Re: First vCard in RDF and FOAF Future Telecon: May 27th 2:00 UTC (immediately after SWXG telecon)

Addendum:

According to

http://www.mygrid.org.uk/OWL/Validator

the current 2006 spec at

http://www.w3.org/2006/vcard/ns.rdf

is not OWL DL but OWL Full.

Immediate suggestions  from my side (imcomplete and not 100% sure, but 
first steps):

- define dc:title etc. as annotation properties before using them
- remove the cardinality constraints - i have doubts they do exactly 
what is intended anyway
- the following snippet looks a bit strange at first sight (maybe okay, 
but I don't get it immediately):

   <owl:DatatypeProperty rdf:about="http://www.w3.org/2006/vcard/ns#rev">
      <rdfs:comment>The timestamp of a revision of a vCard</rdfs:comment>

      <rdfs:label>revision</rdfs:label>
      <rdfs:domain rdf:resource="http://www.w3.org/2006/vcard/ns#VCard"/>
      <rdfs:range rdf:parseType="Resource">
         <owl:unionOf rdf:parseType="Resource">
            <rdf:first 
rdf:resource="http://www.w3.org/2001/XMLSchema#date"/>
            <rdf:rest rdf:parseType="Resource">
               <rdf:first 
rdf:resource="http://www.w3.org/2001/XMLSchema#dateTime"/>
               <rdf:rest 
rdf:resource="http://www.w3.org/1999/02/22-rdf-syntax-ns#nil"/>

            </rdf:rest>
         </owl:unionOf>
      </rdfs:range>
   </owl:DatatypeProperty>
