A Layer-Based Concept for Presentation Systems

Many educational presentation systems have been developed within the last decade and are successfully supporting higher education nowadays. Surprisingly little effort has been made in order to develop concepts on a higher basis than per system and to identify the specific needs for systems of this category. We suggest a layer-based concept for assisting the processing of content supposed to be annotated and presented. Compared to related work, our contribution identifies reoccurring efforts within the development of different systems and presents a very generic and pattern-like solution for their development.
