The W3C OWL Working Group has just published a set of eleven documents for public review. These documents cover "OWL 2", which is now fairly stable. This is a good time to review this work and send us comments (at public-owl-comments@w3.org). Comments received by 23 January will be answered and taken into account in the next round of publications.
The group expects to issue the OWL 2 Candidatate Recommendations, with a call for implementations, shortly after that comment deadline.
The documents are:
1. Structural Specification and Functional-Style Syntax
http://www.w3.org/TR/2008/WD-owl2-syntax-20081202/
2. Direct Semantics
http://www.w3.org/TR/2008/WD-owl2-semantics-20081202/
3. RDF-Based Semantics
http://www.w3.org/TR/2008/WD-owl2-rdf-based-semantics-20081202/
4. Conformance and Test Cases
http://www.w3.org/TR/2008/WD-owl2-test-20081202/
5. Mapping to RDF Graphs
http://www.w3.org/TR/2008/WD-owl2-mapping-to-rdf-20081202/
6. XML Serialization
http://www.w3.org/TR/2008/WD-owl2-xml-serialization-20081202/
7. Profiles
http://www.w3.org/TR/2008/WD-owl2-profiles-20081202/
8. Quick Reference Guide
http://www.w3.org/TR/2008/WD-owl2-quick-reference-20081202/
9. New Features and Rationale
http://www.w3.org/TR/2008/WD-owl2-new-features-20081202/
10. Manchester Syntax
http://www.w3.org/TR/2008/WD-owl2-manchester-syntax-20081202/
11. rdf:text: A Datatype for Internationalized Text
http://www.w3.org/TR/2008/WD-rdf-text-20081202/
Of these eleven documents:
* The first seven are the core technical specification for OWL 2.
Six of these now at "Last Call". This means the Working Group
believes the design is done and that the only changes going
forward will be editorial, along with certain items highlighted
as "at risk" in the documents. The other one, "RDF-Based
Semantics" (which specifies OWL 2 Full) is expected to proceed
to Last Call shortly.
* The "Quick Reference Guide" and "New Features and Rationale"
will
be a good place to start for many OWL users, these documents will
be a good place to start. (A Primer is also being developed, and
a earlier draft was published, but it has not yet been updated to
account for the current state of the language.)
* "Manchester Syntax" specifies an alternative syntax for OWL
which some users prefer and some tools implement, but which is
not required.
* "rdf:text" specifies an XML datatype (developed jointly with
the RIF Working Group) which provides a way to deal with RDF
language-tagged literal strings without making them be a
special case.
Again, please send comments to public-owl-comments@w3.org by 23 January.
Discussion on either of these lists is fine, but might not be seen by the Working Group.
