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

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.


    OntModel model = ModelFactory.createOntologyModel( PelletReasonerFactory.THE_SPEC );


    // add one instance relation
    OntClass cls = model.createClass( ns + "C" );
    Individual a = model.createIndividual( ns + "a", cls );


    // load everything and check consistency
    assertTrue( model.validate().isValid() );


    // add a type relation for an existing individual
