I have regenerated the SKOS DL version from Antoine's revision [6]. A  
reminder that this is produced by /throwing away/ some of the axioms  
in the ontology, namely:

         1. Removes all content using skos:definition, dct:issued,  
         dc:contributor, dc:description, dc:title, dct:creator,
         dct:contributor, dct:description and dct:title

         2. Removes axioms relating to semantic condition S11  
(labelling properties
         are subproperties of rdfs:label)

         3. Removes axioms relating to semantic condition S17  
(documentation properties
         are subproperties of skos:note)

         3. Removes axiom relating to semantic condition S33 (range  
of skos:memberList).

         The resulting schema is then a valid OWL DL document.

         Note that this is only one of a number of possible  
transformations. For example,
         condition S11 could be retained, with the typing of the  
labelling properties adjusted
         to be owl:DatatypeProperty.
