com.hp.hpl.jena.ontology.OntModel.createIndividual()

Answer a resource that represents an Individual node in this model. A new anonymous resource will be created in the writable sub-model of the ontology model.
@param cls Resource representing the ontology class to which the individual belongs @return A new anonymous Individual of the given class.

    Individual bob = model.createIndividual( ns + "bob", HomeOwner );
    ObjectProperty hasNeighbor = model.createObjectProperty( ns + "hasNeighbor" );
    OntClass NeighborOfBob = model.createClass( ns + "NeighborOfBob" );
    NeighborOfBob
        .addEquivalentClass( model.createHasValueRestriction( null, hasNeighbor, bob ) );
    Individual susan = model.createIndividual( ns + "susan", HomeOwner );
    susan.setPropertyValue( hasNeighbor, bob );
    // model.write(System.out, "RDF/XML-ABBREV");


    assertTrue( "susan is not a NeighborOfBob", susan.hasRDFType( NeighborOfBob ) );
