In this paper, we present our design and implementation of ASIS multimedia digital library. Besides bibliographic information, our service includes an archive of digital audio and video streams, CD titles, and WWW contents. This system not only aims at end customer supports, e.g., searching, streaming, and browsing operations, but it also facilitates admission control, content production, distribution processes, and license control, etc. We address several design issues in designing a multimedia digital library, e.g., the need for accounting support and system management, for integrating third party system components and varied kind of multimedia, and for a computer aided tool to automatically process the backend production. Our solutions to these problems are presented.
