Learning opportunities play an important role in the vision of curriculum favored by the Bologna Process. This paper proposes an ontology intended for representing learning opportunities. The ontology is designed in accordance with European standardized models addressing metadata sufficient for representing learning opportunities. Since the models are proposed as Dublin Core application profiles, the ontology has been implemented following a set of guidelines for expressing Dublin Core application profiles using OWL. Proposed ontology facilitates the introduction of Semantic Web technologies in the field of curriculum management, and will bi a start-point for the implementation of a Semantic Web application aimed at curriculum management.
