Re: SKOS Instance V Classes

Dear Helmut and all

Maybe it's my fault but I think there is a misunderstanding. The notion of
skos:Concept is an owl:Class but each skos:Concept (i.e. the education, the
trains, etc) is an OWL instance. And in OWL-DL the sets of classes and
instances are disjoint.

Documentation -and some solutions on implementing OWL classes in SKOS-
could be found on section “5.2 SKOS Concepts and OWL Classes” of the SKOS
Primer available at https://www.w3.org/TR/skos-primer/#secskosowl

Kind Regards

Manolis
