(Sorry, that I send my first mail too early accidently.) I wanted to add
that you are hitting an interesting spot here. I agree that RDF and OWL
tools and - even more important - their communities should not be too
separated. However, I believe that the upcoming OWL 2 standard does not
have a negative impact here. Every OWL 2 ontology can be mapped to RDF
and vice versa. Furthermore, OWL 2 has been extended to simplify tool
support and solve some practival problems, e.g. the specification is now
accompanied by UML diagrams, axioms can be annotated, entities can be
used as instances and classes through punning etc. Summed up, I believe
that if there will be a split between OWL and RDF communities (which we
should avoid), then - from my point of view - this is unlikely to be the
fault of the upcoming OWL 2 standard.

Kind regards,

Jens
