Aus der Summary des PDF:
OWL is the latest standard in ontology languages (W3C Recommendation
February 2004). It is layered on top of RDF and RDFS, and has a rich set of
constructs. There are three categories of OWL: OWL-Lite, OWL-DL and OWL-
Full. Automated reasoning is possible over ontologies that are written in OWL-
Lite and OWL-DL. OWL brings relationships to RDF. OWL allows individual
instances of classes to be included in the ontology. OWL classes and individuals
can be stored as RDF triples. RDF extends the XML Model and Syntax to be
specified for describing resources. OWL assigns a specific meaning to RDF
Triples. OWL is derived from the DAML + OIL Web Ontology Language and
builds upon the RDF. OWL ontology language differs from an XML schema in
that it is meant for knowledge representation, not for a message formatting. XML
and RDF formats are part of the OWL standard. OWL is useful for various
applications such as knowledge representation, knowledge management, photo
retrieval, access control policies and so on. We may use further rules extension
to OWL i.e. SWRL (Semantic Web Rule Language).
