Hello everyone,

The RDF Data Access Working Group is pleased to announce the publication 
of two documents.

1. The SPARQL Query Language for RDF has been published as a Candidate 
Recommendation and the group has issued a call for implementations. The 
group is continuing to complete and refine a test suite, evolving details 
of which can be found at http://www.w3.org/2001/sw/DataAccess/tests/r2 . 
Implementation feedback is welcome at public-rdf-dawg-comments@w3.org, a 
mailing list with a public archive.

   Status of This Document
   -----------------------
   The design has stabilized and the Working Group intends to advance
   this specification to Proposed Recommendation once the exit
   criteria below are met:

    * A test suite gives reasonable coverage of the features of the
      query language.

      Note that the working group has developed a collection of query
      tests in the past, and the group is currently working on
      approving these tests and migrating them to a new location to
      form the basis of an implementation report. This work is still
      in progress.

    * Each identified SPARQL feature has at least two implementations.

    * Relevant media types are registered:

        o The SPARQL Query Language for RDF specification introduces
          one new Internet Media Type. Review has been requested,
          but the types are not yet registered:
            + application/sparql-query: review request of 24 Nov 2005

    * Normative dependencies have been advanced to Proposed
      Recommendation status:
          o XQuery 1.0 and XPath 2.0 Functions and Operators

   This specification will remain a Candidate Recommendation until at
   least 31 August 2007. An implementation report is in progress.

   This specification contains two features at-risk listed both here
   and where the features appear in the specification:

    * The REDUCED feature
    * The allowance of leading digits in prefixed names

   This document was produced by a group operating under the 5
   February 2004 W3C Patent Policy.
      http://www.w3.org/Consortium/Patent-Policy-20040205/
   W3C maintains a public list of any patent disclosures
      http://www.w3.org/2004/01/pp-impl/35463/status
   made in connection with the deliverables of the group; that page
   also includes instructions for disclosing a patent. An individual
   who has actual knowledge of a patent which the individual believes
   contains Essential Claim(s)
      http://www.w3.org/Consortium/Patent-Policy-20040205/
   must disclose the information in accordance with section 6 of the
   W3C Patent Policy.

The Data Access Working Group Working Group expects to receive more
comments in the form of implementation feedback and test cases. The
Working Group believes it will have satisfied its implementation
criteria by 31 August 2007.

This Call for Implementations follows section 7.4.3 of the W3C Process

2. The DAWG has published a Last Call Working Draft of the SPARQL Query 
Results XML Format. This draft differs from the previous Candidate 
Recommendation document in that the previously underspecified and largely 
unused 'distinct' and 'ordered' attributes have been removed.

Status of This Document

This section describes the status of this document at the time of its 
publication. Other documents may supersede this document. A list of 
current W3C publications and the latest revision of this technical report 
can be found in the W3C technical reports index at http://www.w3.org/TR/.

The SPARQL Query Results XML Format is returning to Last Call Working 
Draft for three weeks in order to simplify the specification by 
eliminating the ordered and distinct attributes. This document was 
produced by the RDF Data Access Working Group (part of the Semantic Web 
Activity) for review by W3C Members and other interested parties.

The tests for the SPARQL Query Language for RDF also test the SPARQL Query 
Results XML Format so the Results Format specification will proceed 
directly from Last Call to Proposed Recommendation when SPARQL Query 
proceeds to Proposed Recommendation.

Comments are due by 5 July 2007, to public-rdf-dawg-comments@w3.org, a 
mailing list with a public archive; any resulting issues will be recorded 
in the issues list.

Publication as a Working Draft does not imply endorsement by the W3C 
Membership. This is a draft document and may be updated, replaced or 
obsoleted by other documents at any time. It is inappropriate to cite this 
document as other than work in progress.
