OASIS CGM Open WebCGM Technical Committee

OASIS TC Call For Participation: CGM Open WebCGM TC

Subject:   OASIS TC Call For Participation: CGM Open WebCGM TC
From:      "Karl F. Best" <> 
Date:      Fri, 09 Apr 2004 10:17:35 -0400

A new OASIS technical committee is being formed. The OASIS CGM Open WebCGM Technical Committee has been proposed by the following members of OASIS: Dave Cruikshank, The Boeing Company; Dieter Weidenbruck and Benoit Bezaire, ITEDO Software GmbH; Franck Duluc, Airbus France; Ulrich Laesche, Ematek GmbH; Don Larson, Larson Sofware Technology, Inc; Forrest Carpenter, System Development, Inc; Andrew Moorhouse, MOD UK; Kevin O'Kane, Auto-trol Technology; and Gabriella Rist, Lofton Henderson, and Bruce Garner, Individual members.

The proposal for a new TC meets the requirements of the OASIS TC Process (see, and is appended to this message. The TC name, statement of purpose, scope, list of deliverables, audience, and language specified in the proposal will constitute the TC's charter. The TC Process allows these items to be clarified (revised); such clarifications (revisions), as well as submissions of technology for consideration by the TC and the beginning of technical discussions, may occur no sooner than the TC's first meeting.

As specified by the OASIS TC Process, the requirements for becoming a member of the TC at the first meeting are that you must 1) be an employee of an OASIS member organization or an Individual member of OASIS; 2) notify the TC chair of your intent to participate at least 15 days prior to the first meeting; and 3) attend the first meeting of the TC. For OASIS members, to register for the TC using the OASIS collaborative tools, go to the TC's public web page at and click on the button for "Join This TC" at the top of the page. You may add yourself to the roster of the TC either as a Prospective Member (if you intend to become a member of the TC) or an Observer. A notice will automatically be sent to the TC chair, which fulfills requirement #2 above.

OASIS members may also join the TC after the first meeting. Note that membership in OASIS TCs is by individual, and not by organization.

Non-OASIS members may read the TC's mail list archive, view the TC's web page, and send comments to the TC using a web form available on the TC's web page; click the "Send A Comment" button. The archives of the TC's mail list and public comments are visible at

CGM Open WebCGM TC Charter

Name of the TC

OASIS CGM Open WebCGM Technical Committee

Statement of Purpose

The CGM Open WebCGM TC is chartered to carry out the technical work of the OASIS CGM Open Member Section. That technical work originated with the technical agenda of the former CGM Open Consortium Inc, which since January 2004 has been reorganized and integrated into OASIS as the OASIS CGM Open Member Section.

The purpose of the CGM Open WebCGM TC is to accelerate the further adoption, application, and implementation of the Computer Graphics Metafile (CGM), the international standard for open interchange of structured graphical objects and their associated attributes. The WebCGM Profile of CGM was developed by CGM Open and is a current recommendation of the W3C. WebCGM is focused on presenting dynamic technical graphics in the web environment.

The focus of the TC is to coordinate WebCGM with other CGM application areas, further develop the WebCGM profile based on requirements for needed features, educate users in the appropriate use of CGM and WebCGM, and promote interoperability of CGM and especially WebCGM applications.

At the highest level the problem being addressed by the TC is the improved penetration of CGM and WebCGM into their target application sectors and the successful implementation of multiple interoperable applications in those sectors.


The following is a master list of potential work items that have been enumerated for the CGM technical program. This forms the scope for the CGM Open WebCGM TC:

  • WebCGM future development including possible releases of new versions of WebCGM
  • WebCGM DOM development
  • Web-based CGM interoperability reporting and tracking system
  • Any additional interoperability topics that are identified by the TC in response to the evolution of the markets, target application sectors, and CGM/WebCGM implementations
  • Alignment of WebCGM functionality with ATA (and other) graphics profile requirements
  • Maintenance of product ICS (Implementation Conformance Statement) database
  • Definition of semantics of XML companion data associated with WebCGM
  • XML encoding of WebCGM
  • An education program for users and implementers of CGM and WebCGM technology

In addition, the CGM Open WebCGM TC will maintain relationships with other international standards groups involved in CGM and web graphics technology.

Anything other than the above listed items is considered out of scope for the CGM Open WebCGM TC. There will be significant milestones with the completion of specifications dealing with WebCGM, as well as with the delivery of tools and services for interoperability.

List of Deliverables

In the CGM community there is general agreement about the prioritization of three badly needed, partially finished work items to address the short-term requirements. The following is a list of the three highest-priority, most critical items, from the larger set identified in the above Scope section:

  • WebCGM DOM specification: final design at first F2F meeting with formal DOM acceptance six months later
  • Interoperability reporting/tracking system: public availability one month after first F2F meeting
  • Refresh of product ICS database: one month after first F2F meeting

Additional deliverables are anticipated to satisfy the other identified scope items described above. Those deliverables will be defined and added to the TC's charter upon completion of the currently defined deliverables.

Anticipated Audience

The anticipated audience for this work are vendors and users of web-based technical graphics.



Additional Information

The following is informational only for the purposes of starting the TC, and will not be part of the TC's charter.

Similar Work

The W3C SVG (Scalable Vector Graphics) working group has developed a W3C recommendation for an XML encoded 2D graphics language for web applications. The intended audience for SVG, according to the W3C, is quite different than that of WebCGM. The CGM Open TC will maintain a liaison relationship with SVG through common membership and has considered a mapping of WebCGM functionality to an SVG subset.

List of Contributions

The proposers anticipate that at or after the first meeting of the TC the customization layer of the Web interface problem reporting and tracking system developed by CGM Open Inc., and based on the open source Mantis software, will be contributed to the TC by its owners.

First Meeting

Date: 24-27 May 2004
Time: 9:00 AM CET
Type of meeting: F2F
Location: Cologne, Germany
Sponsor: ITEDO

Ongoing Schedule

There will be monthly telecons hosted by Boeing, and two or three f2f meetings per year hosted by TC members on a rotating basis.
