(1) (Web Ontology Language) Extensions to the RDF language used to describe data on the Web. OWL provides a formal description of the meaning of the terminology used. Every OWL document is an RDF document. However, "OWL Full" documents are supersets of RDF, while "OWL Lite" and "OWL DL" (description logistics) are subsets. Why Isn't W-eb O-ntology L-anguage WOL? Because OWL sounds better and is also reminiscent of William A. Martin's One World Language project of the 1970s. OWL was developed to provide one description language for the World Wide Web. See RDF and SPARQL.
