actually, we're trying to move the discussion to [EMAIL PROTECTED]
there's a thread there that expresses some of my concerns about
moving away from the OWL syntax - given that the primary tools out
there right now still assume the OWL is integrated with the RDF
graph...

As I expected, the experts are listening. :-)
Many thanks, Holger. That's extremely important to know.
I will dig into the thread for more detail. One main concern would
be whether that was just a token gesture to stay compatible for now,
as opposed to a commitment to remain compatible, until or unless an
effective alternative is provided to representing very large
knowledgebases in RDF.
I think more than anything I was a bit overwhelmed by the collective
picture given by those half-dozen or so presentations from last
week's meeting. The meeting seemed "fresh" enough, so that it could
be expected to be reflective of the status quo. I assume there was
much heated discussion during the meeting, that would have filled out
such detail - or such has been carried out on the owl-dev list.
I suppose it's also a good idea to dig into the OWL Extensions list
hosted by Jim Hendler's lab:

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. annotations on axioms.
Please see a recent thread on the public-owl-dev mailing list about
this:

Bijan states:
"The RDF mapping has lagged behind the others, but the plan is to
extend the mapping to cover these cases."
