I am struggling to find any documentation about the correct predicate to use the Gene Ontology (for annotation) in a RDF setting i.e.
<gene_id> < ???? > <go_term>
go2rdf.pl (from ONTO-Perl) uses
has_function (presumably from the
OBO_REL). On the other hand the GO has go:association that "represents the gene associations of each term.". Is this an explicitly symmetric property is this even of rdf:Property type?
