Refining the MATILDA Multimedia Authoring Framework with a Visual Formalism

The MATILDA multimedia authoring framework has been developed in an attempt to address a number of issues related to authoring process, information reuse and application maintainability. In particular, the framework addresses information representation and usage issues, and has been used in the development of a series of data models. This paper presents our initial application of the structured graph visual formalism to the MATILDA data models. This has resulted in the introduction of a new group of automatically derivable links in the data models, and highlights some data model distinctions which we believe should be captured. We also discuss the possible use of the scalable editing and browsing operations that are part of the formalism.
