NAME

OBO::APO::GoaToRDF - A GOA associations to RDF converter.

DESCRIPTION

Converts a GOA association file to a RDF graph. The RDF graph is very simple, containing a node for each line from the association file (called GOA_ASSOC_n), and several triples for the fields (e.g. obj_symb).

GOA associations files can be obtained from http://www.ebi.ac.uk/GOA/proteomes.html

The method 'work' gets an assoc file path and a file handler for the RDF graph.
