title: Build an OWL file with JENA
body: <p>My work requires a construction of ontologies modules.
  For this I need to construct owl files to contain those ontologies.
  My input is an xml file with parsed and splitted sentences.</p>
  
  <pre><code>&lt;Subject&gt; A tumor &lt;/Subject&gt; 
  &lt;Verb&gt; is &lt;/Verb&gt; 
  &lt;Object&gt; an abnormal growth &lt;/Object&gt; 
  &lt;/sentence&gt; 
  &lt;sentence&gt; 
  &lt;Subject&gt; A kidney tumor &lt;/Subject&gt; 
  &lt;Verb&gt; is &lt;/Verb&gt; 
  &lt;Object&gt; an abnormal growth &lt;/Object&gt; 
  </code></pre>
  
  <p>What I need to do now is:</p>
  
  <ul>
  <li>convert "subject" and "object" into OntClass</li>
  <li>convert "verb" into a transitive property between "obj" and "sub"</li>
  </ul>
  
  <p>I am new on the ontology domain, may be those are basic questions, but I am struggling with the creation of those files, and especially with the transitive property.</p>
  
  <p>Any help is welcome.</p>
