This Working Group is now Closed. For more information on OWL, related tools, etc, you may want to consult the OWL page of the Semantic Web Wiki
The Working Group produced OWL 2, a W3C Recommendation that refines and extends OWL, the Web Ontology Language
The OWL Web Ontology Language is designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL facilitates greater machine interpretability of Web content than that supported by XML, RDF, and RDF Schema (RDF-S) by providing additional expressive power along with a formal semantics.
The group's work is complete with the publication of OWL 2 (Second Edition). There may be new Errata and discussion on email@example.com.
- All Working Group participants are automatically subscribed to the group's main discussion list firstname.lastname@example.org (public archive). Non-participants may not subscribe to or post to the list, but they may read the archives on the web archive (including using the RSS feed of the archives).
- The group will also use the Member-confidential administrative list, email@example.com (member-visible archive).
- Comments from the public to the Working Group are welcome at firstname.lastname@example.org (public archive).
- The OWL Working group is part of the W3C Semantic Web activity
