## Annotation of GO Identifiers to GO Terms

### Description

This data set gives mappings between GO identifiers and their respective terms.

### Details

Each GO identifier is mapped to a `GOTerms` object that has 6 slots:

GOID
  GO Identifier
Term
  The term for that GO id
Synonym
  Synonymous terms
Secondary
  Secondary terms that have been merged into this term
Definition
  Further definition of the GO term
Ontology
  One of MF - molecular function, BP - biological process, or CC - cellular component

All the obsolete GO terms are under the nodes "obsolete molecular function" (GO:0008369), "obsolete cellular component" (GO id GO:0008370), and "obsolete biological process" (GO:0008371). Each of these GO identifiers has a group of GO identifiers as their direct children with GO terms that were defined by GO but are deprecated in the current build. These deprecated GO terms were appended by "(obsolete)" when the data package was built.

Mappings were based on data provided by: Gene Ontology ( ftp://ftp.geneontology.org/pub/go/godatabase/archive/latest ) on 200708

        # Convert the object to a list
        xx <- as.list(GOTERM)
        if(length(xx) > 0){
            # Get the TERMS for the first elent of xx
            GOID(xx[[1]])
            Term(xx[[1]])
            Synonym(xx[[1]])
            Secondary(xx[[1]])
            Definition(xx[[1]])
            Ontology(xx[[1]])
        }
