rdf:type

Hello, Im a complete beginner with rdf.

Im using the ruby rdf xml libraries ( rdf/rdfxml)

How would I create a <rdf:type rdf:resource="http://server/path/Person"/>
Entry as a child of rdf:description ?

Ie like this sample


<rdf:Description rdf:about="http://server/path/temppersonresource">

       <j.3:country-name>US</j.3:country-name>

      <rdf:type rdf:resource="http://server/path/Person"/>

    </rdf:Description>


I have created the rdf:description ok, as well as various statements, but am stumped on the type.


Hope that is enough of an explanation.


Thanks


Paul
