Abstract: Experience with building distance learning applications shows that a clear understanding of the big picture of standardization in this area is a necessary prerequisite for successful use of standards in practical developments. This article presents e-learning standards, standardization activities and organizations, standards-based development practices, and driving forces for improving existing standards and developing new ones. With these resources, educators and Web-based education system developers will have the tips necessary to approach, implement, and reuse a standards-based distance-learning application.

Abstract: This paper presents an ontology-based framework aimed at explicit representation of context-specific metadata derived from the actual usage of learning objects and learning designs. The core part of the proposed framework is a learning object context ontology, that leverages a range of other kinds of learning ontologies (e.g., user modeling ontology, domain ontology, and learning design ontology) to capture the information about the real usage of a learning object inside a learning design. We also present some learner-centered and teacher-centered scenarios enabled by the proposed framework in order to illustrate the benefits the framework offers to these key participants of any learning process. Finally, we demonstrate how two present educational tools (i.e. TANGRAM and LOCO-Analyst) correspond to the proposed architecture
