Package org.apache.jena.ontology

Provides a set of abstractions and convenience classes for accessing and manipluating ontologies represented in RDF. The two prevalent ontology languages based on RDF are OWL. Since these two languages are similar, this package attempts to present a common set of abstractions, parameterised by vocabularies fot the different languages.

Note: this package primarily seeks to provide easy programmatic access to the terms in the ontologies. The ontology languages have well-defined semantics that provide entailment rules for triples not directly asserted by the ontology. By and large, an inference engine is needed to access these entailed triples, for which several options and an open architecture are provided elsewhere in Jena.
