package org.apache.commons.rdf.api

Commons RDF, a common library of RDF 1.1 concepts.

The core RDF 1.1 concepts are represented by corresponding interfaces:

A Graph is a collection of Triples, which have a subject, predicate and object of RDFTerms. The three types of RDF terms are IRI, Literal and BlankNode.

Implementations of this API should provide an RDF to facilitate creation of these objects.

All the RDFTerm objects are immutable, while a Graph MAY be mutable (e.g. support methods like Graph.add(Triple)).

RDFSyntax enumerates the W3C standard RDF 1.1 syntaxes and their media types.

For further documentation and contact details, see the Commons RDF web site.

Class	Description
BlankNode	A RDF-1.1 Blank Node, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014. Note: Blank nodes are disjoint from IRIs and literals.
BlankNodeOrIRI	This interface represents the RDFTerms that may be used in the subject position of an RDF-1.1 Triple as well as the graph name position of a Quad.
Dataset	An RDF 1.1 Dataset, a set of RDF quads, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014.
Graph	An RDF 1.1 Graph, a set of RDF triples, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014.
GraphLike<T extends TripleLike>	A "graph-like" interface that contains TripleLike statements.
IRI	An RDF-1.1 IRI, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014.
Literal	An RDF-1.1 Literal, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014.
Quad	A Quad is a statement in a RDF-1.1 Dataset, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Working Group Note published on 25 February 2014.
QuadLike<G extends RDFTerm>	A generalised "quad-like" interface, extended by Quad.
RDF	A RDF implementation.
RDFSyntax	An RDF syntax, e.g.
RDFTerm	An RDF-1.1 Term, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014.
RDFTermFactory	Deprecated.
Triple	An RDF-1.1 Triple, as defined by RDF-1.1 Concepts and Abstract Syntax, a W3C Recommendation published on 25 February 2014.
TripleLike	A generalised "triple-like" interface, extended by Triple and Quad.
W3CRDFSyntax	W3C RDF 1.1 serialization syntax.
W3CRDFSyntax.FormatIRI	IRI representing a W3C RDF format.
