[4th DRAFT] Transition request for 2.1 CR

[4th DRAFT]  Transition request for 2.1 CR to be sent to  timbl@w3.org,
ralph@w3.org, chris@w3.org, cc'ing w3t-comm@w3.org and chairs@w3.org

I have incorporated all of the new information from yesterday, and cleaned 
up the language in a few places.  I have also uploaded the updated snapshot 
of the implementation status.  There are no more "TBD" for this draft 
Transition Request, and I am done with this document for now.

Over to you,
-Lofton.

----------------------------------------

This is a request for a Transition to CR.

* Title: "WebCGM 2.1"
* URI: http://www.w3.org/TR/2009/CR-webcgm21-200909010/
* Estimated publication date: 10 Sept 2009
* Document Abstract: see below
* Status section: see below

* Record of the decision to request the Transition:
During its WG F2F meeting in Ann Arbor - MI - USA, the WebCGM group has 
resolved to request Transition to CR. See
       http://www.w3.org/Graphics/WebCGM/WG/2009/08/26-webcgm-minutes-F2Fd3.html

* Report of important changes to the document:

The WebCGM WG has released two Last Call Working Drafts:
- a WebCGM 2.1 (First public and Last Call Working Draft) [17 September 2008]
http://www.w3.org/TR/2008/WD-webcgm21-20080917/

followed by a WebCGM 2.1 (second public Working Draft) [30 january 2009]
http://www.w3.org/TR/2009/WD-webcgm21-20090130/
incorporating requests for changes from comments sent during the first Last 
Call Review, as agreed with the commenters (see Disposition of Last Call 
comments for WebCGM 2.1).

- a WebCGM 2.1 (second Last Call Working Draft) [04 June 2009]
http://www.w3.org/TR/2009/WD-webcgm21-20090604/
incorporating requests for changes from comments sent during the first Last 
Call Review, as agreed with the commenters and changes following 
implementation experiences from the Working Group.

The changes that this version introduces from the Second Last Call Working 
Draft and previous drafts are available at Appendix D. Change Log.

http://www.w3.org/TR/2009/WD-webcgm21-20090604/WebCGM21-Appendix.html#webcgm_changelog

* Evidence that the document satisfies group's requirements:
The group's initial requirements have not changed. The WG has fulfilled all 
requirements. See initial WebCGM 2.1 Requirements at
       http://www.w3.org/2007/WebCGM21-requirements.html

* Evidence that dependencies with other groups met (or not):
WebCGM 2.1 has no normative references to W3C specifications that are not 
yet Proposed Recommendations. Dependencies with other groups have been 
explored and ensuing issues resolved during the First and Second Last Call 
period. See the Disposition of Comments document at
       http://www.w3.org/Graphics/WebCGM/WG/2008/WebCGM21-LC-comments.html

* Evidence that the document has received wide review:
Last Call Review announcement was sent to the chairs@w3.org list and to the 
public-webcgm@w3.org list on 18 Sep 2008 for the first last Call
http://lists.w3.org/Archives/Public/public-webcgm/2008Sep/0000.html
and on 04 June 2009 for the second last Call.
http://lists.w3.org/Archives/Public/public-webcgm/2009Jun/0000.html

We have especially requested review from WGs those listed for coordination 
in the WG Charter :  I18N WG, SVG WG and SYMM WG.
http://www.w3.org/2007/10/webcgm-charter.html

We received comments from the I18N WG and from individuals.

Review from other organizations:
    - OASIS has reviewed the Second Last Call Working Draft version, 
through their regular meetings, and has monitored preceding drafts as well.
    - WebCGM 2.1 requirements and technical solutions implemented in the LC 
document have been reviewed and validated by the ASD Electronic 
Publications Working Group (EPWG), and the Multimedia Task Team (MMTT).
    - WebCGM 2.1 requirements and technical solutions implemented in the LC 
document have been reviewed and validated by the ATA Graphics & Multimedia 
Project Team (GMPT) through technical presentations.

* Evidence that issues have been formally addressed.
All comments have been formally addressed.  See the Disposition of Comments 
document.
      http://www.w3.org/Graphics/WebCGM/WG/2008/WebCGM21-LC-comments.html

* Objections:
No objections have been received.

* Implementation information:

The CR exit criteria, as decided by the group and mentioned in the 
specification, are:

" 1. Sufficient reports of implementation experience have been gathered
to demonstrate that the WebCGM 2.1 features are implementable and are
interpreted in a consistent manner. To do so, the Working Group will
insure that all features in the WebCGM 2.1 specification have been
implemented at least twice in an interoperable way. This defines this as:
       * the implementations have been developed independently,
       * each test in the WebCGM 2.1 test suite has at least two passing
implementations.

2. The Working Group has adopted  a public test suite for WebCGM 2.1 and 
has produced an implementation report."

A preliminary WebCGM 2.1 test suite is available at
http://www.w3.org/Graphics/WebCGM/2009/WebCGM21/testsuite21.html

A list WebCGM products handling all versions (1.0 & 2.0 also) -- standalone 
Viewers and Printers, Browser plug-ins, Editors, Filters and Converters, 
etc. -- is available at
http://www.cgmopen.org/webcgm/products.html

There is already a fair amount of implementation of WebCGM 2.1.  There were 
several "interoperability sessions" during the WebCGM WG F2F meeting in Ann 
Arbor, MI, USA 24-26 August 2009.
A preliminary implementation report with detailed matrix shows which 
software implements each feature of the specification.  See
http://www.w3.org/Graphics/WebCGM/2009/WebCGM21/implementation-report.html

The WG expects the CR period to be 1 month (the minimal CR ending date is 
set to 10 October 2006). The WG expects Transition to PR early November.

The Working Group has identified specific features of the technical report 
as being "features at risk":
           * XCF access to the new 2.1 Style Properties
           * XCF access to the new 2.1 transform functionality
           * ACI access to Line Type Continuation
           * ACI access to Edge Type Continuation
           * ACI access to Hatch Style Definition
           * ACI access to Line and Edge Type Definition

* Patent Disclosures:
No patent disclosures have been made for any specifications of this 
group.  See WebCGM WG Patent Policy Status
         http://www.w3.org/2004/01/pp-impl/39256/status
