Hello Laura, Fedora may have more than one ontology, depending on how you look at it. The system creates a graph with it's own predicates representing each object and datastream. There are also a set of Fedora "view" predicates, which are used to indicate disseminations available for an object.
Lastly, there is a sort of default Fedora ontology for defining relationships *between* objects. Some people use this default ontology and other don't. You can create any triple you like in RELS-EXT RDF, as long as the subject is the PID of the object in question. We use SPARQL queries against our Fedora triple store. However, we opted to install Mulgara as a stand-alone application. So we are using the Mulgara SPARQL REST interface. If you use the Fedora-installed Mulgara, then you may have a different endpoint.
