From our own discussions, it is not clear to me what is being offered as a reason not to simply drop owl:class and use rdfs:class (or just make them equivalent if we resolve the open issue to have everything be owl:) -JH -- 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
