Refining the MATILDA multimedia authoring framework with a visual formalism

The MATILDA multimedia authoring system has been developed to address issues related to authoring process and information management and representation. The 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.
