Hey,
It's a shame that project fell by the wayside. If your looking for an OWL
ecore metamodel take a look at the UML2OWL stuff available at
http://perso.univ-lr.fr/ghillair/projects.html I've used it alot and it is
very usefull. Some of the older versions used an RDF ecore metamodel which
may interest you too.
Regards,
Ronan
