W3C and OASIS have published WebCGM 2.0, a new industry standard for technical illustrations in electronic documents. WebCGM, which is widely deployed in the defense, aviation, architecture, and transportation industries, has reached new levels of interoperability thanks to this joint effort between OASIS and W3C. Computer Graphics Metafile, or CGM, is an ISO standard for a tree-structured, binary graphics format that has been adopted especially by the technical industries (defense, aviation, transportation, etc) for technical illustration in electronic documents. As the Web emerged as the environment for sharing and creating documents, it became apparent that the best way to use CGM on the Web needed to be clarified, particularly for interactivity such as hyperlinks and hotspots. 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 also builds upon and extends the graphical and intelligent content of WebCGM 1.0. 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. http://www.oasis-open.org, http://www.w3.org/
