Dear Ian, Ulrike & Bijan, Thank you so much for your speedy & comprehensive replies. To clarify, I was indeed talking about using a rules engine to do OWL reasoning; Bijan, you're right about the imprecision of what a "rule" is (and I'm not clear, either. The work I'm doing at the moment uses very simple horn-clause rules with variables that are unified with terms from the ABox). Also, the distinction between data-heavy and axiom heavy reasoning. The reason it came up was a) because it seems to be a perennial problem and b) there seem to be some existing techniques (like backward chaining) that I can't immediately see how one would implement when your data is the ABox of an ontology. Thanks a lot, Matt
