Abstract

The CGM Open Consortium is made up of CGM technology vendors, users, and standards participants. Working with W3C graphics resources, the CGM Open Consortium developed the WebCGM Profile as an approved W3C Recommendation in 1999. Since that time several CGM products have appeared making use of WebCGM to deploy interactive graphics in the Web environment. The interoperability of WebCGM has been demonstrated several times by the vendors involved in CGM Open. Recently, DOM functionality has been demonstrated by these vendor products and, the CGM Open Technical Committee initiated a project to standardize this functionality through the development of a DOM. The development of a WebCGM DOM represents a breakthrough in externally and interactively controlling the behavior of CGM V4 application structures and graphical primitives via the JAVA binding of IDL (Interface Definition Language). The object model in WebCGM describes various non-graphical attributes that are associated with application structures. The ability to control the values associated with these attributes facilitates reuse of CGM graphics in different contexts. The CGM standard defines various control and attribute elements associated with graphical primitives. The ability to control the values of these elements facilitates the graphical styling of the graphical primitives and enables cleaner interactive feedback to the user interface.
