Learning Technologies and Semantic Integration of Learning Resources

Nowadays, virtual learning environments are developed as digital ecosystems based on existing resources, applications, and web services. Even if they are not hosted in a centralized course management system, they are usually highly coupled. In this paper, we show how semantic technologies can help decoupling them. We build an e-learning web ecosystem enriched with an educational information according to an educational information model and a domain-specific model, so we provide teachers and students with a common user interface. We implemented our proposal in the ASCETA project, integrating well-known open-source systems, such as wikis, blogs, microblogging services, content management systems, and task management systems.
