Paul, I usually author in Turtle and then distill to other formats to do this kind of stuff. The form your looking for for your example is the following:

<?xml version="1.0" encoding="UTF-8"?>
<rdf:RDF xmlns:foo="http://example.org/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xml:base="">
  <rdf:Description rdf:about="http://server/path/temppersonresource">
    <rdf:type rdf:resource="http://server/path/Person"/>
    <foo:country-name>US</foo:country-name>
  </rdf:Description>
</rdf:RDF>

Much easier to write as Turtle:

@prefix foo: <http://example.org/> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

<http://server/path/temppersonresource> a <http://server/path/Person>;
   foo:country-name "US" .

You can use my online service to validate and transform between representations. It's at http://rdf.greggkellogg.net/distiller.

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
