I wrote that rdf:Property and rdfs:Class are instances of rdfs:Class. I(rdf:Property) is in ICEXT(I(rdfs:Class)) I(rdfs:Class) is in ICEXT(I(rdfs:Class)) This is not the same as saying they are subclasses of rdfs:Class. ICEXT(I(rdf:Property)) subset of ICEXT(I(rdfs:Class)) # probably not true ICEXT(I(rdfs:Class)) subset of ICEXT(I(rdfs:Class)) As it happens rdfs:Class is a subclass of rdfs:Class, but nothing in RDFS suggests that rdf:Property is a subclass of rdfs:Class. If you're seeing something in what I wrote that implies that rdf:Property is a subclass of rdfs:Class, please point it out to me. -- Dave Menendez - zednenem@psualum.com - http://www.eyrie.org/~zednenem/
