Wouldn't it be better to encode this like so; as a proper graph,  
rather than using so many blank nodes?

<rdf:RDF xmlns:odf="http://docs.oasis-open.org/opendocument/meta/ 
package#"
             xmlns:dct="http://purl.org/dc/terms/";>

   <odf:Package rdf:about="urn:uuid:224ab023-77b8-4396- 
a75a-8cecd85b81e3">
     <odf:hasPart rdf:resource="urn:uuid: 
321fc314-69d3-4019-859d-29a5dc2721a0"/>
     <odf:hasPart rdf:resource="urn:uuid:afdc453c-5dc8-4988-8dab- 
fc378bd9e73d"/>
   </odf:Package>

   <odf:ContentFile rdf:about="urn:uuid: 
321fc314-69d3-4019-859d-29a5dc2721a0" odf:path="content.xml"/>

   <odf:Element rdf:about="urn:uuid:afdc453c-5dc8-4988-8dab- 
fc378bd9e73d" odf:idref="someID"/>

   <odf:File rdf:about="http://rdf-named-graph/calendar/vcard";  
odf:path="meta/calendar/vcard.rdf">
     <rdf:type rdf:resource="http://www.w3.org/2006/vcard/ns#"/>
     <rdf:type rdf:resource="http://calendar/data"/>
     <dct:references rdf:resource="urn:uuid:afdc453c-5dc8-4988-8dab- 
fc378bd9e73d">
   </odf:File>

</rdf:RDF>

Not sure I have the details precisely right (am in a hurry) but this  
general approach is cleaner, simpler, and also less verbose ...
