com.hp.hpl.jena.ontology.OntProperty

Interface encapsulating a property in an ontology. This is an extension to the standard {@link Property} interface, adding a collection of convenience methodsfor accessing the additional semantic features of properties in OWL and RDFS such as domain, range, inverse, etc. Not all such capabilities exist in all supported ontology languages.
