WebCGM -- first published (1.0) in 1999 followed by a second (errata) release in 2001 -- unifies potentially diverse approaches to CGM utilization in Web document applications, and therefore represents a significant interoperability agreement amongst major users and implementors of the ISO CGM standard. WebCGM finds significant application especially in technical illustration, electronic documentation, and geophysical data visualization, amongst other application areas.
WebCGM 2.0 adds a DOM specification (API) 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 WebCGM 1.0, but was postponed in order to get the standard and its implementations to users timely.
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.
Originating from collaboration between the CGM Open Consoritium and W3C Graphics Activity, WebCGM satisfies many of the published W3C requirements for an XML-based scalable graphics format, even though it is a binary format.
This is the (second) Committee Draft of WebCGM 2.0, developed and published by the OASIS CGM Open WebCGM TC. It includes all of the reviews and issues resolutions since the first publication of WebCGM 2.0 as an OASIS Committee Draft, March 2005. It includes all substantive changes resulting from the San Francisco editors meeting (11-13 July 2005). See the Change Log for details. There are some minor editorial issues yet to be fixed -- e.g., improvement of picture quality, improvement and addition of examples, etc. Such items are highlighted and styled like this.
This specification has been developed within the OASIS CGM Open WebCGM TC. An addendum to the existing WebCGM 1.0 test suite has been built, with new test cases aimed at all of the principal new functional features of WebCGM 2.0. Implementations are in progress.
