I had a similar question recently (about including geographical
locations in FOAF), but there was no clear consensus. What I finally
wound up doing was to declare my own namespace as a container, then
tossing some vCard and Point info into it:

 xmlns:point="http://dublincore.org/documents/2000/07/28/dcmi-point/"
 xmlns:vCard="http://www.w3.org/2001/vcard-rdf/3.0#"
 xmlns:geo="http://dougal.gunters.org/geography/"

      <geo:location rdf:ID="HometownLocation">
        <rdf:Description>
          <dc:description>Hometown location</dc:description>
        </rdf:Description>
        <vCard:GEO>
          <vCard:LAT>31.358978</vCard:LAT>
          <vCard:LON>-85.816314</vCard:LON>
        </vCard:GEO>
        <vCard:ADR>
          <vCard:Locality>Enterprise</vCard:Locality>
          <vCard:Region>Alabama</vCard:Region>
          <vCard:Pcode>36330</vCard:Pcode>
          <vCard:Country>us</vCard:Country>
          <rdf:type rdf:resource="http://www.w3.org/2001/vcard-rdf/3.0#home"/>
          <rdf:type rdf:resource="http://www.w3.org/2001/vcard-rdf/3.0#pref"/>
        </vCard:ADR>
        <point:Point name="Enterprise, AL">
          <point:north>31.358978</point:north>
          <point:east>-85.816314</point:east>
        </point:Point>
      </geo:location>
