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 ;) Mika Nyman schrieb: > Hello Guenther & others > > We have also done an OWL-implementation of the CIDOC-CRM 4.2 for our own > use.
