rdfKey

private com.clarkparsia.empire.SupportsRdfId.RdfKey rdfKey

The RDF identifier of this type. (The types can also be anonymous classes, and therefore they may not have an URI.)

resource

private com.hp.hpl.jena.rdf.model.Resource resource

The Jena resource that defines this type (important for fast access to type information). This field is lazily initialized by getResource(). All accesses to this field should be made via the getResource() method.
