MATILDA Data Model and its Implications

Present authoring issues, such as managing large-scale complexity, information reuse and application maintainability have yet to be effectively addressed by current authoring approaches. This problem has motivated the MATILDA hypermedia project, which has three primary development areas; frameworks, information models, and process models. This paper presents the MATILDA information model. This has been developed within the context of an information management paradigm defined by the MATILDA framework. We discuss the problems and issues associated with hypermedia authoring of large scale applications. We then present our information model and the visual formalism (based on structured graphs) which we have adapted as a foundation for the model. We also show how this information model can assist us in addressing many of the issues raised.
