 
    contain a <MULTIRSP> subelement if the Operation Request Message contained a 
    <MULTIREQ> subelement, or 
    contain a <SIMPLERSP> subelement if the Operation Request Message contained 
    a <SIMPLEREQ> subelement.
A Simple Operation Request is an Operation Request Message that contains a 
<SIMPLEREQ> subelement.  A Simple Operation Response is an Operation Response 
Message that contains a <SIMPLERSP> subelement.
A Multiple Operation Request is an Operation Request Message that contains a 
<MULTIREQ> subelement.  A Multiple Operation Response is an Operation Response 
Message that contains a <MULTIRSP> subelement.

2.3. Method Invocations
All CIM Operation requests defined for this mapping are defined as invocations 
of one or more methods.  A method may be either:
  Intrinsic, which means that it is defined by this specification for the 
  purposes of modelling a CIM operation, or; 
  Extrinsic, which means that it is defined as a method on a CIM Class in some 
  Schema.
Intrinsic methods are further characterized by the fact that they are made 
against a CIM Namespace.  Extrinsic methods are invoked on a CIM Class (if 
static) or Instance (otherwise). Intrinsic methods are defined in the section 
Intrinsic Methods
An extrinsic method call is represented in XML by the <METHODCALL> element, and 
the response to that call represented by the <METHODRESPONSE> element.  
An intrinsic method call is represented in XML by the <IMETHODCALL> element, and 
the response to that call represented by the <IMETHODRESPONSE> element.
An Input parameter is one with an IN Qualifier (with value true) in the Method 
definition.  An Output parameter is one with an OUT Qualifier (with value true) 
in the Method definition.  An Optional parameter is one with an OPTIONAL 
Qualifier in the Method definition. A parameter may be both an Input and Output 
parameter.
The <METHODCALL> or <IMETHODCALL> element serves to name the method to be 
invoked and supply any Input parameters to the method call. Note that:
  Each Input parameter MUST be named using the name assigned in the method 
  definition. 
  The Input parameters MAY be supplied in any order. 
  Each Input parameter of the method, and no others, MUST be present in the 
  call, unless it was defined as Optional.
The <METHODRESPONSE> or <IMETHODRESPONSE> element defines either an <ERROR> or a 
(possibly optional) return value and output parameters (i.e. one decorated with 
the OUT Qualifier in the method definition).  In the latter case:
  Each Output parameter MUST be named using the name assigned in the method 
  definition. 
  The Output parameters MAY be supplied in any order. 
  Each Output parameter of the method, and no others, MUST be present in the 
  response, unless it was defined as Optional.
The method invocation process may be thought of as:
  The binding of the input parameter values specified as subelements of the 
  <METHODCALL> or <IMETHODCALL> element to the input parameters of the Method, 
  followed by; 
  The attempted execution of the method using the bound input parameters, and; 
    If attempt to call the method is successful, the binding of the the return 
    value and output parameters to the subelements of the <METHODRESPONSE> or 
    <IMETHODRESPONSE> element, or; 
    If the attempt to call the method is unsuccesful, the binding of an error 
    code and (optional) human-readable description of that code to the 
    <METHODRESPONSE> or <IMETHODRESPONSE> element.

2.3.1. Simple Operations
A simple operation is defined as one that requires the invocation of a single 
method.  A simple operation request is represented by a <SIMPLEREQ> element, and 
a simple operation response by a <SIMPLERSP> element.
If the method is intrinsic then the <SIMPLEREQ> MUST contain a <IMETHODCALL> 
element, which in turn contains a <LOCALNAMESPACEPATH> subelement identifying 
the local CIM Namespace against which the method is to be executed.  If the 
method is extrinsic then the <SIMPLEREQ> element MUST contain a <METHODCALL> 
element which in turn contains either:
  A <LOCALCLASSPATH> subelement identifying the CIM Class on which the method is 
  to be invoked, in the case that the method is static, or; 
  An <LOCALINSTANCEPATH> subelement identifying the CIM Instance on which the 
  method is to be invoked, otherwise.
Back to contents
2.3.2. Multiple Operations
A multiple operation is defined as one that requires the invocation of more than 
one method.  A multiple operation request is represented by a <MULTIREQ> 
element, and a multiple operation response by a <MULTIRSP> element.
A <MULTIREQ> (respectively, <MULTIRSP>) element is a sequence of two or more 
<SIMPLEREQ> (respectively, <SIMPLERSP>) elements. 
A <MULTIRSP> element MUST contain a <SIMPLERSP> element for every <SIMPLEREQ> 
element in the corresponding Multiple Operation Response, and these <SIMPLERSP> 
elements MUST be in the same order as their <SIMPLEREQ> counterparts (so the 
first <SIMPLERSP> in the response corresponds to the first <SIMPLEREQ> in the 
request, and so forth). 
Multiple Operations provide a convenient mechanism whereby multiple method 
invocations may be batched into a single HTTP Message, thereby reducing the 
number of roundtrips between a CIM Client and a CIM Server and allowing the CIM 
Server to make certain internal optimizations should it choose so to do.  Note 
that Multiple Operations do not confer any transactional capabilities in the 
processing of the request (for example, there is no requirement that the CIM 
Server guarantee that the constituent method calls either all failed or all 
succeeded, only that the entity make a "best effort" to process the operation).
Not all CIM Servers support Multiple Operations; the means by which they declare 
support for this feature is defined in the section on Determining CIM Server 
Capabilities.
Back to contents
2.3.3. Status Codes
This section defines the status codes that may be returned by a conforming CIM 
Server application as the value of the CODE attribute of an <ERROR> subelement 
within a <METHODRESPONSE> or <IMETHODRESPONSE> element.
The symbolic names defined in the table below do not appear on the wire.  They 
are used here solely as a convenient way to refer to an error in other parts of 
this specification.
Not all methods would be expected to return all the status codes listed below.  
For intrinsic methods, the relevant section on each method in this specification 
defines the expected error codes to be returned.  For extrinsic methods the 
specification of which of the following codes can be used is described in the 
section on Extrinsic Method Invocation .
      Symbolic NameCODEDefinition 
      CIM_ERR_FAILED1A general error occured that is not covered by a more 
      specific error code
      CIM_ERR_ACCESS_DENIED2Access to a CIM resource was not available to the 
      client
      CIM_ERR_INVALID_NAMESPACE3The target namespace does not exist
      CIM_ERR_INVALID_PARAMETER4One or more parameter values passed to the 
      method were invalid
      CIM_ERR_INVALID_CLASS5The specified Class does not exist

      language
      CIM_ERR_METHOD_NOT_AVAILABLE16The extrinsic Method could not be executed
      CIM_ERR_METHOD_NOT_FOUND17The specified extrinsic Method does not exist

Back to contents
2.4. Intrinsic Methods
This section describes the Intrinsic methods that are defined outside of schema 
for the purposes of CIM operations.  These methods can only be called on a CIM 
Namespace, rather than a CIM Class or CIM Instance.
The following intrinsic methods are defined by this specification:
  Get a CIM Class 
  Get a CIM Instance 
  Delete a CIM Class 
  Delete a CIM Instance  
  Create a CIM Class 
  Create a CIM Instance 
  Modify a CIM Class 
  Modify a CIM Instance  
  Enumerate subclasses of a CIM Class 
  Enumerate subclass names of a CIM Class  
  Enumerate instances of a CIM Class 
  Enumerate instance names of a CIM Class  
  Delete a CIM Qualifier definition 
  Create a CIM Qualifier definition 
  Enumerate CIM Qualifier definitions 
  Execute a Query 
  Enumerate associators of a CIM Object 
  Enumerate names of associators of a CIM Object 
  Enumerate references to a CIM Object 
  Enumerate names of references to a CIM Object  
  Get a CIM Property value from a CIM Instance 
  Set a CIM Property value from a CIM Instance 
  Get a Qualifier declaration 
  Set a Qualifier declaration 
  Delete a Qualifier declaration 
  Enumerate Qualifier declarations
The convention used in the following subsections to define the signatures of the 
intrinsic methods is a pseudo-MOF notation that extends the standard MOF BNF [1] 
for describing CIM Methods with a number of pseudo parameter types (which are 
indicated by being placed within "<" and ">" characters). 
This notation admits of the decoration of parameters with a number of 
pseudo-qualifiers (IN, OPTIONAL and NULL) to define their invocation semantics. 
It is important to understand that these qualifiers are used for descriptional 
purposes only within the scope of this specification, and in particular a CIM 
Client MUST NOT specify them in intrinsic method invocations.
This notation uses the IN qualifier to denote that the parameter is an input 
parameter.
This notation uses the OPTIONAL qualifier to indicate paramaters whose presence 
is not mandatory, and declares default values for optional method parameters 
using similar notation employed for default property values in MOF.
A CIM Client MAY omit an optional parameter in the case that the required value 
is the specified default, by not specifying an <IPARAMVALUE> element for that 
parameter. It MUST NOT omit any parameter that is not marked as optional.
This notation uses the NULL qualifier to indicate parameters whose values may be 
be specified as NULL in a method call. A NULL (unassigned) value for a parameter 
is specified by an <IPARAMVALUE> element with no subelement. For parameters 
which do not possess the NULL qualifier, the CIM Client MUST specify a value for 
the parameter by including a suitable subelement for the <IPARAMVALUE> element 
for that parameter.
All parameters MUST be named uniquely, and MUST correspond to a valid parameter 
name for that method as described by this specification. The order of the 
parameters is not significant.
The non-NULL values of intrinsic method parameters or return values which are 
modelled as standard CIM types (such as string and boolean, or arrays thereof) 
are represented as follows:
  Simple values MUST be represented using the <VALUE> subelement within an 
  <IPARAMETER> element (for method parameters) or within an <IRETURNVALUE> 
  element (for method return values). 
  Array values MUST be represented using the <VALUE.ARRAY> subelement within an 
  <IPARAMETER> element (for method parameters) or within an <IRETURNVALUE> 
  element (for method return values).
The following table describes how each of the pseudo-types used by the intrinsic 
methods MUST be mapped to an XML element described in [2] in the context of both

2.4.1. GetClass
This operation is used to return a single CIM Class from the target Namespace.  
       GetClass
       <class>  GetClass (
               [IN] <className> ClassName,
               [IN,OPTIONAL] boolean LocalOnly = true,

               [IN,OPTIONAL,NULL] string PropertyList [] = NULL
       )

The ClassName input parameter defines the name of the Class to be retrieved.  
If the LocalOnly input parameter is true, this specifies that only CIM Elements 
(properties, methods and qualifiers) overriden within the definition of the 
Class are returned [1].  If false, all elements are returned.  This parameter 
therefore effects a CIM Server-side mechanism to filter certain elements of the 
returned object based on whether or not they have been propagated from the 
parent Class (as defined by the PROPAGATED attribute).
If the IncludeQualifiers input parameter is true, this specifies that all 
Qualifiers for that Class (including Qualifiers on the Class and on any returned 
Properties, Methods or Method Parameters) MUST be included as <QUALIFIER> 
elements in the response.  If false no <QUALIFIER> elements are present in the 
returned Class.
If the IncludeClassOrigin input parameter is true, this specifies that the 
CLASSORIGIN attribute MUST be present on all appropriate elements in the 
returned Class. If false, no CLASSORIGIN attributes are present in the returned 
Class.
If the PropertyList input parameter is not NULL, the members of the array define 
one or more Property names.  The returned Class MUST NOT include elements for 
any Properties missing from this list.  Note that if LocalOnly is specified as 
true this acts as an additional filter on the set of Properties returned (for 
example, if Property A is included in the PropertyList but LocalOnly is set to 
true and A is not local to the requested Class, then it will not be included in 
the response). If the PropertyList input parameter is an empty array this 
signifies that no Properties are included in the response. If the PropertyList 
input parameter is NULL this specifies that all Properties (subject to the 
conditions expressed by the other parameters) are included in the response.
If the PropertyList contains duplicate elements, the Server MUST ignore the 
duplicates but otherwise process the request normally.  If the PropertyList 
contains elements which are invalid Property names for the target Class, the 
Server MUST ignore such entries but otherwise process the request normally.
If successful, the return value is a single CIM Class.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional 
method-specific interpretation of the error in is given in parentheses.
  CIM_ERR_ACCESS_DENIED

  CIM_ERR_INVALID_PARAMETER (including missing, duplicate, unrecognized or

The ClassName input parameter defines the name of the Class to be deleted.    
If successful, the specified Class (including any subclasses and any instances) 
MUST have been removed by the CIM Server.  The operation MUST fail if any one of 
these objects cannot be deleted.

2.4.5. CreateClass
This operation is used to create a single CIM Class in the target Namespace.  
The Class MUST NOT already exist.
       CreateClass
       void CreateClass (
              [IN] <class> NewClass
       )

The NewClass input parameter defines the new Class.  The proposed definition 
MUST be a correct Class definition according to the CIM specification [1].
In processing the creation of the new Class, the following rules MUST be 
conformed to by the CIM Server:
  Any CLASSORIGIN and PROPAGATED attributes in the NewClass MUST be ignored by 
  the Server. 
  If the new Class has no Superclass, the NewClass parameter defines a new base 
  Class. The Server MUST ensure that all Properties and Methods of the new Class 
  have a CLASSORIGIN attribute whose value is the name of the new Class. 
  If the new Class has a Superclass, the NewClass parameter defines a new 
  Subclass of that Superclass. The Superclass MUST exist. The Server MUST ensure 
  that: 
    Any Properties, Methods or Qualifiers in the Subclass not defined in the 
    Superclass are created as new elements of the Subclass. In particular the 
    Server MUST set the CLASSORIGIN attribute on the new Properties and Methods 
    to the name of the Subclass, and ensure that all other Properties and 
    Methods preserve their CLASSORIGIN attribute value from that defined in the 
    Superclass. 
    If a Property is defined in the Superclass and in the Subclass, the value 
    assigned to that property in the Subclass (including NULL) becomes the 
    default value of the property for the Subclass. 
    If a Property or Method of the Superclass is not specified in the Subclass, 
    then that Property or Method is inherited without modification by the 
    Subclass. 
    Any Qualifiers defined in the Superclass with a TOSUBCLASS attribute value 
    of true MUST appear in the resulting Subclass. Qualifiers in the Superclass 
    with a TOSUBCLASS attribute value of false MUST NOT be propagated to the 
    Subclass. 
    Any Qualifier propagated from the Superclass cannot be modified in the 
    Subclass if the OVERRIDABLE attribute of that Qualifier was set to false in 
    the Superclass. It is a Client error to specify such a Qualifier in the 
    NewClass with a different definition to that in the Superclass (where 
    definition encompasses the name, type and flavor attribute settings of the 
    <QUALIFIER> element, and the value of the Qualifier).
If successful, the specified Class MUST have been created by the CIM Server.  
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional 
method-specific interpretation of the error in is given in parentheses.

       CreateInstance
       <instanceName>  CreateInstance (
              [IN] <instance> NewInstance
       )

The NewInstance input parameter defines the new Instance.  The proposed 
definition MUST be a correct Instance definition for the underlying CIM Class 
according to the CIM specification [1].
In processing the creation of the new Instance, the following rules MUST be 
conformed to by the CIM Server:
  Any CLASSORIGIN and PROPAGATED attributes in the NewInstance MUST be ignored 
  by the Server. 
  The Server MUST ensure that: 
    Any Qualifiers in the Instance not defined in the Class are created as new 
    elements of the Instance. 
    All Properties of the Instance preserve their CLASSORIGIN attribute value 
    from that defined in the Class. 
    If a Property is specified in the ModifiedInstance parameter, the value 
    assigned to that property in the Instance (including NULL) becomes the value 
    of the property for the Instance. Note that it is a Client error to specify 
    a Property that does not belong to the Class. 
    If a Property of the Class is not specified in the Instance, then that 
    Property is inherited without modification by the Instance. 
    Any Qualifiers defined in the Class with a TOINSTANCE attribute value of 
    true appear in the Instance. Qualifiers in the Class with a TOINSTANCE 
    attribute value of false MUST NOT be propagated to the Instance. 
    Any Qualifier propagated from the Class cannot be modified in the Instance 
    if the OVERRIDABLE attribute of that Qualifier was set to false in the 
    Class. It is a Client error to specify such a Qualifier in the NewInstance 
    with a different definition to that in the Class (where definition 
    encompasses the name, type and flavor attribute settings of the <QUALIFIER> 
    element, and the value of the Qualifier).
If successful, the return value defines the object path of the new CIM Instance 
relative to the target Namespace (i.e. the Model Path as defined by [1]), 
created by the CIM Server.  It is returned in case one or more of the new keys 
of the Instance are allocated dynamically during the creation process rather 
than specified in the request.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first

2.4.7. ModifyClass
This operation is used to modify an existing CIM Class in the target Namespace.  
The Class MUST already exist.
       ModifyClass
       void ModifyClass (
              [IN] <class> ModifiedClass
       )

The ModifiedClass input parameter defines the set of changes (which MUST be 
correct amendments to the CIM Class as defined by the CIM Specification [1]) to 
be made to the current class definition.
In processing the modifcation of the Class, the following rules MUST be 
conformed to by the CIM Server:
  Any CLASSORIGIN and PROPAGATED attributes in the ModifiedClass MUST be ignored 
  by the Server. 
  If the modified Class has no Superclass, the ModifiedClass parameter defines 
  modifications to a base Class. The Server MUST ensure that: 
    All Properties and Methods of the modified Class have a CLASSORIGIN 
    attribute whose value is the name of this Class. 
    Any Properties, Methods or Qualifiers in the existing Class definition which 
    do not appear in the  ModifiedClass parameter are removed from the resulting 
    modified Class.
  If the modified Class has a Superclass, the ModifiedClass parameter defines 
  modifications to a Subclass of that Superclass. The Superclass MUST exist, and 
  the Client MUST NOT change the name of the Superclass in the modified 
  Subclass. The Server MUST ensure that: 
    Any Properties, Methods or Qualifiers in the Subclass not defined in the 
    Superclass are created as elements of the Subclass. In particular the Server 
    MUST set the CLASSORIGIN attribute on the new Properties and Methods to the 
    name of the Subclass, and MUST ensure that all other Properties and Methods 
    preserve their CLASSORIGIN attribute value from that defined in the 
    Superclass. 
    Any Property, Method or Qualifier previously defined in the Subclass but not 
    defined in the Superclass, and which is not present in the ModifiedClass 
    parameter, is removed from the Subclass.  
    If a Property is specified in the ModifiedClass parameter, the value 
    assigned to that property therein (including NULL) becomes the default value 
    of the property for the Subclass. 
    If a Property or Method of the Superclass is not specified in the Subclass, 
    then that Property or Method is inherited without modification by the 
    Subclass (so that any previous changes to such an Element in the Subclass 
    are lost). 
    If a Qualifier in the Superclass is not specified in the Subclass, and the 
    Qualifier is defined in the Superclass with a TOSUBCLASS attribute value of 
    true, then the Qualifier MUST still be present in the resulting modified 
    Subclass (it is not possible to remove a propagated Qualifier from a 
    Subclass). 
    Any Qualifier propagated from the Superclass cannot be modified in the 
    Subclass if the OVERRIDABLE attribute of that Qualifier was set to false in 
    the Superclass. It is a Client error to specify such a Qualifier in the 
    ModifiedClass with a different definition to that in the Superclass (where 
    definition encompasses the name, type and flavor attribute settings of the 
    <QUALIFIER> element, and the value of the Qualifier). 
    Any Qualifiers defined in the Superclass with a TOSUBCLASS attribute value 
    of  false MUST NOT be propagated to the Subclass.
If successful, the specified Class MUST have been updated by the CIM Server.  
The request to modify the Class MUST fail if the Server cannot update any 
existing Subclasses or Instances of that Class in a consistent manner.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional 
method-specific interpretation of the error in is given in parentheses.

Namespace. The Instance MUST already exist.
       ModifyInstance
       void ModifyInstance (

The ModifiedInstance input parameter identifies the name of the Instance to be 
modified, and defines the set of changes (which MUST be correct amendments to 
the Instance as defined by the CIM Specification [1]) to be made to the current 
Instance definition. 
In processing the modifcation of the Instance, the following rules MUST be 
conformed to by the CIM Server:
  Any CLASSORIGIN and PROPAGATED attributes in the ModifiedInstance MUST be 
  ignored by the Server. 
  The Class MUST exist, and the Client MUST NOT change the name of the Class in 
  the modified Instance. The Server MUST ensure that: 
    Any Qualifiers in the Instance not defined in the Class are created as new 
    elements of the Instance. 
    All Properties of the Instance preserve their CLASSORIGIN attribute value 
    from that defined in the Class. 
    Any Qualifier previously defined in the Instance but not defined in the 
    Class, and which is not present in the ModifiedInstance parameter, is 
    removed from the Instance.  
    If a Property is specified in the ModifiedInstance parameter, the value 
    assigned to that property therein (including NULL) becomes the value of the 
    property for the Instance. Note that it is a Client error to specify a 
    Property that does not belong to the Class. 
    If a Property of the Class is not specified in the Instance, then that 
    Property is inherited without modification by the Instance (so that any

2.4.9. EnumerateClasses
This operation is used to enumerate subclasses of a CIM Class in the target

               [IN,OPTIONAL] boolean IncludeQualifiers = true,
               [IN,OPTIONAL] boolean IncludeClassOrigin = false
       )

The ClassName input parameter defines the Class that is the basis for the 
enumeration.  
If the DeepInheritance input parameter is true, this specifies that all 
subclasses of the specified Class should be returned (if the ClassName input 
parameter is absent, this implies that all Classes in the target Namespace 
should be returned).  If false, only immediate child subclasses are returned (if 
the ClassName input parameter is NULL, this implies that all base Classes in the 
target Namespace should be returned). 
If the LocalOnly input parameter is true, it specifies that, for each returned 
Class, only elements (properties, methods and qualifiers) overriden within the 
definition of that Class are included [1].  If false, all elements are returned. 
 This parameter therefore effects a CIM Server-side mechanism to filter certain 
elements of the returned object based on whether or not they have been 
propagated from the parent Class (as defined by the PROPAGATED attribute).
If the IncludeQualifiers input parameter is true, this specifies that all 
Qualifiers for each Class (including Qualifiers on the Class and on any returned 
Properties, Methods or Method Parameters) MUST be included as <QUALIFIER> 
elements in the response.  If false no <QUALIFIER> elements are present in each 
returned Class.
If the IncludeClassOrigin input parameter is true, this specifies that the 
CLASSORIGIN attribute MUST be present on all appropriate elements in each 
returned Class. If false, no CLASSORIGIN attributes are present in each returned 
Class.
If successful, the method returns zero or more Classes that meet the required 
criteria.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional

               [IN,OPTIONAL,NULL] string PropertyList [] = NULL
       )

The ClassName input parameter defines the Class that is the basis for the 
enumeration.    
If the LocalOnly input parameter is true, this specifies that, for each returned 
Instance, only elements (properties and qualifiers) overriden within the 
definition of that Instance are included [1].  If false, all elements are 
returned.  This parameter therefore effects a CIM Server-side mechanism to 
filter certain elements of the returned object based on whether or not they have 
been propagated from the parent Class (as defined by the PROPAGATED attribute).
If the DeepInheritance input parameter is true, this specifies that, for each 
returned Instance of the Class, all properties of the Instance MUST be present 
(subject to constraints imposed by the other parameters), including any which 
were added by subclassing the specified Class. If false, each returned Instance 
includes only properties defined for the specified Class.
If the IncludeQualifiers input parameter is true, this specifies that all 
Qualifiers for each Instance (including Qualifiers on the Instance and on any 
returned Properties) MUST be included as <QUALIFIER> elements in the response.  
If false no <QUALIFIER> elements are present in each returned Instance.
If the IncludeClassOrigin input parameter is true, this specifies that the 
CLASSORIGIN attribute MUST be present on all appropriate elements in each 
returned Instance. If false, no CLASSORIGIN attributes are present in each 
returned Instance.
If the PropertyList input parameter is not NULL, the members of the array define 
one or more Property names.  Each returned Instance MUST NOT include elements 
for any Properties missing from this list.  Note that if LocalOnly is specified 
as true (or DeepInheritance is specified as false) this acts as an additional 
filter on the set of Properties returned (for example, if Property A is included 
in the PropertyList but LocalOnly is set to true and A is not local to a 
returned Instance, then it will not be included in that Instance). If the 
PropertyList input parameter is an empty array this signifies that no Properties 
are included in each returned Instance. If the PropertyList input parameter is 
NULL this specifies that all Properties (subject to the conditions expressed by 
the other parameters) are included in each returned Instance.
If the PropertyList contains duplicate elements, the Server MUST ignore the 
duplicates but otherwise process the request normally.  If the PropertyList 
contains elements which are invalid Property names for any target Instance, the 
Server MUST ignore such entries but otherwise process the request normally.
If successful, the method returns zero or more named Instances that meet the 
required criteria.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional 
method-specific interpretation of the error in is given in parentheses.
  CIM_ERR_ACCESS_DENIED 
  CIM_ERR_NOT_SUPPORTED 
  CIM_ERR_INVALID_NAMESPACE  
  CIM_ERR_INVALID_PARAMETER (including missing, duplicate, unrecognized or 
  otherwise incorrect parameters)

The ClassName input parameter defines the Class that is the basis for the 
enumeration.  
If successful, the method returns zero or more names of Instances (model paths) 
that meet the requsted criteria.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional

2.4.13. ExecQuery
This operation is used to execute a query against the target Namespace.
       ExecQuery

               [IN] string QueryLanguage,
               [IN] string Query
       )

The QueryLanguage input parameter defines the query language in which the Query 
parameter is expressed.
The Query input parameter defines the query to be executed. 
Neither the Query language nor the format of the Query are defined by this 
specification.  It is anticipated that Query languages will be submitted to the 
DMTF as separate proposals.
A mechanism whereby CIM Servers can declare which query languages they support 
(if any) is defined in Determining CIM Server Capabilities.
If successful, the method returns zero or more CIM Classes or Instances that 
correspond to the results set of the query.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional 
method-specific interpretation of the error in is given in parentheses.

2.4.14. Associators
This operation is used to enumerate CIM Objects (Classes or Instances) that are 
associated to a particular source CIM Object.
       Associators
       <objectWithPath>* Associators (
               [IN] <objectName> ObjectName,
               [IN,OPTIONAL,NULL] <className> AssocClass = NULL,
               [IN,OPTIONAL,NULL] <className> ResultClass = NULL,
               [IN,OPTIONAL,NULL] string Role = NULL,

               [IN,OPTIONAL,NULL] string PropertyList [] = NULL
       )

The ObjectName input parameter defines the source CIM Object whose associated 
Objects are to be returned.  This may be either a Class name or Instance name 
(model path).
The AssocClass input parameter, if not NULL, MUST be a valid CIM Association 
Class name. It acts as a filter on the returned set of Objects by mandating that 
each returned Object MUST be associated to the source Object via an Instance of 
this Class or one of its subclasses. 
The ResultClass input parameter, if not NULL, MUST be a valid CIM Class name. It 
acts as a filter on the returned set of Objects by mandating that each returned 
Object MUST be either an Instance of this Class (or one of its subclasses) or be 
this Class (or one of its subclasses).
The Role input parameter, if not NULL, MUST be a valid Property name. It acts as 
a filter on the returned set of Objects by mandating that each returned Object 
MUST be associated to the source Object via an Association in which the source 
Object plays the specified role (i.e. the name of the Property in the 
Association Class that refers to the source Object MUST match the value of this 
parameter).
The ResultRole input parameter, if not NULL, MUST be a valid Property name. It 
acts as a filter on the returned set of Objects by mandating that each returned 
Object MUST be associated to the source Object via an Association in which the 
returned Object plays the specified role (i.e. the name of the Property in the 
Association Class that refers to the returned Object MUST match the value of 
this parameter).
If the IncludeQualifiers input parameter is true, this specifies that all 
Qualifiers for each Object (including Qualifiers on the Object and on any 
returned Properties) MUST be included as <QUALIFIER> elements in the response.  
If false no <QUALIFIER> elements are present in each returned Object.
If the IncludeClassOrigin input parameter is true, this specifies that the 
CLASSORIGIN attribute MUST be present on all appropriate elements in each 
returned Object. If false, no CLASSORIGIN attributes are present in each 
returned Object.
If the PropertyList input parameter is not NULL, the members of the array define 
one or more Property names.  Each returned Object MUST NOT include elements for 
any Properties missing from this list.  Note that if LocalOnly is specified as 
true (or DeepInheritance is specified as false) this acts as an additional 
filter on the set of Properties returned (for example, if Property A is included 
in the PropertyList but LocalOnly is set to true and A is not local to a 
returned Instance, then it will not be included in that Instance). If the 
PropertyList input parameter is an empty array this signifies that no Properties 
are included in each returned Object. If the PropertyList input parameter is 
NULL this specifies that all Properties (subject to the conditions expressed by 
the other parameters) are included in each returned Object.
If the PropertyList contains duplicate elements, the Server MUST ignore the 
duplicates but otherwise process the request normally.  If the PropertyList 
contains elements which are invalid Property names for any target Object, the 
Server MUST ignore such entries but otherwise process the request normally.
Clients SHOULD NOT explicitly specify properties in the PropertyList parameter 
unless they have specified a non-NULL value for the ResultClass parameter.
If successful, the method returns zero or more CIM Classes or Instances meeting 
the requested criteria.  Since it is possible for CIM Objects from different 
hosts or namespaces to be associated, each returned Object includes location 
information.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional 
method-specific interpretation of the error in is given in parentheses.

               [IN,OPTIONAL,NULL] string ResultRole = NULL
       )

The ObjectName input parameter defines the source CIM Object whose associated 
names are to be returned. This is either a Class name or Instance name (model 
path).
The AssocClass input parameter, if not NULL, MUST be a valid CIM Association 
Class name. It acts as a filter on the returned set of names by mandating that 
each returned name identifies an Object that MUST be associated to the source 
Object via an Instance of this Class or one of its subclasses. 
The ResultClass input parameter, if not NULL, MUST be a valid CIM Class name. It 
acts as a filter on the returned set of names by mandating that each returned 
name identifies an Object that MUST be either an Instance of this Class (or one 
of its subclasses) or be this Class (or one of its subclasses).
The Role input parameter, if not NULL, MUST be a valid Property name. It acts as 
a filter on the returned set of names by mandating that each returned name 
identifies an Object that MUST be associated to the source Object via an 
Association in which the source Object plays the specified role (i.e. the name 
of the Property in the Association Class that refers to the source Object MUST 
match the value of this parameter).
The ResultRole input parameter, if not NULL, MUST be a valid Property name. It 
acts as a filter on the returned set of names by mandating that each returned 
name identifies an Object that MUST be associated to the source Object via an 
Association in which the named returned Object plays the specified role (i.e. 
the name of the Property in the Association Class that refers to the returned 
Object MUST match the value of this parameter).
If successful, the method returns zero or more full CIM Class paths or Instance 
paths of Objects meeting the requested criteria.  Since it is possible for CIM 
Objects from different hosts or namespaces to be associated, each returned path 
is an absolute path that includes host and namespace information.
If unsuccessful, one of the following status codes MUST be returned by this 
method, where the first applicable error in the list (starting with the first 
element of the list, and working down) is the error returned. Any additional

The Role input parameter, if not NULL, MUST be a valid Property name. It acts as 
a filter on the returned set of Objects by mandating that each returned Objects 
MUST refer to the target Object via a Property whose name matches the value of 
this parameter.
If the IncludeQualifiers input parameter is true, this specifies that all 
Qualifiers for each Object (including Qualifiers on the Object and on any

2.5. Namespace Manipulation
There are no intrinsic methods defined specifically for the purpose of 
manipulating CIM Namespaces. However, the modelling of a CIM Namespace using the 
class __Namespace, together with the requirement that the root Namespace MUST be 
supported by all CIM Servers, implies that all Namespace operations can be 
supported.
For example:
  Enumeration of all child Namespaces of a particular Namespace is realized by 
  calling the intrinsic method EnumerateInstanceNames against the parent 
  Namespace, specifying a value for the ClassName parameter of __Namespace. 
  Creation of a child Namespace is realized by calling the intrinsic method 
  CreateInstance against the parent Namespace, specifying a value for the 
  NewInstance parameter which defines a valid instance of the class __Namespace 
  and whose Name property is the desired name of the new Namespace.
2.6. Functional Profiles
This section partitions the intrinsic methods into functional groups for the 
purpose of establishing conformance.
Support for a particular group does not guarantee that all invocations of any 
method in that group will succeed.  Rather, the exclusion of a group is a 
declaration that any attempt to call a method in that group will always return 
CIM_ERR_NOT_SUPPORTED.
Mechanisms by which a CIM Server may declare the functional groups that it 
supports are defined in the section on Determining CIM Server Capabilities.
In order to limit the number of different profiles that may be supported by a 
CIM Server, each functional group has a dependency on another group (with the 
exception of the Basic Read functional group).  If functional group G1 has a 
dependency on functional group G2, then a CIM Server which supports G1 MUST also 
support G2.  
The dependency relation is transitive, so that if G1 depends on G2, and G2 
depends on G3, then G1 depends on G3. It is also anti-symmetric, so that if G1 
depends on G2 then G2 cannot depend on G1.
Using these rules, the table below defines a rooted directed tree of 
dependencies with the Basic Read dependency representing the root node.  
For example, a CIM Server which supports the Schema Manipulation functional 
group MUST also support the Instance Manipulation, Basic Write and Basic Read.

2.7. Extrinsic Method Invocation
Any CIM Server is assumed to support extrinsic methods. Extrinsic methods are 
defined by the Schema supported by the Cim Server. If a Cim Server does not 
support extrinsic method invocations, it MUST (subject to the considerations 
described in the rest of this section) return the error code 
CIM_ERR_NOT_SUPPORTED to any request to execute an extrinsic method. This allows 
a CIM client to determine that all attempts to execute extrinsic methods will 
fail.
If the Cim Server is unable to perform the extrinsic method invocation, one of 
the following status codes MUST be returned by the CimServer, where the first 
applicable error in the list (starting with the first element of the list, and 
working down) is the error returned. Any additional specific interpretation of 
the error is given in parentheses. 
  CIM_ERR_ACCESS_DENIED 
  CIM_ERR_NOT_SUPPORTED (the CimServer does not support extrinsic method 
  invocations) 
  CIM_ERR_INVALID_NAMESPACE 
  CIM_ERR_INVALID_PARAMETER (including missing, duplicate, unrecognized or 
  otherwise incorrect parameters) 
  CIM_ERR_NOT_FOUND (the target CIM Class or instance does not exist in the 
  specified namespace) 
  CIM_ERR_METHOD_NOT_FOUND 
  CIM_ERR_METHOD_NOT_AVAILABLE (the CimServer is unable to honor the invocation 
  request) 
  CIM_ERR_FAILED (some other unspecified error occurred)

3. Encapsulation of CIM Operations
All CIM Operation requests MUST be made using either an HTTP M-POST or POST 
message, with the preferred mechanism being the use of M-POST. The use of other 
HTTP Methods to invoke CIM Operations is outside the scope of this 
specification.
All CIM Operation responses are carried in the corresponding HTTP Response 
message to the M-POST or POST request.
In the remainder of this document:
  the term CIM Operation Request is a convenient shorthand for an HTTP M-POST or 
  POST request message that includes an XML entity body which defines an 
  Operation Request Message, and; 
  the term CIM Operation Response is a convenient shorthand for an HTTP response 
  message, issued in response to a CIM Operation Request, that includes an 
  entity body which defines an Operation Response Message.  Note that an HTTP 
  response to a CIM Operation Request is not always a CIM Operation Response; 
  for example a "505 HTTP Version Not Supported" response would not be a CIM 
  Operation Response.
Where it is necessary to distinguish requirements between the use of M-POST and 
POST, these will be explicitly defined.
The extension mechanism used in this document is based on the HTTP Extension 
Framework [9]. A goal of the framework is to allow a decentralized naming 
mechanism whereby parties can introduce additional HTTP Headers without fear of 
conflicting interpretation of a given Header name.
It is not the intention of this document to replicate information in that 
document concerning the required behavior of entities that implement this 
framework; suffice it to say that conforming CIM implementations of this 
specification protocol MUST abide by all requirements in that document.

3.1. CIM Clients and Servers
The following definitions are used throughout the remainder of this document:
  A CIM client is an HTTP client that issues CIM Operation Requests and receives 
  and processes CIM Operation Responses. 
  A CIM server is an an HTTP server that receives and processes CIM Operation 
  Requests and issues CIM Operation Responses.
An HTTP client/server MAY be capable of acting as both a CIM client and a CIM 
server.
Back to contents
3.2. Use of M-POST and POST
A CIM client attempting a CIM Operation invocation conformant to this 
specification MUST first try the invocation using the HTTP method "M-POST". 
  If the M-POST invocation fails with an HTTP status of "501 Not Implemented" or 
  "510 Not Extended", then the client SHOULD retry the request using the HTTP 
  method POST with the appropriate modifications (described in Naming of 
  Extension Headers).  The intention is that POST should only be used as a 
  fallback mechanism in environments where firewalls or proxies do not yet have 
  the ability to understand M-POST requests. 
  If the M-POST invocation fails with an HTTP status of "405 Method Not 
  Allowed", then the client SHOULD fail the request. 
  For all other status codes the client MUST act in accordance with standard 
  HTTP [6,7].
This extended invocation mechanism allows Internet proxies & firewalls greater 
filtering control and administrative flexibility over CIM Operation invocations.
In the case of a client receiving a 501 or 510 status in response to an M-POST 
request, then in subsequent invocations to the same HTTP server, the client MAY 
omit the attempt at M-POST invocations for a suitable period, thus avoiding the 
need for an extra round trip on each and every method invocation.  The details 
of the caching strategy employed by the client are outside of the scope of this 
specification.
Given this algorithm, firewalls can if they wish effectively force the use of 
M-POST for CIM Operation invocations by prohibiting POST invocations containing 
the Extension Header CIMOperation. 
3.2.1. Use of the Ext Header
If a CIM Server receives a valid M-POST request, and has fulfilled all mandatory 
extension header declarations in the request, then it MUST include in the 
response the "Ext" header defined by [9].  This must be protected by the 
appropriate Cache-Control directive.
Back to contents
3.3. Extension Headers Defined for CIM Operation Requests and Responses
This section describes the extension headers used to specify CIM operational 
semantics in the HTTP Header of an M-POST or POST message.
Any CIM Operation Request or CIM Operation Response MUST include the following 
CIM extension header:
  CIMOperation 
Any CIM Operation Request MUST include one and only one of the following CIM 
extension header sets:
  CIMMethod and CIMObject, or 
  CIMBatch
An HTTP reponse with an error status code to a CIM Operation Request MAY include 
the following CIM extension header:
  CIMError 
All CIM Operation Requests and Responses MAY include the following CIM extension 
header:
  CIMProtocolVersion
Back to contents
3.3.1. Naming of Extension Headers
In M-POST request messages (and their responses), CIM extension headers MUST be 
declared using the name space prefix allotted by the "Man" extension header (in 
accordance with [9]) that refers to the name space 
"http://www.dmtf.org/cim/mapping/http/v1.0". 
The full format of the "Man" header declaration for this specification is:
      Man              = "Man" ":" "http://www.dmtf.org/cim/mapping/http/v1.0"
                         ";" "ns" "=" header-prefix
      header-prefix    = 2*DIGIT

This header-prefix SHOULD be generated at random on a per-HTTP message basis, 
and SHOULD NOT necessarily be a specific number.
In accordance with [9], all POST request messages (and their responses) MUST NOT 
include such a mandatory extension declaration. In POST request messages (and 
their responses), name space prefixes MUST NOT be used.
Example 1 
Using M-POST:
      M-POST /cimom HTTP/1.1
      Man: http://www.dmtf.org./cim/mapping/http/v1.0 ; ns=23
      23-CIMOperation: MethodCall
      ...

Example 2 
Using POST:
      POST /cimom HTTP/1.1
      CIMOperation: MethodCall
      ...

3.3.2. Encoding of CIM Element Names within HTTP Headers
CIM element (class, property, qualifier, method or method parameter) names are 
natively Unicode, and may use UCS-2 characters unsuitable for inclusion within 
an HTTP message header. In order to encode CIM element names represented in 
Unicode to values within HTTP Headers, the following mapping MUST be used:
  Encode the full Unicode CIM element name using UTF-8 [15], and then; 
  Apply the standard URI [16, section 2] escaping mechanism to the resulting 
  string to escape any characters that are unsafe within an HTTP Header, using 
  the ""%" HEX HEX" convention).
The token CIMIdentifier, where used in this document, represents a CIM element 
name to which this transformation has been applied.
One characteristic of this mapping is that CIM elements that are named with an 
ASCII representation will appear in ASCII in the resultant URL.
Examples 
      CIM_LogicalElement is unchanged under this transformation
      The class named using the UCS-2 sequence representing the Hangul 
      characters for the Korean word "hangugo" (D55C, AD6D, C5B4) becomes 
            %ED%95%9C%EA%B5%AD%EC%96%B4=10
      after UTF-8 transformation and escaping all characters with their % HEX 
      HEX equivalent. 

Back to contents
3.3.3. Encoding of CIM Object Paths within HTTP Headers
This section describes the mapping that MUST be applied in order to represent 
CIM object paths, as described within an Operation Request Message using the 
<LOCALNAMESPACEPATH>, <LOCALCLASSPATH> or <LOCALINSTANCEPATH> elements, in a 
format that is safe for representation within an HTTP header. 
If the element to be transformed is a <LOCALNAMESPACEPATH> element, the 
algorithm is as follows:
  For the first NAMESPACE subelement, output the textual content of that 
  element. 
  For each subsequent NAMESPACE subelement, output the forward slash character 
  (/) followed by the textual content of that NAMESPACE element. 
If the element to be transformed is a <LOCALCLASSPATH> element, the algorithm is 
as follows:
  Transform the <LOCALNAMESPACEPATH> subelement using the rules described above, 
  and output a colon character (:). 
  Output the value of the NAME attribute of the <CLASSNAME> subelement.
If the element to be transformed is an <LOCALINSTANCEPATH> element, the 
algorithm is as follows:
  Transform the <LOCALNAMESPACEPATH> subelement using the rules described above, 
  and output a colon character (:). 
  Output the value of the CLASSNAME attribute of the <INSTANCENAME> subelement. 
  If there is at least one <KEYBINDING> subelement under the <INSTANCENAME> 
  subelement, then for each such subelement: 
    Output a period character (.) if this is the first <KEYBINDING> subelement, 
    and a comma (,) otherwise. 
    Output the value of the NAME attribute, followed by an equals character (=). 

    If there is a <KEYVALUE> subelement, output the textual element content of 
    that element, subject to the following transformation: 
      If the VALUETYPE attribute is numeric or boolean, the output is identical 
      to the content of the element. 
      If the VALUETYPE attribute is string, the output is obtained by enclosing 
      the content of the element in double quote (") characters, and escaping 
      any double quote characters within the value with a preceding backslash 
      (\) character. 
    If there is a <VALUE.REFERENCE> subelement 
      output a double quote character ("). 
      apply the process recursively to the <CLASSPATH> or <INSTANCEPATH> 
      subelement of the <VALUE.REFERENCE> element, escaping any double quote 
      character or backslash character thereby generated with a preceding 
      backslash (\) character. 
      output a closing double quote character (").
  If there is no <KEYBINDING> subelement but there is a <KEYVALUE> or 
  <VALUE.REFERENCE> subelement under the <INSTANCENAME> subelement, then: 
    Output an equals character (=). 
    Output the transformed value of the <KEYVALUE> or <VALUE.REFERENCE>, using 
    the same rules as described above.
  If there were no <KEYBINDING> subelements, or no <KEYVALUE> or 
  <VALUE.REFERENCE> subelement, under the <INSTANCENAME> subelement then output 
  the string "=@" to indicate a singleton instance.
Finally, after applying the above rules to the <LOCALNAMESPACEPATH>, 
<LOCALCLASSPATH> or <LOCALINSTANCEPATH> element, transform the entire output 
string into URI-safe format as follows: 
  Encode the string using UTF-8 [15] if it is not already in this format, and 
  then; 
  Apply the standard URI [16, section 2] escaping mechanism to the resulting 
  string to escape any characters that are unsafe within an HTTP Header, using 
  the ""%" HEX HEX" convention).
The token CIMObjectPath, where used in this document, represents a 
<LOCALNAMESPACEPATH>, <LOCALCLASSPATH> or <LOCALINSTANCEPATH> element to which 
the above transformation has been applied.

3.3.4. CIMOperation
This header MUST be present in all CIM Operation Request and CIM Operation 
Response messages.  It identifies the HTTP message as carrying a CIM Operation 
request or response.
      CIMOperation = "CIMOperation" ":" ("MethodCall" | "MethodResponse")

A CIM Client MUST include this header, with the value "MethodCall", in all CIM 
Operation Requests that it issues.  A CIM Server MUST include this header in all 
CIM Operation Responses, with the value "MethodResponse", that it issues.
If a CIM Server receives CIM Operation request with this header, but with a 
missing value or a value that is not "MethodCall", then it MUST fail the request 
with status "400 Bad Request". The CIM Server MUST include a CIMError header in 
the response with a value of unsupported-operation.
If a CIM Server receives a CIM Operation request without this header, it MUST 
NOT process it as if it were a CIM Operation Request.  The status code returned 
by the CIM Server in response to such a request is outside of the scope of this 
specification.
If a CIM Client receives a response to a CIM Operation Request without this 
header (or if this header has a value which is not "MethodResponse"), it SHOULD 
discard the response, and take appropriate measures to publicize the fact that 
it has received an incorrect response.  The details as to how this is done are 
outside of the scope of this specification.
This header affords a simple mechanism by which firewall or proxy administrators 
can make global administrative decisions on all CIM Operations.
Back to contents
3.3.5. CIMProtocolVersion
This header MAY be present in any CIM Operation Request or CIM Operation 
Response message.  The header identifies the version of the CIM mapping onto 
HTTP being used by the sending entity.
      CIMProtocolVersion = "CIMProtocolVersion" ":" 1*DIGIT "." 1*DIGIT 

If the header is omitted, then a value of 1.0 MUST be assummed.
The major and minor numbers MUST be treated as independent integers which MAY be 
incremented higher than a single digit.  Therefore version x1.y1 is lower than 
x2.y2 if and only if:
  x1 is less than x2, or; 
  x1 equals x2, and y1 is less than y2
If a CIM Server receives an CIM Operation Request for which the value of this 
header indicates a version that it does not support, then it MUST respond in the 
manner defined in the section on Errors. 
Otherwise, if a CIM Server receives an CIM Operation Request for which the value 
of this header does not match the value of the PROTOCOLVERSION attribute of the 
<MESSAGE> element within the Operation Request, then it MUST fail the request 
and return a status of "400 Bad Request" (and MUST include a CIMError header in 
the response with a value of unsupported-protocol-version), subject to the 
considerations specified in Errors.
Back to contents
3.3.6. CIMMethod
This header MUST be present in any CIM Operation Request message that contains a 
Simple Operation Request.  
It MUST NOT be present in any CIM Operation Response message, nor in any CIM 
Operation Request message that is not a Simple Operation Request.
The header identifies the name of the CIM method to be invoked, encoded in an 
HTTP-safe representation.  Firewalls and proxies may use this header to carry 
out routing and forwarding decisions based on the CIM method to be invoked.
The name of the CIM method within a Simple Operation Request is defined to be 
the value of the NAME attribute of the <METHODCALL> or <IMETHODCALL> element.
      CIMMethod  = "CIMMethod" ":" MethodName
      MethodName = CIMIdentifier 

If a CIM Server receives a CIM Operation Request for which either:
  The CIMMethod header is present but has an invalid value, or; 
  The CIMMethod header is not present but the Operation Request Message is a 
  Simple Operation Request, or; 
  The CIMMethod header is present but the Operation Request Message is not a 
  Simple Operation Request, or; 
  The CIMMethod header is present, the Operation Request Message is a Simple 
  Operation Request, but the CIMIdentifier value (when unencoded) does not match 
  the unique method name within the Simple Operation Request,
then it MUST fail the request and return a status of "400 Bad Request" (and MUST 
include a CIMError header in the response with a value of header-mismatch), 
subject to the considerations specified in Errors.
Note that this verification provides a basic level of assurance that any 
intermediate firewall or proxy was not acting on misleading information when it 
decided to forward the request based on the content of the CIMMethod header.  
Additional securing of HTTP messages against modification in transit (such as 
the encryption of the payload or appending of a digital signature thereto) would 
be required to provide a higher degree of integrity.
Back to contents
3.3.7. CIMObject
This header MUST be present in any CIM Operation Request message that contains a 
Simple Operation Request.  
It MUST NOT be present in any CIM Operation Response message, nor in any CIM 
Operation Request message that that is not a Simple Operation Request.
The header identifies the CIM object (which MUST be a Class or Instance for an 
extrinsic method, or a Namespace for an intrinsic method) on which the method is 
to be invoked, using a CIM object path encoded in an HTTP-safe representation.  
Firewalls and proxies may use this header to carry out routing and forwarding 
decisions based on the CIM object that is the target of a method invocation.
      CIMObject  = "CIMObject" ":" ObjectPath
      ObjectPath = CIMObjectPath

The ObjectPath value is constructed by applying the algorithm defined in 
Encoding CIM Object Paths to either:
  The <LOCALNAMESPACEPATH> subelement of the <IMETHODCALL> element, or; 
  The <LOCALCLASSPATH> or <LOCALINSTANCEPATH> subelement of the <METHODCALL> 
  element
within the CIM Operation Request.
If a CIM Server receives a CIM Operation Request for which either:
  The CIMObject header is present but has an invalid value, or: 
  The CIMObject header is not present but the Operation Request Message is a 
  Simple Operation Request, or; 
  The CIMObject header is present but the Operation Request Message is not a 
  Simple Operation Request, or; 
  The CIMObject header is present, Operation Request Message is a Simple 
  Operation Request, but the ObjectPath value does not match (where match is 
  defined in the section on Encoding CIM Object Paths) the Operation Request 
  Message,
then it MUST fail the request and return a status of "400 Bad Request" (and MUST 
include a CIMError header in the response with a value of header-mismatch), 
subject to the considerations specified in Errors.
Note that this verification provides a basic level of assurance that any 
intermediate firewall or proxy was not acting on misleading information when it 
decided to forward the request based on the content of the CIMObject header.  
Additional securing of HTTP messages against modification in transit (such as 
the encryption of the payload or appending of a digital signature thereto) would 
be required to provide a higher degree of integrity.
Back to contents
3.3.8. CIMBatch
This header MUST be present in any CIM Operation Request message that contains a 
Multiple Operation Request.  
It MUST NOT be present in any CIM Operation Response message, nor in any CIM 
Operation Request message that is not a Multiple Operation Request.
The header identifies the encapsulated Operation Request Message as containing 
multiple method invocations.  Firewalls and proxies may use this header to carry 
out routing and forwarding decisions for batched CIM method invocations.
      CIMBatch = "CIMBatch" 

If a CIM Server receives a CIM Operation Request for which either:
  The CIMBatch header is present but has an invalid value, or: 
  The CIMBatch header is not present but the Operation Request Message is a 
  Multiple Operation Request, or; 
  The CIMBatch header is present but the Operation Request Message is not a 
  Multiple Operation Request,
then it MUST fail the request and return a status of "400 Bad Request" (and MUST 
include a CIMError header in the response with a value of header-mismatch), 
subject to the considerations specified in Errors.
Note that this verification provides a basic level of assurance that any 
intermediate firewall or proxy was not acting on misleading information when it 
decided to forward the request based on the content of the CIMBatch header.  
Additional securing of HTTP messages against modification in transit (such as 
the encryption of the payload or appending of a digital signature thereto) would 
be required to provide a higher degree of integrity.
If a CIM Server receives a CIM Operation Request for which the CIMBatch header 
is present, but the Server does not support Multiple Operations, then it MUST 
fail the request and return a status of "501 Not Implemented".  Firewalls or 
Proxies MAY also employ this mechanism to compel a CIM Client to use Simple 
Operation Requests rather than Multiple Operation Requests.
A CIM Client that receives a response of "501 Not Implemented" to a Multiple 
Operation Request SHOULD resubmit that request as a series of Simple Operation 
Requests. 
Back to contents
3.3.9. CIMError
This header MAY be present in any HTTP response to a CIM Operation Request 
message that is not a CIM Operation Response.  
It MUST NOT be present in any CIM Operation Response message, nor in any CIM 
Operation Request.
The header provides further CIM specific diagnostic information in the case that 
the CIM Server encountered a fundamental error during processing of the CIM 
Operation Request, and is intended to assist Clients to further disambiguate 
errors that have the same HTTP status code.
      CIMError  = "CIMError" ":" cim-error
      cim-error = "unsupported-protocol-version" |
                  "multiple-requests-unsupported" |
                  "unsupported-cim-version" |
                  "unsupported-dtd-version" |
                  "request-not-valid" |
                  "request-not-well-formed" |
                  "request-not-loosely-valid" |
                  "header-mismatch" |
                  "unsupported-operation"

4. HTTP Requirements & Usage
4.1. HTTP Support
It is RECOMMENDED that CIM clients and CIM servers support HTTP/1.1 [7].  CIM 
clients and servers MAY support HTTP/1.0 instead.  CIM clients and servers MUST 
NOT be limited to any version of HTTP earlier than 1.0.
It should be noted that the current revised draft [10] of RFC 2068 clarifies and 
corrects ambiguities and errors in that RFC.  
CIM Clients and Servers that make use of extension headers as defined in this 
specification MUST conform to the requirements defined in [9] for their use.
Back to contents
4.2. Use of Standard Headers
Unless otherwise stated herein, CIM clients and CIM servers MUST comply with the 
requirements on the use of headers described in [6,7]. This section defines only 
any additional requirements on CIM clients and servers with respect to the use 
of standard HTTP headers [6,7] within a CIM Operation Request or CIM Operation 
Response.  
Note that headers defined in RFC 2068 [7] but deprecated from [10] (e.g. Public, 
Content-Base) SHOULD NOT be used by CIM clients and servers.
4.2.1. Accept
If a CIM client includes an Accept header in a request, it MUST specify a value 
which allows the Server to return an entity body of "text/xml" or 
"application/xml" in the response.
A CIM server MUST accept any value for this header which states that "text/xml" 
or "application/xml" is an acceptable type for an response entity.  A server 
SHOULD return "406 Not Acceptable" if the Accept header indicates that neither 
of these content types are acceptable.
If a CIM server decides to accept a request to return an entity of type other 
than "text/xml" or "application/xml", the nature of the response is outside of 
the domain of this specification.
Back to contents 
4.2.2. Accept-Charset
If a CIM client includes an Accept-Charset header in a request, it MUST specify 
a value which allows the Server to return an entity body using the character set 
"utf-8".
A CIM server MUST accept any value for this header which implies that "utf-8" is 
an acceptable character set for an response entity.  A server SHOULD return "406 
Not Acceptable" if the Accept-Charset header indicates that this character set 
is not acceptable.
If a CIM server decides to accept a request to return an entity using a 
character set other than "utf-8", the nature of the response is outside of the 
domain of this specification.
See Internationalization Considerations for more details.
Back to contents 
4.2.3. Accept-Encoding
If a CIM client includes an Accept-Encoding header in a request, it MUST specify 
a value which allows the Server to use the "identity" encoding.
A CIM Server MUST accept any value for this header which implies that "identity" 
is an acceptable encoding for the response entity.  A server MAY return "406 Not 
Acceptable" if the Accept-Encoding header indicates that the this encoding is 
not acceptable.
Back to contents 
4.2.4. Accept-Language
If a CIM Client includes an Accept-Language header in a request, it SHOULD 
specify a value which allows the Server to return an entity in the language of 
its' own choosing.   This is accomplished by including in the list of acceptable 
language ranges the special range "*".
CIM Servers MAY support multiple languages if they so choose.
See Internationalization Considerations for more details.
Back to contents 
4.2.5. Accept-Ranges
CIM clients MUST NOT include this header in a request.  A CIM Server MUST reject 
a request that includes an Accept-Range header with a status of "406 Not 
Acceptable".
Back to contents 
4.2.6. Allow
If a CIM Server is returning a "405 Method Not Allowed" response to a CIM 
Operations Request then the Allow header MUST include either M-POST or POST.  
Whether it includes any other HTTP methods is outside the scope of this 
specification.
Back to contents 
4.2.7. Authorization
See the section on Security Considerations for more details.  
Back to contents 
4.2.8. Cache-Control
In general a CIM Operation Request may consist of a mixture of CIM method 
invocations, some of which may be eminently cachable (e.g. the Manufacturer 
label on a Disk Drive), and some of which may be decidedly uncachable (e.g. 
format a Disk Drive).  
Furthermore, the encapsulation of such multiple method invocations within an 
HTTP POST or M-POST means that if a CIM Operation Request has any effect on an 
HTTP cache it is likely to be one of invalidating cached responses for the 
target CIM Server.  Indeed HTTP/1.1[7] stipulates that by default POST responses 
are not cachable unless the server indicates otherwise using an appropriate 
Cache-Control or Expires header.
For these reasons, CIM Operation Responses SHOULD NOT be considered cachable.  A 
CIM Server SHOULD NOT include a Cache-Control header in a CIM Operation Response 
which might indicate to a cache that the response could be cached.  
If the CIM Server is responding to a CIM Operation Request coveyed within an 
M-POST request, then in accordance with [9] the Server MUST include a no-cache 
control directive to prevent inadvertant caching of the "Ext" header. For 
example:
      HTTP/1.1 200 OK
      Ext:
      Cache-Control: no-cache
      ...

Back to contents
4.2.9. Connection
It is RECOMMENDED that 
  CIM clients should avoid the use of the "Connection: close" header unless it 
  is known in advance that this is the only request likely to be sent out on 
  that connection. 
  CIM servers support persistant connections wherever possible. 
Timeout mechanisms SHOULD be employed to remove idle connections on both client 
and server, the details of which are outside the domain of this specification. 
Clients SHOULD be cautious in retrying requests, especially if they are not 
idempotent (e.g. method invocation). 
CIM clients and servers SHOULD support pipelining [7, section 1.1.2.2] if 
possible, but be aware of the requirements defined in [7].  In particular, 
attention is drawn to the following requirement from [7]:
  Clients SHOULD NOT pipeline requests using non-idempotent methods or 
  non-idempotent sequences of methods...A client wishing to send a 
  non-idempotent request SHOULD wait to send that request until it has received 
  the response status for the previous request. 
Back to contents
4.2.10. Content-Encoding
If a CIM client includes a Content-Encoding header in a request, it SHOULD 
specify a value of "identity", unless it has good reason to believe that the 
Server can accept another encoding.

4.3. Errors and Status Codes
This section defines how CIM Servers MUST handle errors that occur in the 
processing of a CIM Operation Request. This specification does not introduce any 
new HTTP response status codes.
If there is an error in processing the HTTP Request-Line or standard HTTP 
Headers then the CIM Server MUST take the appropriate action as dictated by its 
conformance to the relevant version of HTTP [6,7].
Otherwise, if there are any mandatory extension declarations which the server 
does not support it MUST respond with a "510 Not Extended" status according to 
[9].
Otherwise, the Server MUST process the request in accordance with the relevant 
version of HTTP [6,7] and the additional rules defined in this document.
Assuming that the HTTP request is otherwise correct, the CIM Server MUST use the 
following status codes when processing the CIM Extension Headers:
  501 Not Implemented One of the following occured:
    The CIMProtocolVersion extension header specified in the request specifies a 
    version of the CIM Mapping onto HTTP which is not supported by this CIM 
    Server. The CIM Server MUST include a CIMError header in the response with a 
    value of unsupported-protocol-version. 
    The Client specified a Multiple Operation Request and the CIM Server does 
    not support such requests. The CIM Server MUST include a CIMError header in 
    the response with a value of multiple-requests-unsupported. 
    The CIMVERSION attribute in the Operation Request was not set to a value of 
    "2.0". The CIM Server MUST include a CIMError header in the response with a 
    value of unsupported-cim-version. 
    The DTDVERSION attribute in the Operation Request was not set to a value of 
    "2.0". The CIM Server MUST include a CIMError header in the response with a 
    value of unsupported-dtd-version.
  401 Unauthorized The CIM Server is configured to require that a client 
  authenticate itself before it can issue CIM Operation Requests to the Server.
  403 Forbidden The CIM Server does not allow the client to perform CIM 
  Operations.  The CIM Server MAY alternatively respond with a "404 Not Found" 
  if it does not wish to reveal this information to the client.
  407 Proxy Authentication Required The CIM Server is configured to require that 
  the proxy authenticate itself before it can issue CIM Operation Requests on 
  behalf of a CIM Client to the Server.
Assuming that the CIM Extension Headers are correct, then a validating CIM 
Server (one which is enforcing validity of the Operation Request Message with 
respect to the CIM XML DTD) MUST use the following status code when processing 
the entity body containing the CIM Operation request.
  400 Bad Request The entity body defining the CIM Operation request was not 
  well-formed or not valid with respect to the CIM XML DTD. The CIM Server MUST 
  include a CIMError header in the response with a value of 
  request-not-well-formed or request-not-valid (as appropriate).
A loosely-validating CIM Server (one that is only enforcing that the CIM 
Operation Request be loosely valid) MAY reject an Operation Request Message that 
is not loosely valid with an HTTP status code of 400 (Bad Request) before 
further processing, in which case the CIM Server MUST include a CIMError header 
in the response with a value of request-not-loosely-valid. 
A loosely-validating CIM Server MUST reject an Operation Request Message that is 
not well-formed with an HTTP status code of 400 (Bad Request), in which case the 
CIM Server MUST include a CIMError header in the response with a value of 
request-not-well-formed. 
A loosely-validating CIM Server MUST NOT reject an invalid (in the XML sense) 
Operation Request Message that is loosely valid.
A loosely-validating CIM Server MUST ultimately signal an error to the CIM 
Client if the Operation Request Message is not loosely valid (i.e. is missing 
required content, or for which the required content is incorrect, such as an 
attribute with an invalid value according to the CIM XML DTD).  It is not 
mandated to reject an Operation Request before processing, for to do otherwise 
would compel the Server into checking the complete request before processing 
could begin and this would be as expensive as requiring that the Server fully 
validate the request. Therefore a loosely-validating Server MAY elect to begin 
processing the request and issuing a response (with an HTTP success status code) 
before checking that the entire request is loosely valid.
A CIM Client may determine whether a CIM Server is validating or 
loosely-validating via the CIMValidation header mechanism.
Assuming that the CIM operation request was correctly formed (in the manner 
described above), the CIM Server MUST process the request accordingly and return 
a CIM Operation Response response.  
The entity body MUST be a correct Operation Response Message for that request.  
If the CIM Operation Response contains an entity which is a Simple Operation 
Response then the response status must be 200 OK.  Otherwise the response status 
MUST be 207 Multistatus .

4.4. Security Considerations
CIM Clients and CIM Servers MAY elect not to use authentication, but only in 
environments where lack of security is not an issue.
Basic Authentication is described in [6,7].  Digest Authentication is defined in 
[12].  Both authentication schemes are covered in a consolidated document [14] 
which also makes a number of improvements to the original specification of 
Digest Authentication.
Basic Authentication provides a very rudimentary level of authentication, with 
the major weakness that the client password is sent over the wire in unencrypted 
form. 
For this reason CIM Clients and CIM Servers MUST NOT use Basic Authentication 
other than in the context of a highly secure environment (for example, if used 
in conjunction with SSL, or in a physically secure private network).  CIM 
Servers MUST NOT send Basic Authentication credentials in a WWW-Authenticate 
header other than in the context of a highly secure environment.
Conforming applications SHOULD support the Digest authentication scheme. Since 
Digest authentication verifies that both parties share a common secret, without 
having to send that secret in the clear, it is more secure than Basic 
authentication.  However, CIM Clients and CIM Servers that require more robust 
protection SHOULD use encyption mechanisms such as SSL or SHTTP.
CIM Clients and CIM Servers using Basic or Digest Authentication MUST comply 
with the requirements set forth in [6,7,12,14].  This specification describes 
only additional requirements on CIM Clients and CIM Servers when using these 
authentication schemes.
CIM Servers SHOULD require that CIM Clients authenticate themselves.  This 
specification does not mandate this as it is recognized that in some 
circumstances the CIM Server may not require or wish the overhead of employing 
authentication.  CIM Servers SHOULD consider carefully the performance/security 
tradeoffs in determining how often to issue challenges to CIM Clients.
A CIM Server that returns a "401 Unauthorized" response to a CIM Operation 
Request SHOULD include in the WWW-Authenticate response-header either the 
"Basic" or "Digest" authentication values (but not both).  This specification 
does not mandate use of Basic or Digest Authentication as it is recognized that 
in some circumstances the CIM Server may use bespoke authentication mechanisms 
not covered by [14].  Similar considerations apply to the use of the 
Proxy-Authorization header in  "407 Proxy Authentication Required".

4.5. Determining CIM Server Capabilities
The OPTIONS method MAY be used by a client to determine the CIM capabilities (if 
any) of the target server.  A CIM Server MAY support the OPTIONS method (for 
example, CIM Servers supporting only HTTP/1.0 would not support OPTIONS).
In order to support the ability for a Server to declare its CIM capabilities in 
a manner independent of HTTP, it is the intention of the DMTF to publish a CIM 
Schema (in a separate document) describing such capabilities. In particular this 
mechanism would allow Servers that do not support the OPTIONS method to declare 
their capabilities to a Client.
If a CIM Server supports the OPTIONS method, it SHOULD:
  Return the CIM Extension Header CIMProtocolVersion in the response.  This 
  provides a way for a client to discover the version of the CIM HTTP mapping 
  supported by the CIM Server. 
  Return the CIM Extension Header CIMSupportedFunctionalGroups in the response.  
  This provides a way for a client to discover the CIM Operations supported by 
  the CIM Server. 
  Return the CIM Extension Header CIMSupportsMultipleOperations in the response. 
   This provides a way for the client to discover whether the CIM Server can 
  support Multiple Operation Requests.
In addition, if the CIM Server supports one or more query languages, it SHOULD:
  Return the CIM Extension Header CIMSupportedQueryLanguages in the response.  
  This allows the client to discover the query languages supported by the CIM 
  Server.
In addition, if the CIM Server runs in a fixed validation mode, it SHOULD:
  Return the CIM Extension Header CIMValidation in the response.  This allows 
  the client to determine whether the CIM Server is strictly validating or 
  loosely validating.
If the CIMProtocolVersion, CIMSupportedFunctionalGroups, 
CIMSupportsMultipleOperations, CIMValidation or CIMSupportedQueryLanguages 
extension headers are included in the response, the CIM Server MUST declare them 
as Optional extension headers using the "Opt" header defined in [9].
The full format of the "Opt" header declaration for this specification is:
      Opt              = "Opt" ":" "http://www.dmtf.org/cim/mapping/http/v1.0"
                         ";" "ns" "=" header-prefix
      header-prefix    = 2*DIGIT

This header-prefix SHOULD be generated at random on a per-HTTP message basis, 
and SHOULD NOT necessarily be a specific number.
For example the following is a fragment of a legitimate OPTIONS response from a 
CIM Server:
      HTTP/1.1 200 OK
      Opt: http://www.dmtf.org/cim/mapping/http/v1.0 ; ns=77
      77-CIMProtocolVersion: 1.0
      77-CIMSupportedFunctionalGroups: basic-read
      77-CIMBatch
      77-CIMSupportedQueryLanguages: wql
      ...

Back to contents
4.5.1. CIMSupportedFunctionalGroups
The CIMSupportedFunctionalGroups extension header SHOULD be returned by a CIM 
Server in any OPTIONS response.  It MUST NOT be returned in any other scenario.
This header is defined as follows:
      CIMSupportedFunctionalGroups  = "CIMSupportedFunctionalGroups" ":" 
      1#functional-group

      functional-group     = "basic-read" |
                             "basic-write" |
                             "schema-manipulation" |
                             "instance-manipulation" |
                             "qualifier-declaration" |
                             "association-traversal" |
                             "query-execution"

The functional group definitions correspond directly to those listed in 
Functional Profiles.  All CIM Servers MUST support the basic-read functional 
group.  All CIM Clients MAY assume that any CIM Server supports the basic-read 
functional group.
The list of functional groups returned by a CIM Server MUST contain the 
basic-read group, and MUST NOT contain any duplicates.  CIM Clients MUST ignore 
any duplicate entries in the functional-group list.
If a functional group is included in the list, then the CIM Client MUST assume 
that all other groups on which it depends (according to the rules defined in 
Functional Profiles) are also supported.  A CIM Server SHOULD NOT explicitly 
include a functional group in the list whose presence may be inferred implicitly 
by a dependency.
For example the following HTTP response message indicates that the CIM Server 
supports instance-manipulation, association-traversal, basic-write and 
basic-read.
      HTTP/1.1 200 OK
      Opt: http://www.dmtf.org/cim/mapping/http/v1.0 ; ns=77
      77-CIMProtocolVersion: 1.0
      77-CIMSupportedFunctionalGroups: association-traversal, 
      instance-manipulation
      ...

Support for a functional group does not imply that any method from that group 
will always succeed.  Rather, the absence (whether explicit or implied) of the 
functional group from this header is an indication to the CIM Client that 
methods in that group will never succeed.

4.5.2. CIMSupportsMultipleOperations
The CIMSupportsMultipleOperations extension header MUST be returned in an 
OPTIONS response by any CIM Server that supports Multiple Operation Requests.  
It MUST NOT be returned in any other circumstances.
This header is defined as follows:
      CIMSupportsMultipleOperations  = "CIMSupportsMultipleOperations"

The presence of this header indicates that the Server can accept and process 
Multiple Operation Requests.  The absence of this header indicates that the 
Server can only accept and process Simple Operation Requests.
Back to contents
4.5.3. CIMSupportedQueryLanguages
The CIMSupportedQueryLanguages extension header SHOULD be returned by a CIM 
Server that supports at least one query language in any OPTIONS response.  It 
MUST NOT be returned in any other scenario.
This header is defined as follows (token has the meaning conferred by [7, 
section 2.2]:
      CIMSupportedQueryLanguages  = "CIMSupportedQueryLanguages" ":" 
      1#query-language

      query-language     = token

The query-language value MUST be treated as case-insensitive. It is anticipated 
that query languages will be submitted for approval to the DMTF, and each 
submission will define a value for this token to enable it to be specified in 
this header.
Back to contents
4.5.4. CIMValidation
The CIMValidation extension header MAY be returned by a CIM Server to provide 
information concerning the level of validation of CIM Operation Request 
messages.
This header is defined as follows:
      CIMValidation    = "CIMValidation" ":" validation-level
      validation-level = "validating" |
                         "loosely-validating"

A validation-level of validating indicates that the CIM Server will always apply 
strict validation of each CIM Operation Request. A validation-level of 
loosely-validating indicates that the CIM Server will apply loose validation of 
each CIM Operation Request.
In the absence of this header, a CIM Client SHOULD assume that the CIM Server 
operates in strict validation mode.

4.6. Other HTTP Methods
This specification does not in any way define or constrain the manner in which a 
CIM Client or Server uses any HTTP Method other than those explicitly referred 
to herein.
Back to contents
4.7. Discovery and Addressing
The target URI of the CIM Operation Request is defined to be the location of the 
CIM Server.  This specification does not constrain the format of this URI other 
than it be a valid URI [13] for the purposes of describing an HTTP-addressable 
resource.
An HTTP Server which supports the CIM Mapping defined herein, and which supports 
the OPTIONS method, SHOULD include the following CIM extension header in an 
OPTIONS response:
  CIMOM
This header is defined as follows:
      CIMOM        = "CIMOM" ":" (absoluteURI | relativeURI)

The terms absoluteURI and relativeURI are taken from [7]; they indicate the 
location of the CIM Server for this HTTP Server.
If the CIMOM extension header is included in the response, the CIM Server MUST 
declare it an Optional extension header in an analagous fashion to that 
described in the section on Determining CIM Server Capabilities.
A CIM Client that wishes to communicate with a CIM Server on an HTTP Server 
SHOULD try an OPTIONS request to that HTTP Server.  If the OPTIONS request 
fails, or the response does not include the CIM-CIMOM extension header, then the 
CIM Client MAY assume that the value of CIM-CIMOM is the relative URI cimom.
Other discovery mechanisms are outside the scope of this version of the 
specification.
Example 1
This example shows an HTTP Server located at http://www.dmtf.org issuing an 
OPTIONS response to an HTTP client to indicate that its CIM Server is located at 
http://www.dmtf.org/access/cimom.
      HTTP/1.1 200 OK
      Opt: http://www.dmtf.org/cim/mapping/http/v1.0 ; ns=48
      48-CIMOM: /access/cimom
      ...

Example 2
If an HTTP Server located at http://www.dmtf.org responds with a "501 Not 
Implemented" to an OPTIONS request from a CIM Client, the CIM client may then 
try to contact the CIM Server at http://www.dmtf.org/cimom.

4.8. Internationalization Considerations
This section defines the capabilities of the CIM HTTP Mapping with respect to 
IETF policy guidelines on character sets and languages [19].
In this specification, human-readable fields can be found within a response or 
request entity body.  In all cases, any human-readable content is encoded using 
XML (which has explicit provisions for character set tagging and encoding) and 
requires that XML processors read XML elements encoded, at minimum, using the 
UTF-8 [15] encoding of the ISO 10646 multilingual plane. 
XML examples in this specification demonstrate use of the charset parameter of 
the Content-Type header, as defined in [10], as well as the XML encoding 
attribute on the <?xml> processing instruction, which together provide charset 
identification information for MIME and XML processors. This specification 
mandates that conforming applications MUST support at least the "utf-8" charset 
encoding [19] in the Content-Type header, and the "utf-8" value for the XML 
encoding attribute. 
XML also provides a language tagging capability for specifying the language of 
the contents of a particular XML element, based on use of IANA registered 
language tags [20] in the xml:lang attribute of an XML element to identify the 
language of its content and attributes.  The XML CIM DTD [2,11] does not declare 
this attribute on any of the XML elements, and therefore conforming applications 
MUST NOT use this attribute as otherwise the XML document would not be valid 
with respect to that DTD.
This specification defines a number of names of HTTP headers and their values.  
These are constructed using standard encoding practices so as to always have an 
HTTP-safe ASCII representation.  Since these headers are not in general visible 
to users they do not need to support encoding in multiple character sets.
The XML DTD for CIM [2,11] introduces a number of XML element names.  Similarly 
these are not visible to an end user and do not need to support multiple 
character set encodings.
The CIM model [1] defines the subset of the Unicode character set that can be 
used to name CIM elements (Classes, Instances, Methods, Properties, Qualifiers 
and Method Parameters).  In general these appear as the value of XML attributes 
or as element content, and in general would not be displayed to end users.
Values of CIM Properties and Qualifiers, and error message descriptions MAY be 
localizable, but there is no mandate on CIM Servers to support this.  
Negotiation and notification of language settings is effected in this mapping 
using the standard Accept-Language and Content-Language headers defined in [7].
