Originally published as a PhD thesis, Distributed Architectures for Laboratory-Based E-Learning describes research on resource access management in the Internet, proposes novel architecture and didactical frameworks for resource access management, and distributes those plans and didactics. These concepts have been practically implemented in geographically distributed international e-learning projects about computer science. The Distributed Architectures of the title allow multiple organizations in many places to use the Internet to implement a common e-learning course not limited to computer science topics. This open architecture solves generic authentication and authorization issues and gives access to distributed hands-on e-learning laboratories. Also described is a didactical concept which is necessary if many different organizations produce content modules for one common course.
