Hi folks,

The OWL 2 working group has recently published last call working  
drafts of a whole slew of things (I include Sandro Hawke's  
announcement below) which cover the entire technical design of the  
language. We also posted first working drafts for some helpful  
documentation. The Primer has not (yet) been updated.

Please review the design! This is the best chance to change it if it  
causes a problem for you or if you spot a bug or if you have an  
*easy* request. The Structural Specification has examples for *every*  
language feature, so is well worth perusing.

Even if you love every last little bit, positive feedback is very  
helpful for determining consensus and moving forward.


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
    2. Direct Semantics
    3. RDF-Based Semantics
    4. Conformance and Test Cases
    5. Mapping to RDF Graphs
    6. XML Serialization
    7. Profiles
    8. Quick Reference Guide
    9. New Features and Rationale
   10. Manchester Syntax
   11. rdf:text: A Datatype for Internationalized Text

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"  
        be a good place to start for many OWL users, these documents  
        be a good place to start.  (A Primer is also being developed,  
        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.
