[Draft] Transition REquest to PR

Lofton,
Here is the draft to be sent for Transition to PR.
Have a review and let me know if it is OK with you.

I need your final SOTD update to include at the end of the request.

We should sent it tomorrow, end of day, Boston Time.

This is a request for a Transition to PR.
----------------------------------------

* Title: "WebCGM 2.0"
* URI: http://www.w3.org/TR/2006/PR-webcgm20-20060906/
* Estimated publication date: 20 October Sept 2006
* Document Abstract: see below
* Status section: see below

The PR version is currently available at
http://www.w3.org/Graphics/WebCGM/drafts/PR/Overview.html
and will be moved to its final destination.

* Record of the decision to request the PR Transition:
During its WG F2F meeting, the WebCGM group has resolved to request 
Transition to PR.
[From the Minutes]:

<lofton>
Subject to no further comments by CR close, 6th October, the WebCGM WG 
approves the spec [2] for PR transition and requests the Director to 
approve PR transition.
<lofton> (Don sent email saying that he approves.)
<lofton> No objections?
<lofton> Unanimous.

See
http://www.w3.org/Graphics/WebCGM/WG/Minutes/2006/10/05-webcgm-minutes.html

* Report of important changes to the document:
The changes that this version introduces from the CR version are minor 
changes.
- Added informative Appendix E, "WebCGM accessibility" -- written in 
collaboration with WAI PF
- Added WCAG and UAAG to Chapter 1 References.
- Removed ancient, pre-W3C parts of Change log.

See Appendix D1. Change Log 
http://www.w3.org/Graphics/WebCGM/drafts/PR/WebCGM20-Appendix.html#webcgm_changelog

No features at risk were removed.


* 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 2.0 Requirements at
     http://www.cgmopen.org/technical/WebCGM_20_Requirements.html

* Evidence that dependencies with other groups met (or not):
WebCGM 2.0 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 Last Call period.
See the Disposition of Comments document at
     http://www.w3.org/2006/07/03/WebCGM2-LastCallResponses.html

* Evidence that the document has received wide review:
The specification was reviewed by implementers of the WG and by the 
following organizations:

  - OASIS has reviewed the Last Call version, through their monthly meeting.
  - Peter Zimmermann representing Technical Publication Specification 
Maintenance Group (TPSMG) of ASD, who maintains the S1000D CGM Profile
  has reviewed the LC document.
  - Air Transport Association (ATA) has reviewed the LC document.


* Evidence that issues have been formally addressed.

No comments received during the CR period review.

* 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 2.0 features are implementable 
and are interpreted in a consistent manner. To do so, the Working Group 
will insure that all features in the WebCGM 2.0 specification have been 
implemented at least twice in an interoperable way. This defined this as:
     - the implementations have been developed independently,
     - each test in the WebCGM 2.0 test suite has at least two passing 
implementations.
    2. The Working Group releases a public test suite for WebCGM 2.0 
along with an implementation report."

During the CR period, the WebCGM WG has finalized and released a WebCGM 
2.0 test suite available at
http://www.w3.org/2006/Graphics/WebCGM/testsuite.html

There is already a good amount of products in development implementing 
WebCGM 2.0, from Viewers and Printers Browser plug-ins and standalone 
viewers, Editors, Filters and Converters, WebCGM capable printers, etc.
See http://www.cgmopen.org/webcgm/products.html

There has been an "interoperability day" during the WebCGM WG F2F 
meeting in Köln, Germany,  Aug 23, 24, 25th 2006.
A implementation report with detailed matrix shows which software 
implements each feature of the specification.
See http://www.w3.org/2006/Graphics/WebCGM/implementation-report.html

On October 05th 2006, each test in the WebCGM 2.0 Test Suite has at 
least two passing implementations developed independently. This includes 
the features at risk mentioned in the WebCGM 2.0 CR version. Therefore 
the exit criteria mentioned in the Status of this Document section of 
the WebCGM 2.0 Candidate Recommendation are fulfilled.

* 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

On 22 September 2006, the Working Group received notice of a Patent 
Policy exclusion period to end on 21 November.
The Working Group expected to advance to Proposed Recommendation prior
to that date. Therefore the Group requested to end the exclusion period 
early by securing agreement from all Advisory Committee Representatives 
of Members participating in the WebCGM Working Group.
All Working Group Members have agreed to end the exclusion period that 
began 22 September 2006. All agreed to waive any right to future 
exclusions with respect to the text of the WebCGM 2.0 CR draft.

The result of the Questionnaire for enabling WebCGM WG to end exclusion 
opportunity is available at
   http://www.w3.org/2002/09/wbs/39256/webcgm2006/results

As all participating Members agreed to end the exclusion period, the 
group requests to advance to Proposed Recommendation. The exclusion 
period will end upon approval from the Director to advance to Proposed 
Recommendation.


* Abstract:

Computer Graphics Metafile (CGM) is an ISO standard, defined by ISO/IEC 
8632:1999, for the interchange of 2D vector and mixed vector/raster 
graphics. WebCGM is a profile of CGM, which adds Web linking and is 
optimized for Web applications in technical illustration, electronic 
documentation, geophysical data visualization, and similar fields. First 
published (1.0) in 1999 and followed by a second (errata) release in 
2001, WebCGM unifies potentially diverse approaches to CGM utilization 
in Web document applications. It therefore represents a significant 
interoperability agreement amongst major users and implementers of the 
ISO CGM standard.

WebCGM 2.0 adds a DOM (API) specification for programmatic access to 
WebCGM objects, and a specification of an XML Companion File (XCF) 
architecture, for externalization of non-graphical metadata. WebCGM 2.0, 
in addition, builds upon and extends the graphical and intelligent 
content of WebCGM 1.0, delivering functionality that was forecast for 
WebCGM 1.0, but was postponed in order to get the standard and its 
implementations to users expeditiously.

The design criteria for WebCGM aim at a balance between graphical 
expressive power on the one hand, and simplicity and implementability on 
the other. A small but powerful set of standardized metadata elements 
supports the functionalities of hyperlinking and document navigation, 
picture structuring and layering, and enabling search and query of 
WebCGM picture content.
