Hi group,

the RDF/XML file currently at


hase an error in that all system classes use the OWL namespace, e.g.

   <Class rdf:about="&owl;AllDifferent">
         <comment>The class of collections of pairwise different  
         <isDefinedBy rdf:resource="&owl;"/>
         <subClassOf rdf:resource="&rdfs;Resource"/>

This does not only mean that the system classes are now instances of  
owl:Class, but also that properties such as owl:comment are used. The  
properties interestingly have the correct rdf:type.

I guess the conversion script had an error.
