<h2><a id="Abstract" name="Abstract">Abstract</a></h2>

<p>CGM (Computer Graphics Metafile) has been an ISO standard for vector and
composite vector/raster picture definition since 1987. It has been a
registered MIME type since 1995. CGM has a significant following in technical
illustration, electronic documentation, geophysical data visualization,
amongst other application areas. WebCGM is a profile for the effective
application of CGM in Web electronic documents. WebCGM has been a joint
effort of the CGM Open Consortium, in collaboration with W3C staff and
supported by the European Commission Esprit project. It represents an
important interoperability agreement amongst major users and implementors of
CGM, and thereby unifies current diverse approaches to CGM utilization in Web
document applications. WebCGM's clear and unambiguous conformance
requirements will enhance interoperability of implementations, and it should
be possible to leverage existing CGM validation tools, test suites, and the
product certification testing services for application to <abbr>WebCGM</abbr>
. While WebCGM is a binary file format and is not "stylable", nevertheless
WebCGM follows published W3C requirements for a scalable graphics format
where such are applicable. The design criteria for the graphical content of
WebCGM aimed at a balance between graphical expressive power on the one hand,
and simplicity and implementability on the other. A small but powerful set of
metadata elements is standardized in WebCGM, to support the functionalities
of: hyperlinking and document navigation; picture structuring and layering;
and, search and query on WebCGM picture content.</p>
<h2><a id="Status" name="Status">Status of This Document</a></h2>

<p>This document has been reviewed by W3C Members and other interested
parties and has been endorsed by the Director as a W3C Recommendation. It is
a stable document and may be used as reference material or cited as a
normative reference 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>

<p>This second release is not a new version of WebCGM (first published 21
January 1999); it merely incorporates the changes dictated by the first
release errata (available at <a href="http://www.w3.org/Graphics/WebCGM-19990121-errata">
http://www.w3.org/Graphics/WebCGM-19990121-errata</a>) as a convenience to the
readers.  The errata list for this second release is available
at <a href="http://www.w3.org/Graphics/WebCGM-20011217-errata">
http://www.w3.org/Graphics/WebCGM-20011217-errata</a>.  Please report errors in
this specification to the <a href="mailto:info@cgmopen.org">WebCGM document editor</a>.</p>
