OWL 2 Last Call Documents Published
by Kendall Clark
Today the W3C announced the publication of the OWL 2 Last Call Documents—11 in total!—which begins the period of open, public comment, during which anyone can make comments and file questions about the documents that specify OWL 2, the first major revision of the W3C’s Web Ontology Language.
I encourage Pellet users and other OWL users to review the documents, one or several of them, and provide feedback to the WG so that OWL 2 can move to recommendation status as soon as possible.
Congratulations to all on the OWL WG who’ve worked so hard to get this far, this fast (and, if you haven’t done a lot of standards work, trust me: they’ve done a ton of work very quickly, all things being equal), and I especially want to thank Mike Smith, who’s been the C&P representative on the OWL WG, and also Bijan Parsia for all their hard work in bringing OWL 2 to this stage.
Finally, I’ll point out that the OWL 2 Profiles document is especially noteworthy for us since it describes subsets of OWL 2, several of which we provide tools for:
- Pellet 2.0 RC3 contains an optimized reasoner for OWL 2 EL, an OWL 2 profile
- Owlgres contains an optimized reasoner for OWL 2 QL (well, for a very closely related Description Logic, but with different syntax, so we’ll be updating Owlgres to fix these details as soon as the OWL 2 docs are formally standardized).
