Defining Object-Process Methodology in Web Ontology Language for Semantic Mediation

Model-Based Systems Engineering (MBSE) is gradually becoming an acceptable good practice, especially for large-scale complex systems. The variety of modeling languages allows detailed representation of domain-specific knowledge of different components and aspects of a system. Semantic Web concepts provide opportunities for easier and more efficient collaboration between design and verification teams using different modeling tools. IBM Semantic Mediation Container (SMC) is a tool interoperability platform, allowing mediation and synchronization among models in different languages based on their ontologies. We propose integrating into SMC the ability to translate Object-Process Methodology (OPM), the emerging ISO 19450 Standard, which provides a holistic view of the system´s function, structure, and behavior. In this paper we describe the first integration stage - defining the OPM ontology in a way that conforms to Semantic Web specifications. We discuss different approaches of element representation and validate the ontology by round-trip transformation of OPM models from their visual representation to Resource Description Framework (RDF) and back.
