FWIW, I think Sandro's proposal is consistent with the current state of RDF specification, and other views of URIs that have been expressed here, except maybe the view that http: URIs (without fragments) should always denote documents (I hope I don't misinterpret). My point of divergence with that proposal is the suggestion it should be part of the RDF core, because I don't see the necessity for it to be there. The formal semantics for RDF does tell us one thing, though: in a given interpretation of an RDF graph (document, or collection of documents considered together), a given URI must always denote the same single thing. So we can't have a graph in which a URI sometimes denotes a car and elsewhere simultaneously denotes a picture. #g ------------------- Graham Klyne <GK@NineByNine.org>Received on Thursday, 23 January 2003 06:42:17 GMT
