Abstract

Domain ontologies are valuable knowledge assets with many potential applications, e.g. in software engineering. Their content is often a subject of bi-directional transformations. Unfortunately, a centralized transformation service which can be easily extended with new mappers is not available for ontology users. In consequence, they have to deal with many different translation programs, which have to be installed and learned separately. The paper presents a framework for universal ontology processing, dedicated to ontologies expressed in OWL2. The framework usefulness was verified by a proof-of-concept implementation, for which an existing OWL2 to Groovy translator was adapted. During the integration process, the translator functionality was enhanced with ontology individuals mapping. The exemplary implementation confirmed that the framework with plug-in architecture is flexible and easy for customization. The ontology stakeholders should benefit from the reduced cognitive load and more satisfying transformation process.

Abstract

The domain knowledge represented by ontology should be widely used in the design process of information system. The aim of the paper is to outline a systematic approach of developing a CIM model (domain model, precisely) on the basis of a selected domain ontology. There are presented some hints how ontology concepts can be expressed in domain model. Elaborated example realizes some difficulties in proposed approach, e.g. the domain knowledge is spread over many ontologies, some facts are defined at very general level (their interpretation is more difficult), ontology may contain many irrelevant elements. Nevertheless, we are believed that applying ontology in conscious way can help to achieve higher compliance of the domain model with the application domain.
