Dear Jim, Many thanks. This is all wonderful the hear. If the person who's lab is responsible for developing and supporting one of the most widely used DIG reasoners says "these things are not mutually exclusive in any way", I've got much more confidence that all will be OK. :-) Does t

p.s. note that there was a lot of earlier discussion on this list about the need for more scalable OWL solutions in the short term - that was one of the motivations that got us thinking in that direction... -- Prof James Hendler [EMAIL PROTECTED] Dept of Compute

Bill - I think you see the key point - these things are not mutually exclusive in any way - high end ontology use needs some of the OWL 1.1 functionality, but wider adoption is likely to come in the data integration space, where a lot can be done with the simpler "OWL Mini" (or OWL Fast, or OWL

However, I'd point out, in the last document, where they describe a mapping of OWL 1.1 to RDF, they make the following caveat: Not every OWL 1.1 ontology can be serialized in RDF. In particular, ontologies using the following features of OWL 1.1 cannot be serialized: 1. punning and 2.

Hi All, I wanted to give more "legs" to this discussion point that came up at the end of today's HCLSIG TCon, as I think it's extremely important for us users of RDF & OWL. Sorry - I don't mean to be a "Chicken Little" on this issue - but as someone who needs to make practical technical r
