Hi Dave,

just FYI, I made a few other changes to
http://www.w3.org/2005/11/its/rdf-content/its-rdf.rdf
(see the auto-generated updated N3 version at the end of this mail)
based on Sebastian's feedback. These are again conversions from "data 
type property" to "object property".

I don't know an answer to your concerns, Dave, and hope that Sebastian 
can reply, esp. the need to point to an OWL instance.

Best,

Felix
