Audiovisual-based hypermedia authoring - using structured representations for efficient access to av documents.
Résumé
In this article we introduce the notion of audiovisualbased hypermedia authoring systems, i.e. systems mainly using documents from digital audiovisual (AV) archives as a source for hypermedia authoring. After showing that traditional hypermedia models are ill-designed for specific constraints implied by such systems, we propose a change of approach. We present a model based on formal structured representations of the content of documents as it is done in the field of structured documents. Since a specific mode1 for the representation of AV content is needed. we introduce Audiovisual Event Description Inter$ace (AEDI), which provides a model for the description of AV documents. and an XML-based syntax for the exchange of such descriptions. We describe AEDI's main concepts, how it can be related to a formal specification of the domain knowledge -called onrofogy - which allows efficient dynamic hyperlinking among elements. Finally, we describe the implementation of this mode1 for the production of AV based hypermedia at INA's production department.
