com.hp.hpl.jena.ontology.Individual

Interface that encapsulates an individual in an ontology, sometimes referred to as a fact or assertion, or a member of the a-box. In order to be recognised as an individual, rather than a generic resource, at least one rdf:type statement, referring to a known class, must be present in the model.
