An Extended Rule of the SysML Requirement Diagram Transformation into OWL Ontologies

Abstract

The System Modeling Language (SysML) used the Requirement Diagram to model non-functional requirements, such as response time, size, or system functionality, which cannot be accommodated in the Unified Modeling Language (UML). SysML Requirement Diagram, in its implementation, integrates with several diagrams describing the requirements, which are referred to as additional elements. The absence of transformation rules for these additional elements to become OWL ontology causes difficulties in reading, understanding, and tracking the requirements. In this research, an extended rule of the Requirement Diagram transformation is proposed to solve the problems. First, some transformation rules are defined to make requirements easier to trace and realize the ontology generation s automatic transformation. Second, the time required during transformation processing to prepare and generate the OWL file shows the proposed model s performance. The ontology components produced from this research, such as class, subclass, object property, and data property, can be viewed in Protégé.
