I just noticed an editorial (?) tweak (pointed out by pfps) to the semantics document that the semantic constraint that properties must be a subset of resources has been removed from the current editors draft. http://www.w3.org/2001/sw/RDFCore/TR/WD-rdf-mt-20030117/#interp Pat, this is rather more than just an editorial tweak. 1. M&S states that properties are a subset of resources 2. Object oriented implementations of RDF typically have property objects that are subclass of resources - is that still an accurate design? 3. I've seen no last call comment that justifies the change The claim in the change log that it does not affect entailments is false. Test case: sss ppp ooo . rdf entail ppp rdf:type rdf:Resource . I believe the answer should be yes, but in any case the answer is distinguishable in RDF. Brian
