RDF has no such - pragmatic - mechanism. What of inverse functional properties? e.g. <personA> foaf:homepage <http://example.org/home> . <personB> foaf:homepage <http://example.org/home> . tells me <personA>and <personB> are the same person because this plus foaf:homepage rdf:type owl:InverseFunctionalProperty . => <personA> owl:sameAs <personB> . Do PSIs offer any more than this? (Forgive me, it's been a long time since I read up on TMs, and even then I didn't get a particularly good understanding).
