title: create RDF using defined OWL ontology
body: <p>I'm generating RDF for a database table(s). I generated OWL ontology for the table(s) using Protégé. I want to use this OWL ontology and create the RDF in RDF/XML format for table data using Jena.  I know how to read and write RDF and OWL files into memory to generate Models, and I know how to use Resource, Property, ModelFactory, etc., classes to generate RDF.  What I'm unable to do is use the ontology (OWL file) I generated and create the RDF instances for those OWL class(s). For example:</p>
  
  <p>sample OWL:</p>
  
  
  
  <pre class="lang-xml prettyprint-override"><code>&lt;owl:Class rdf:about="Person"/&gt;
  &lt;owl:Class rdf:about="Animal"/&gt;
  
  &lt;owl:DatatypeProperty rdf:about="salary"&gt;
      &lt;rdfs:domain rdf:resource="Person"/&gt;
      &lt;rdfs:range rdf:resource="&amp;xsd;real"/&gt;
  &lt;/owl:DatatypeProperty&gt;
  </code></pre>
  
  <p>desired RDF:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;Person rdf:about="Jack"&gt;
    &lt;salary&gt;1234&lt;/salary&gt; 
  &lt;/Person&gt;
  </code></pre>
  
  <p>I'm able to generate RDF like this:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;rdf:Description rdf:about="Jack"&gt;
    &lt;ns:salary&gt;2004&lt;/ns:salary&gt;
  &lt;/rdf:Description&gt;
  </code></pre>
