Development of a Multimedia Archiving Teleservice Using the DFR Standard

In this paper, we describe the development of an archiving system according to the BERKOM teleservice “Multimedia Archiving” defined recently. This teleservice is utilized for storage and retrieval of multimedia documents. It can be exploited in applications that require document pools, information services, and workflow management. As a basis of our system we use the ISO/IEC standard “Document Filing and Retrieval (DFR)”. We have chosen the following approach for the integration of multimedia documents within the DFR environment. (1) A specific attribute for DFR-Documents is introduced to model multimedia documents. (2) A dual stack is used separating transmission of discrete data and continuous data like audio and video. An architecture based on this solution is outlined. Especially, the usage of an object-oriented database management system for the storage of multimedia documents is motivated. As an application scenario we describe a multimedia calendar of events.Finally, we evaluate our concepts and describe further developments.
