Title: ODA-Based Data Modeling in Multimedia Systems
Author: R. G. Herrtwich and L. Delgrossi

Overview:
A multimedia system can handle both discrete media (text, graphics) and continuous media (audio, video). The design of a multimedia system comprises processing and data modeling aspects. In this paper, we are concerned with data modeling only. We present a proposal to extend the ISO Office Document Architecture (ODA) to accommodate continuous media. To provide media flexibility, the needs for new ODA content architectures are identified. To take into account the timing requirements of continuous-media data, attributes for temporal synchronization are introduced for the logical and layout structure of an ODA document. To consider that multimedia information does not only appeal to the sense of vision, the layout structure is extended from two-dimensional visual space to arbitrary "presentation space". In addition, the inclusion of live information and hypertext features into ODA documents is proposed.
