Subject: Re: DAGC: WWW Info
Status: RO
The recent mail about WWW and the search for a graphical file format
illustrates a certain lack of awareness of the status and capabilities
of CGM. So far, all of the requirements which have been articulated
are directly met either by CGM:1992 itself, or one of the industry
profiles. Probably, SVF could be defined as a Profile of CGM.
I will address one specific point of misinformation, from the mail dialog...

This is wrong. CGM:1992 Amendment 2 has finished processing, final text
has been reviewed and will soon (already?) go to Geneva. Amd.2 is a simple
addition to the standard to define Application Structures. The purpose of
these (or one purpose) is exactly to enable structuring and hot links.
Products are already being built and sold which use these standard CGM
features!

It is hard to believe that the world needs yet another graphical file
format. Sitting next to me is the 900-page Encyclopedia of Graphical
File Formats, which describes approximately 90 graphics formats.
