A snapshot from Jeremy?

I actually noticed this problem when I was testing them myself last Friday. The property element eg:prop1 has an empty literal value, not a blank node, and that is the statement that is reified with ID "reify" (http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-not-id-and-resource-attr/test003.rdf#reify) and associated with the bag ID "bag" (http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-not-id-and-resource-attr/test003.rdf#bag). The fix I've approved for http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-not-id-and-resource-attr/test003.nt is: 19c19 < <http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-not-id-and-resource-attr/test003.rdf#reify> <http://www.w3.org/1999/02/22-rdf-syntax-ns#object> _:j88097 . --- > <http://www.w3.org/2000/10/rdf-tests/rdfcore/rdfms-not-id-and-resource-attr/test003.rdf#reify> <http://www.w3.org/1999/02/22-rdf-syntax-ns#object> "" . Can you confirm this fixes it for you? > > Regards --- Jan > > P.s. Using SWI-Prolog from the CVS snapshot it processes the rest of > the test-suite properly now. Excellent! Dave
