SUPPORTING THE REUSE OF MULTIMEDIA PRESENTATIONS

We developed an intelligent multimedia presentation design system earl ier. Based on the system, we now develop a multimedia database system that supports the reuse of multimedia presentations and resources. The database consists of two layers: the frame layer and the resource lay er. A frame group in the first layer is the basic presentation unit to be reused. A resource group in the second layer is a collection of re sources to be used by a frame or a frame group. In these two layers, w e use four types of links in the database to group frames and/or resou rces. Also, multimedia resources are associated with a number of prope rties. Using these properties, we allow the user to search for resourc es via a database browser. The database is built on the top of a comme rcial abject-oriented database server and run under a windowing system . (C) Elsevier Science Inc. 1997.
