I suggest that you look at Jeff Heflin's doctoral thesis (Towards the Semantic Web: Knowledge Representation in a Dynamic, Distributed Environment [1]) which backed the SHOE language with two different DBs - one was XSB, the other was Parka-DB [2]. Parka-DB is the current winner in putting an ontology into a relational DB (with respect to scaling and having some built in inferencing), and we are working on solving some licensing problems so that we can release it in some open source forum. -Jim Hendler [1] http://www.cs.umd.edu/~heflin/dissert/ [2] http://www.cs.umd.edu/projects/plus/Parka/parka-db.html -- 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) AV Williams Building, Univ of Maryland College Park, MD 20742 http://www.cs.umd.edu/users/hendler
