Reuse of Teaching Materials in Targeteam

Electronic representation of teaching materials enables their reuse for a more efficient development of courses. Most authors consider reuse as a matter of metadata, which describes entities of teaching materials in a way that authors can search and assess the entities before adding them to a course. In this paper we identify two additional requirements for reusable entities: Abstractness and adaptability. We explain, how these requirements are implemented in the Targeteam system, using XML for the representation of abstract entities and using XSLT for their adaptation by transformations.
