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 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.
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.

This is the First Public Working Draft and a Last Call Working Draft of "WebCGM 2.1".
This WebCGM 2.1 specification is based on a work by the same name, WebCGM 2.1 an OASIS Committee Specification. This initial W3C version of the WebCGM 2.1 specification is substantially identical in technical content to that Committee Specification. The WebCGM 2.1 specification is related to the previous W3C work on WebCGM 1.0 and 2.0. WebCGM 2.0 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. It is agreed that WebCGM 2.1 will be progressed by the same collaborative process and will result in technically a identical Recommendation and OASIS Standard.
