Abstract Competency is a central concept for human resource management, training and education. We define competency as the capacity of person to display generic skill with certain level performance when applied one or more knowledge entities. Competencies, referentials grouping competencies, are essential elements user models, e-Portfolios, adaptive learning, personalization in Technology-based learning. But be processed both by humans software tools, competencies should represented formal, non-ambiguous model called an ontology. Moreover, this use shared vocabulary describe skills Defining linking vocabularies purpose ontologies semantic web. The goal our research develop ontology web used referential description profiles. analysed five previous models developed COMP2, new that integrates important richness vocabulary. COMP2 provides processing capabilities computers. Its graphic highly readable design, evaluation communication purposes. It also translates, together its data sets, standard Web code machine processing. composed stages interlinked other within linked open data. will present example competency-based learning environments.
