Gasevic, Dragan; Jovanovic, Jelena; Devedzic, Vladan – Interactive Learning Environments, 2007
The paper proposes a framework for building ontology-aware learning object (LO) content. Previously ontologies were exclusively employed for enriching LOs' metadata. Although such an approach is useful, as it improves retrieval of relevant LOs from LO repositories, it does not enable one to reuse components of a LO, nor to incorporate an explicit…
