OWL
OWL (Web Ontology Language) is a framework for expressing ontologies for automated reasoning applications. While not strictly subordinate to RDF, OWL has an incarnation as an RDF vocabulary, which is a superset of RDF Schema. In this form, OWL ontologies make it possible to express stipulations of cardinality on properties, term reconciliation and equivalencies between classes and properties, and a number of other desirable capabilities.
