Microsoft Word - Edmedia_2001.doc Using metadata for re-using material and providing user support tools Allard Strijker University of Twente P.O.

This is mainly caused by recent initiatives for standardization of learning technology, but also by the necessity of a more efficient usage of valuable learning resources and development time. Standards for reuse can provide uniform specifications for exchange of learning content. To make reuse efficient, metadata is needed to find and select relevant content. Metadata, information about data, describes this data on a higher level, so that material can be identified, ordered, categorized and selected. However, adding metadata can be very time-consuming. This paper describes a support system for users, like educational developers, teachers and learners, to add metadata to existing learning content and courses. Introduction The faculty of Educational Science and Technology started a faculty wide implementation of Telelearning with the TeleTOP project in 1997. The aim of the project was to support teachers and students with a web based database driven environment. In three years time educational designers created a very large quantity of learning content stored in more then 600 courses. It is very beneficial if this set of learning content could be reused in different courses. Metadata Metadata can be seen as descriptive information; description as in providing more information about data. This is analog to the information such as found in a card index in the library, where information can be found about the stored books. Metadata is used to structure the collection of books. The better the material is organized, the better and faster a useful selection can be made. The themes used in a library (Nature, Science, Sports) are standardized and
