Mapping SDL Specification Fundamentals to Core SDL Ontology

Marina Bagić Babac, Marijan Kunštić


This paper gives a contribution in the efforts of Semantic web ontology development. We have developed the core ontology for Specification and Description Language (SDL),an object-oriented, formal language defined by the International Telecommunications Union Telecommunications Standardization Sector (ITU-T) as recommendation Z.100. The language is intended for the specification of complex, event-driven, real-time, and interactive applications involving many concurrent activitiesthat communicate using discrete signals. Using SDL formal model for system specification we bridge the gap between ideas in our minds and the actual implementation of the system. Being visually appealing SDL provides us with a simple tool for communication either between the softwaredevelopers or between non-experts without advanced engineering skills. In this paper we propose the ontology for the basic SDL system and process elements. We also propose a formal framework of SDL Markup Language as a medium for translating SDL model to SDL ontology.
