At the moment I think in some other note(s).  The relationship between SKOS and OWL, and best practises regarding their combined use, is something that probably needs a bit of time and some more discussion.  E.g. see the section 'Relationship to RDFS/OWL ontologies' in the latest editor's draft of the SKOS Core Guide [1] (which is a sort of tentative position statement regarding the hefty 'skos:denotes' discussion we had last year :).  

Also in previous drafts of the Guide there was a section on 'extending SKOS Core' which included using OWL to define classes of concepts (see [2]). But I think the subject of 'extending' SKOS Core should be covered in a separate note (which is why it's cut from the latest editor's draft).

I do think that a best practises kind of note showing how you can do cool extra stuff with SKOS like you suggested in [3] by using a bit of OWL would be great - let's add that to the wishlist :)

Cheers,

Al.
