Virtual Communities Adapted to the EHEA in an Enterprise Distance e-Learning Based Environment

This paper describes the e-learning architecture of the National Spanish Distance Learning University of Spain (UNED). The UNED has more than 200,000 users of e-learning systems (most of them, students) so it needed an enterprise architecture in order to ensure the performance of the virtual campus. The core of virtual campus is aLF (active learning framework) supported by dotLRN/OpenACS open source framework that provides the e-learning core services. aLF is was modified to support the EHEA learning model, based in activity curricula, providing full integration with the evaluation model of aLF and three new tools to focus on the student tasks planning.
