Abstract [en]

A general SOA framework for Virtual Learning Environments, based on the VWE Learning Object Taxonomy, is suggested in this chapter. Five basic and general services are suggested for implementation of modular Virtual Learning Environments. The design of the service framework was tested by implementation in two prototypes, using two different approaches where a Java-RMI based implementation was compared to a Web Service (SOAP) based implementation. By implementing the VWE Learning Object Taxonomy and the VWE SOA framework, the prototypes showed that a level of modularity, similar to the level of modularity of Learning Objects, could be achieved for the Virtual Learning Environment as well. Using the VWE Learning Object Taxonomy, this was accomplished by including the learning content and the Virtual Learning Environment into the same conceptual space. The comparison of the prototypes showed that the Web Service approach was preferred in favor of the Java-RMI approach. This was mainly due to platform neutrality and the use of the http-protocol. The study was supplemented by an analysis of the two approaches in relation to a third, REST-based approach.
