[DRAFT] Transition request to be sent to timbl@w3.org, steve@w3.org,
chris@w3.org, cc'ing w3t-comm@w3.org and chairs@w3.org
Let me know if this document fits you.
----------------------------------------
This is a request for a Transition to CR.
* Title: "WebCGM 2.0"
* URI: http://www.w3.org/TR/2006/CR-webcgm20-20060905/
* Estimated publication date: 5 Sept 2006
* Document Abstract: see below
* Status section: see below
* Record of the decision to request the Transition:
During its WG F2F meeting, the WebCGM group has resolved to request
Transition to CR. See
http://www.w3.org/@@@
* Report of important changes to the document:
The changes that this version introduces from the Last Call Working
Draft are only editorial and minor changes.
See Appendix D. Change Log
http://www.w3.org/TR/2006/CR-webcgm20-20060905/WebCGM20-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 2.0 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:
Last Call Review announcement was sent to the chairs@w3.org list and to
the public-webcgm@w3.org list on Mon, 26 Jun 2006.
We have especially requested review from WGs those listed for
coordination in the WG Charter : Hypertext CG, DOM IG, WAI project,
I18N WG, Web API WG, QA IG. We received responses from I18N WG, Web API
WG, and Steven Pemberton from the Hypertext CG. We have reminded the WAI
project a couple of times.
Review from other organizations:
- OASIS has reviewed the Last Call version, through their monthly meeting.
- Peter Zimermann representing Technical Publication Specification
Maintenance Group (TPSMG) of ASD, who maintain the S1000D Standard
has reviewed the LC document.
- Air Transport Association (ATA) has reviewed the LC document.
* Evidence that issues have been formally addressed.
All comments have been formally addressed.
See the Disposition of Comments document.
http://www.w3.org/2006/07/03/WebCGM2-LastCallResponses.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 2.0 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 defines 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."
The WG expects the CR period to be 1 month (the minimal CR ending date
is set to 05 October 2006). The WG expects Transition to PR early November.
During the CR period, the WebCGM WG will finalize and release a WebCGM
2.0 test suite.
A preliminary WebCGM 2.0 test suite is available at
http://www.w3.org/2006/Graphics/WebCGM/testsuite.html
There is already a good amount of products 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 Koln, Germany, Aug 23, 24, 25th 2006.
A preliminary 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
The Working Group has identify specific features of the technical report
as being "features at risk":
* Pattern Size aspect of definable patterns.
* Performance requirements for Miter limit.
* Text on a path
* 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
* Abstract:
"WebCGM — first published (1.0) in 1999 followed by a second (errata)
release in 2001 — unifies potentially diverse approaches to CGM
utilization in Web document applications, and therefore represents a
significant interoperability agreement amongst major users and
implementers of the ISO CGM standard. WebCGM finds significant
application especially in technical illustration, electronic
documentation, and geophysical data visualization, amongst other
application areas.
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.
* Status section:
"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/.
Publication as a Candidate Recommendation 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.
W3C publishes a Candidate Recommendation to indicate that the document
is believed to be stable and to encourage implementation by the
developer community. The WebCGM Working Group expects to request that
the Director advance this document to Proposed Recommendation when the
following exit criteria have been met:
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 defines 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.
The WebCGM 2.0 test suite will add to the WebCGM 1.0 test suite at least
one test case for any new feature introduced in WebCGM 2.0, covering the
new DOM-related and XCF features, and the new static and "intelligence"
feature.
The Working Group has identified the following features as "at risk". If
not interoperably implemented by the end of the Candidate Recommendation
period, these features will be loosen in the WebCGM Profile of the
Proposed Recommendation version.
* Pattern size aspect of definable patterns.
* Performance requirements for Miter limit.
* Text on a path
This document was developed by the WebCGM Working Group, part of the
Graphics Activity. The Working Group expects to advance this Working
Draft to Recommendation Status. This specification will remain a
Candidate Recommendation until at least 05 October 2006.
This specification is based, in large part, on a work by the same name,
WebCGM 2.0 an OASIS Committee Specification submitted to W3C as WebCGM
2.0 Submission. This Member Submission is related to the previous W3C
work on WebCGM 1.0, and draws on experiences with that format from
implementors and users over five years. This Working Draft incorporates
feedback and discussion following the Submission.
Please send comments on this document to the working group's public
email list public-webcgm@w3.org (public archive). Use "[CR Comment]" in

This document was produced by a group operating under the 5 February
2004 W3C Patent Policy. W3C maintains a public list of any patent
disclosures 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) must disclose the information in accordance
with section 6 of the W3C Patent Policy."
