The Ontology Web Language (OWL) is a set of markup languages which are designed for use by applications that need to process the content of information instead of just presenting information to humans.WL has more facilities for expressing meaning and semantics than XML, RDF, and RDF-S, and thus OWL goes beyond these languages in its ability to represent machine interpretable content on the Web. OWL is part of the W3C recommendations related to the Semantic Web.
