Dear all,

this is great. So I'll throw in yet another OWL representation
that I have done in 2004 (and which it is a bit aged by now), for
discussion and comparison:
  http://cidoc.ics.forth.gr/OWL/releasenotes349.html

I agree with Martin's suggestion to nominate a coordinator and I'd
be happy if Günther Goerz would volunteer for this effort.

-- Detlev

P.S.: Apparently, this situation is not too unusual: The MPEG-7
community has managed to produce four or five OWL representations
of ISO 15938-5 largely independent of each other. And all of these
had even been described in journal and conference papers.
This is the information society at work ;)
