My reason for preferring this is that it then becomes extensible - but also because if it will be easier for a tool to scan for ontology declarations if it doesn't need to do inferencing to get there. I'd suggest something like <owl:ontology owl:level="lite" rdf:about=""> <owl:imports .../> <owl:version .../> </owl:ontology> If I've read the new RDF documents correctly, this is legal, clean and an easy way to provide that mechanism. -JH p.s. I can live with the subclassing, just find this somewhat preferable as it will make things a little easier for my tool builders. -- Professor James Hendler hendler@cs.umd.edu Director, Semantic Web and Agent Technologies 301-405-2696 Maryland Information and Network Dynamics Lab. 301-405-6707 (Fax) Univ of Maryland, College Park, MD 20742 240-731-3822 (Cell) http://www.cs.umd.edu/users/hendler
