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.
