title: Loading an ontology (owl) using jena and show its graph
body: <p>Im working in a project where I have to load any ontology (is chosen by the user) in .owl language and display its graph as a tree menu. It means the ontology can be any size.</p>
  
  <p>The goal is to show a Taxanomy to be able to classify learning objects.</p>
  
  <p>At the moment, using jena I can load the ontology, but I wonder how to show the graph in a proper way to build the tree menu.</p>
  
  <p>Thanks</p>
