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:

Cheers,
Bill
