Transformation from OntoUML models to the OpenAPI Specification

This paper addresses a transformation for integrating OntoUML models, an ontology-driven conceptual modelling language, with the OpenAPI Specifi- cation for RESTful APIs. Despite OntoUML’s expressiveness in capturing complex relationships within domains, a significant gap hinders effective collaboration between ontologists and developers. A systematic transforma- tion process, preserving semantic richness, and providing user-friendly tools helps to bridge this gap. The result combines a literature review, practical im- plementation, and qualitative insights to achieve a transformation which can help with understanding and collaboration within software development.
