Editing Web Ontology Language (section)

====OWL Working Group====
In 2005, at the ''OWL Experiences And Directions Workshop'' a consensus formed that recent advances in description logic would allow a more expressive revision to satisfy user requirements more comprehensively whilst retaining good computational properties.
In December 2006, the OWL1.1 Member Submission<ref name="owl1.1">{{cite web |url=http://www.w3.org/Submission/2006/SUBM-owl11-overview-20061219/ |title=OWL 1.1 Web Ontology Language |last1=Patel-Schneider |first1=Peter F. |author-link1=Peter F. Patel-Schneider |last2=Horrocks |first2=Ian |date=2006-12-19 |publisher=World Wide Web Consortium |access-date=26 April 2010 }}</ref> was made to the W3C. The W3C chartered the ''OWL Working Group'' as part of the Semantic Web Activity in September 2007. In April 2008, this group decided to call this new language OWL2, indicating a substantial revision.<ref name="grau.2008">{{Cite journal | last1 = Grau | first1 = B.

OWL 2 became a W3C recommendation in October 2009. OWL 2 introduces profiles to improve scalability in typical applications.<ref name="w3.org" /><ref name="owl2-profiles"/>
