Abstract
This paper introduces an architecture for an e-learning system with an embedded authoring system. Based on the metaphor of a construction kit, this approach offers a general solution for specific content creation and publication. The learning resources are IMS "Content Packages" with a special structure to separate content and presentation. These packages are called "Template Content Objects" (TCO). They contain a template coded in XML and additional files for multimedia learning objects. TCOs are similar to the SCORM "Sharable Content Objects" (SCO) and can be simply translated to them. The authoring system consists of different authoring tools that handle TCOs. Every task in the process of learning object creation is done by experts which were modeled with the help of roles. The architecture is a result of the math-kit, a Web based e-learning system that provides instructors and students with multimedia support for central topics in undergraduate mathematics.
