FWIW and IMHO let me point out that the single greatest innovation of SHOE that made it all the way into OWL (through the various intervening languages) was basing ontologies on URIs so that linking and mapping could happen -- OWL can be used to create mapping ontologies, ontologies can evolve by extending each other -- cross ontology reasoning is the thing that makes Semantic Web different from all other AI ontology work to date - and I've written plenty of papers on why it is hard, why it is imprtant, how we can get a handle on doing some of it - etc. I do think there are some nice doctoral theses to be done (and I'm hiring students to do them) in automating more of the mapping (human provides partial map, system extends it) within the sorts of mappings that OWL allows, but doing this by humans, using ontology tools, is presently well within the state of the practice and easy to do .... I think I talked about this a bunch at my ISWC talk -- hmm, yes, I did -- check out the second major section of [1] -JH [1] http://iswc2003.semanticweb.org/hendler_files/v3_document.htm -- Professor James Hendler http://www.cs.umd.edu/users/hendler 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 240-277-3388 (Cell)
