In broad brush-strokes, we are committed to a query concrete syntax which is grounded in a widely-adopted (and preferably W3C recommended) representation. Further, in no means do I intend to imply that XQuery would make things easier on the vendor implementations for RDFS/OWL/Rule components of the SemWeb - quite the opposite, the implementations may even be more difficult. Our point is intended to speak towards our opinion that a known query representation would speed user adoption rates for semantic web languages. If early adopters of large commercial organizations were faced with learning and implementing a wholly new syntax for queries - on top of what they already have to pay for in human resource expertise - we suspect, and have encountered, resistance. Anecdotally, we would likely be supportive of the OWL "two surface realizations" model, as long as one of them was a widely-adopted standard format. -Jeff- sounds like we're near the same page -- guess what I'm having trouble w/is the "widely-adopted standard format" -- since I haven't seen the Xquery proposal, I've been assuming it is some sort of specialization of Xquery much as RDQL is a "SQL-like" langauge -- guess I'm thinking that most large commercial orgs have lots of people who speak SQL and could learn RDQL-like langauge without thinking of it as different (I speak from experience, I've met a lot of govt folks who have used RDQL with RDF DBs because "they didn't need any training" - which is more or less a direct quote from someone telling me why he didn't take a SemWeb training course some colleagues were teaching) where Xquery is not yet on their todo list. On the other hand, it is clear more people will move to Xquery as XML DBs slowly get accepted and steal market share from traditional RDBMS DBs (although right now it is pretty clear which one if David and which is Goliath) .. so I think I would agree with you that "as long as one of them was a widely-adopted standard format", although I'm less sure we would agree which is which :-> -JH -- 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)
