Abstract. This paper provides a short description of an ontology of the capability maturity model, CMMI-SW. The ontology is coded in a formal language, OWL. Some possible uses of the ontology are introduced. The ontology is presented in a number of increments – from more general concepts to more specific. Justification for the selection of concepts and relations is given. To assess the validity of the ontology, a number of test cases were used. An OWL reasoner was then used to derive the results. While the test results were all positive, the ontology has a high value only if the community accepts it. The main goal of this paper is to announce the existence of such an ontology and to invite the community to contribute to its further refinement. 1

Abstract. Recent relevant efforts to shape the knowledge body of the discipline of Software Engineering have resulted in the crafting of different conceptualizations and ontologies both for specific or general purposes. But the underlying semantics of such knowledge representations are not defined formally, which would eventually require an effort of “harmonization ” or mapping of knowledge structures, and results in non-explicit computational semantics. This can be avoided or alleviated by the reuse of existing open upper ontologies. This paper sketches how some of the fundamental Software Engineering terms can be mapped to the large OpenCyc knowledge base. The tentative mapping described provides a sound basis for analysis and discussion between different alternatives to the creation of Software Engineering conceptualizations. 1
