A hypertext based product catalog is an electronic extension of a companies paper bound product catalog. Product catalogs are evolving towards full multimedia representations of the products with the ability to search and view 3-D animation, videos and audio related to the products in addition to providing group communications where customers can exchange views on a product they purchased. The aim of this project is to provide a platform for integrating interoperable full multimedia digital catalogs that can be seen as a distributed virtual mall.
Creation of appropriate educational content is a major challenge and cost factor in the increasing important areas of on-line and life-long learning. The aim of the ongoing Courseware-on-Demand project is to enable the creation of course content by recomposing parts extracted from existing annotated course materials. Course materials comprising a variety of learning objects (slides, video, audio, textbook, etc.), are gathered, decomposed into elementary learning fragments, appropriately annotated, indexed, and stored. They are further augmented with course structures and dependencies (prerequisite and precedence). A course designer who has a particular training goal in mind can pose a query to the Courseware-on-Demand system, expressing that goal. The first step in processing the query is to locate course fragments containing material relevant to the goal. Then, taking into account the dependencies, the system can define a minimal path in the metadata network that leads to the goal. The last step is to physically extract the parts of the course materials retrieved during the previous step, and compose the new teaching material or propose a training schedule (temporal ordering) on top of an existing course curriculum.
