OWL 2 and how to cite it

From korrekt.org

Oct 27 2009. It's done! The OWL 2 Web Ontology Language is a W3C Recommendation. Many OWL tools are already compatible with the new specs, and it is expected that all are transitioning to the newer version. OWL 2 consists of many (13) documents, but it has a short overview document and an extended Primer as entry points.

Thus, only one question is left open: how should you cite the new standard? I recommend the following bibtex entries for the aforementioned references:

@book{owl2-overview,
 author    = {W3C {OWL Working Group}},
 title     = {{OWL~2 Web Ontology Language: Document Overview}},
 publisher = {W3C Recommendation},
 note      = {Available at \url{http://www.w3.org/TR/owl2-overview/}},
 year      = {27 October 2009}
}

@book{owl2-primer,
 editor    = {Pascal Hitzler and Markus Kr\"{o}tzsch and Bijan Parsia and
              Peter F. Patel-Schneider and Sebastian Rudolph},
 title     = {{OWL~2 Web Ontology Language: Primer}},
 publisher = {W3C Recommendation},
 note      = {Available at \url{http://www.w3.org/TR/owl2-primer/}},
 year      = {27 October 2009}
}

Yes, using @book is a good idea here: bibtex recommends picking reference types by appearance, not by name (and there is no @w3cstandard anyway). The other documents can be cited like the Primer (I just use author for the overview since editor would look inappropriate at this place).

Of course you could also cite a textbook on OWL 2 ;-)
