Dear chairs and colleagues,

The WebCGM WG has published WebCGM 2.1 to a First Public and Last Call
Working Draft on September 17th 2008.

Latest version:

Previous version:
This is the first version.

Instructions for providing feedback

The Last Call review period of approximately 6 weeks, is ending on *01 
November 2008*.
Comments must be sent to the <public-webcgm@w3.org> mailing list (public 
archive). Use "[LC Review]" in the subject line of your email.

The WebCGM WG Charter [1] mentions following dependencies with other 
working groups:

* Internationalization Core Working Group
* Synchronized Multimedia Working Group
* Scalable Vector Graphics Working Group

Note that the Charter identifies the principal dependency with SVG and 
SMIL  as concerning (declarative) animation, which is effectively a 
"MAY" in the requirements ([2]).  It is now dropped from the scope of 
2.1. The WebCGM WG of course still welcomes input from all groups.

The Last Call review focuses only on the new features that WebCGM 2.1 
adds to WebCGM 2.0.

For your convenience, the document shows the new features that WebCGM 
2.1 adds, using:
- a section summarizing and pointing to the new functionality in WebCGM 
2.1 [3];
- a changeLog listing in detail all significant text changes since 
WebCGM 2.0 [4].
- throughout the specification, the new features that WebCGM 2.1 adds to 
WebCGM 2.0 are highlighted using a style with an ocre background and red 
border.(see example for [3]).

Document Abstract and Status


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, 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.

The design criteria for WebCGM aim to balance graphical expressive power 
on the one hand, versus 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.

The present version, WebCGM 2.1, refines and completes the features of 
the major WebCGM 2.0 release. WebCGM 2.0 added a DOM (API) specification 
for programmatic access to WebCGM objects, a specification of an XML 
Companion File (XCF) architecture, and extended the graphical and 
intelligent content of WebCGM 1.0.

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 

This is the First Public Working Draft and a Last Call Working Draft of 
"WebCGM 2.1".

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 WebCGM 2.1 specification is based on a work by the same name, 
WebCGM 2.1 an OASIS Committee Specification. This initial W3C version of 
the WebCGM 2.1 specification is substantially identical in technical 
content to that Committee Specification. The WebCGM 2.1 specification is 
related to the previous W3C work on WebCGM 1.0 and 2.0. WebCGM 2.0 was 
simultaneously published by W3C as a Recommendation and by OASIS as an 
OASIS Standard. The two versions are identical in technical content, 
differing only in the formatting and presentation conventions of the two 
organizations. It is agreed that WebCGM 2.1 will be progressed by the 
same collaborative process and will result in technically a identical 
Recommendation and OASIS Standard.

The W3C Membership and other interested parties are invited to review 
the document and send comments through 01 November 2008. Comments must 
be sent to the public-webcgm@w3.org mailing list (public archive). Use 
"[LC Review]" in the subject line of your email.

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.

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.
