Item GraSSML: Smart Schematic Diagrams, XML and Accessibility(The Eurographics Association, 2006) Fredj, Z. Ben; Duce, D. A.; Louise M. Lever and Mary McDerbyThis paper describes work in progress at Oxford Brookes University. The project called Graphical Structure Semantic Markup Languages (GraSSML) aims at defining higher-level diagram description languages for the World Wide Web, which capture the structure and the semantics of a diagram and enable the generation of accessible and "smart" presentations in different modalities such as speech, text, and graphics. GraSSML is broken down into three levels: semantics, structure and presentation. Each of these levels captures a specific aspect of a diagram. The semantic level language is highly dependent on the type of diagram considered and the knowledge of the domain (ontology) in which it is used. Using the proposed approach, the structure and the semantics of the diagram is made available at the creation stage. The availability of this information offers new possibilities allowing Web Graphics to become "smart". The paper outlines the relevant limitations of SVG and some approaches aiming to resolve the problem of graphic accessibility. It then describes our approach in addressing some of these limitations and presents the new possibilities that these smart graphics lead to.
