The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies. The languages are characterised by formal semantics and RDF/XML-based serializations for the Semantic Web. OWL is endorsed by the World Wide Web Consortium (W3C) and has attracted academic, medical and commercial interest.
In October 2007, a new W3C working group was started to extend OWL with several new features as proposed in the OWL 1.1 member submission. W3C announced the new version of OWL on 27 October 2009. This new version, called OWL 2, soon found its way into semantic editors such as Protégé and semantic reasoners such as Pellet, RacerPro, FaCT++ and HermiT.
The OWL family contains many species, serializations, syntaxes and specifications with similar names. OWL and OWL2 are used to refer to the 2004 and 2009 specifications, respectively. Full species names will be used, including specification version (for example, OWL2 EL). When referring more generally, OWL Family will be used.

Famous quotes containing the words web and/or language:
“If our web be framed with rotten handles, when our loom is well nigh done, our work is new to begin. God send the weaver true prentices again, and let them be denizens.”
—Elizabeth I (1533–1603)
“This Light inspires, and plays upon
The nose of Saint like Bag-pipe drone,
And speaks through hollow empty Soul,
As through a Trunk, or whisp’ring hole,
Such language as no mortal Ear
But spiritual Eve-droppers can hear.”
—Samuel Butler (1612–1680)
