title: Newbie question: how to express relationships with rdf?
body: <p>I know this sounds extremely newbieish, but even after going through some of the tutorials on W3 schools on RDF and reading the primer, I cannot seem to fathom how a simple subject-predicate-object rdf relationship is expressed in XML.</p>
  
  <p>Let's say I have a concept like this: </p>
  
  <p>I have a car.
  My car has a gps receiver.
  The car's current gps coordinates are X latitude, Y longitude.</p>
  
  <p>Do I represent this as </p>
  
  <pre><code>&lt;RDF&gt;
   &lt;Owner Name="me"&gt;
    &lt;has&gt;car&lt;/has&gt;
   &lt;car&gt;
    &lt;has&gt;gpsreceiver&lt;/has&gt;
    &lt;has&gt;&lt;cordinates X="somevalue", Y="somevalue"&gt;&lt;/has&gt;
   &lt;/car&gt;
   &lt;/Owner&gt;
  &lt;/RDF&gt;
  </code></pre>
  
  <p>Is this how it's written? What I have trouble understanding is how subjects, objects and predicates map into elements and attributes.</p>
  
  <p>once I've sorted this out, ultimately I'd like "car" to be its own schema, so I can just refer to its namespace and just say things like "I own car model ABC licence plate DEF that is now at 12.34 coordinates".</p>
  
  <p>Please, please shed some light? At my wits' end and no one around me seems to know rdf or ontologies to enlighten me :-(</p>
