Meta-Data and Media Management in a Multimedia Interactive Telelearning System

This paper describes the system design and the components of a web-based multimedia interactive Telelearning system (MITS) with emphasis on metadata and media content management mechanisms. Metadata model is defined and exploited in designing the overall architecture to support courseware creating, management, delivery, and learner performance evaluation. Multimedia document architecture is used to describe the media contents which represent the course material. Metadata and media contents are generated, stored, and utilized to facilitate the search and on-demand presentation of learning objects. Learner preference, performance and progress information is maintained by profile database to make courseware presentation adaptable and more interactive. The system provides a multimedia interactive learning environment with easy-to-search and highly reusable learning objects.
