It is a burden to carry this prefix file and maintain it, but its better than not being able to do anything about it.

There was some concern that the current text fragment (e.g. part_of) would be replaced with a semantic free identifier (e.g. RO_0000001). They confirmed this is the case. The discussion stemmed from concern that our Atlas Triples use predicates which are also in this form and there was a concern that it makes querying harder. Alan Ruttenberg had the following useful suggestion (I would also be keen to know if this resolves the concerns on the call or if I missed something more fundamental) for sparql they can write: prefix part_of:<http://purl.**obolibrary.org/obo/RO_0000000<http://purl.obolibrary.org/obo/RO_0000000> > then query: ?a part_of: ?b SPARQL processors should allow something like: @include_prefixes<http://foo.**org/ro_prefixes.txt<http://foo.org/ro_prefixes.txt> > Cheers, James -- European Bioinformatics Institute, Wellcome Trust Genome Campus, Cambridge, CB10 1SD, United Kingdom Tel: + 44 (0) 1223 494 676 Fax: + 44 (0) 1223 494 468
