title: Which RDF formats does GraphDB supports for preserving target graphs?
body: <p>The GraphDB import settings has an option for 'Target graphs' with 3 possible values:</p>
  <ul>
  <li>from data</li>
  <li>the default graph</li>
  <li>a named graph (to be specified)</li>
  </ul>
  <p>There is a tooltip documentation that says:</p>
  <p>Data is imported into one or more graphs. Some RDF formats may specify graphs, while others do not support that. The latter are treated as if they specify the default graph.</p>
  <p>Which RDF formats does GraphDB recognizes for specifying a graph?</p>
  <p>In particular, is Owl serialized in RDF/XML one such format?</p>
  <p>When I import a zip file of multiple *.owl files in RDF/XML format, I get all the triples loaded into the default graph even though I chose the 'from data' import option.</p>
  <p>Can someone explain me how to import ontologies into GraphDB with graphs from the data?</p>
