<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 and
|
|
followed by a <a href="http://www.w3.org/TR/2001/REC-WebCGM-20011217/">second
|
|
(errata) release in 2001</a>, 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>WebCGM 2.0 adds a DOM (API) specification for programmatic access to
|
|
WebCGM objects, and a specification of an XML Companion File (XCF)
|
|
architecture, for externalization of non-graphical metadata. WebCGM 2.0, in
|
|
addition, builds upon and extends the graphical and intelligent content of
|
|
WebCGM 1.0, delivering functionality that was forecast for <a
|
|
href="http://www.w3.org/TR/2001/REC-WebCGM-20011217/">WebCGM 1.0</a>, but was
|
|
postponed in order to get the standard and its implementations to users
|
|
expeditiously.</p>
|
|
|
|
<p>The design criteria for WebCGM aim at a balance between graphical
|
|
expressive power on the one hand, and 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>

|
|
Recommendation</a> published on 17 December 2001 remains a valid

|
specification, primarily to support existing data and applications, use of

WebCGM 2.0 viewers and authoring tools is encouraged.</p>
