The first objective IMO is to be able to integrate SKOS instances in an 
OWL-DL framework. Using the SKOS vocabulary to label OWL elements is of 
course appealing, but potentially confusing, and I'm not sure it's such 
a good idea. OWL-DL has deliberately sacrified the linguistic aspects of 
naming on the autel of logic, by putting NL labels and languages outside 
the semantics. I think we (SKOS) should not mess up with that, or try to 
patch that bug of OWL-DL which is actually a deliberate built-in feature 
(AFAIK)
But both OWL and SKOS should be clear on this. Want logic, rules, 
inference, go the OWL-DL way but forget about dealing with the 
linguistic aspects (or build your own ad hoc classes and properties). In 
SKOS you'll have linguistic aspects in the semantics (hopefully at the 
end of the day).
