E-learning as a Service: Benefits of the Semantic Web and SOA for Virtual Learning

Despite a growing body of literature in the field, several challenges in designing open educational systems still remain. To achieve desiderata such as openness and flexibility, e learning systems often make use of the semantic web and service oriented architecture (SOA) design principles. This paper offers a brief review of guidelines, standards, tools, and software solutions for the development of semantic web -based e-learning applications or platforms. Potential benefits of integrating additional, less commonly used models and tools are also discussed.
