This is an operational ontology as a supplementary material to accompany the paper "Towards Ontology-based Competence Modeling in Enterprise Architecture" by Rodrigo F. Calhau, Carlos L. B. Azevedo and João Paulo A. Almeida.
It extends the gUFO ontology (A Lightweight Implementation of the Unified Foundational Ontology) by specializing gUFO classes with competence-related classes (PersonalCompetence, CompetenceType, etc.) as discussed in the paper.
The namespace for the ontology is http://purl.org/nemo/competence. It can be directly imported in Protégé.
