  <p>I have tried with this code but the getters give me null values. Getting the two individuals by its names, getting the object property and adding them to the model.</p>
  
  <pre class="lang-java prettyprint-override"><code>Individual doc = model.getIndividual("n6356");
  Individual ref = model.getIndividual("n6399");
  ObjectProperty cites = model.getObjectProperty("http://purl.org/ontology/bibo/cites");
  model.add(doc,cites,ref);
  </code></pre>
