Public Review Draft for WebCGM Version 2.1

Members of the OASIS CGM Open WebCGM Technical Committee have released
"WebCGM Version 2.1" as a Committee Draft for public review. The comment
period ends June 01, 2008. 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 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. The content of the WebCGM 2.1 profile
comprises less than a dozen items that were arguably within the scope
of WebCGM 2.0, but which arose too late in the standardization of the
latter. On 30-January-2007, OASIS and W3C simultaneously published
WebCGM 2.0 as both an OASIS Standard and a W3C Recommendation, which
are identical in all technical aspects, and differ only in the format
and presentation styles of the respective organizations.
