Domain Ontologies Integration into the Learning Objects Annotation Process

Abstract. This paper describes an extension of the LOM metadata elements used in the IMS learning object speci-fications, to incorporate new labels for the semantic classification of non-educational information to the set of LOM metadata. These labels have been obtained from specialized vocabularies represented by means of domain-specific ontologies described using RDF and transformed using a LOM to RDF binding. They are included as LOM standard metadata under the classification subcategory. In order to test its viability, the proposed extension has been implemented as an additional functionality of a learning object editing tool developed as part of the MD2 project
