Hi Jos, Thanks! Your last sentence: " That is indeed *possible* in RDF and OWL Full" is rather alarming to me as being seen by you as substandard. If this were to comply with the constraints of OWL DL, how should I model it? (your assumption about the base URI was correct).

So let me ask this question: If I have: > > <owl:Thing rdf:ID="Mustang"/> > <owl:Thing rdf:about="#Mustang"> > <rdf:type rdf:resource="http://www.example.org/library#Mustang"/> > </owl:Thing> > > then does this mean that I have here the class extension? What is the base URI for that rdf:ID="Mustang"? If it is http://www.example.org/library# then <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#" xmlns:owl="http://www.w3.org/2002/07/owl#" xml:base="http://www.example.org/library#"> <owl:Thing rdf:ID="Mustang"/> <owl:Thing rdf:about="#Mustang"> <rdf:type rdf:resource="http://www.example.org/library#Mustang"/> </owl:Thing> </rdf:RDF> is saying that :Mustang rdf:type :Mustang. or saying that :Mustang is in it's own extension (and :myMustang is also in that extension) That is indeed *possible* in RDF and OWL Full -- Jos De Roo, AGFA http://www.agfa.com/w3c/jdroo/
