re sameAs I just looked and couldn't find it either. I'm not sure now if my original find was rdfs:sameAs or owl:sameAs. In either case, it seems to have been willed out of existence by the current update of documents. What I did find just now: http://www.w3.org/TR/2002/WD-owl-features-20020729/ OWL Lite sameClassAs samePropertyAs sameIndividualAs differentIndividualFrom ============ Dick McCullough knowledge := man do identify od existent done knowledge haspart list of proposition ----- Original Message ----- From: Frank Manola To: Richard H.

RDFS can't describe reality. It can describe some parts of reality, adequately for many useful purposes (as a number of people have found). Richer languages (like OWL) can describe more of reality, and still richer languages can describe even more of reality. But it seems as if we're fated to want to use different language to talk about reality, even the small corner of reality dealing with computer languages for describing (parts of) reality! --Frank -- Frank Manola The MITRE Corporation 202 Burlington Road, MS A345 Bedford, MA 01730-1420 mailto:fmanola@mitre.org voice: 781-271-8147 FAX: 781-271-875
