OWL

Draft

Definition

• The OWL Web Ontology Language is intended to be used when the information contained in documents needs to be processed by applications, as opposed to situations where the content only needs to be presented to humans.

• OWL is an XML application, i.e. a vocabulary extension of RDF and it is seen as major element of the semantic web framework.

• “The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional vocabulary along with a formal semantics.
