<h2><a id="abstract" name="abstract">Abstract</a></h2>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>
|
|
|
|
<p>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.</p>

<p>The original Recommendation document (dated 01 March 2010) was updated on 24

august 2010. Wrong links in the following Table of Content and in the above

non-normative formats (zip file<a

<p>WebCGM 2.1 is related to the previous W3C work on WebCGM 1.0 and 2.0. <a
|
|
href="http://www.w3.org/TR/2007/REC-webcgm20-20070130/">WebCGM 2.0</a> 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.</p>
|
|
|
|
<p>This WebCGM 2.1 specification was initially based on a work by the same
|
|
name, <a
|
|

|
<p>This document has been reviewed by W3C Members, by software developers, and
|
|
by other W3C groups and interested parties, and is endorsed by the Director as
|
|
a W3C Recommendation. It is a stable document and may be used as reference
|
|
material or cited from another document. W3C's role in making the
|
|
Recommendation is to draw attention to the specification and to promote its
|
|
widespread deployment. This enhances the functionality and interoperability of
|
|
the Web.</p>
