An Ontology-Driven Architecture for Semantic Web Service Composition

Nowadays Model-Driven Architecture (MDA) techniques applied to Web service development are considered an emerging trend in web engineering. MDA emphasizes abstract modeling, considering models at three different levels of abstraction, namely Computer-Independent Model (CIM), Platform-Independent Model (PIM) and Platform-Specific Model (PSM). Typically, MDA process follows a top-bottom approach in which initial PIM models are transformed into PSM models until reaching the required implementation. However, in our opinion, MDA process lacks the ability to reuse existing PIM, and especially CIM models to be integrated in new web applications. In this paper, we present an ongoing ontology-driven architecture that enables using Semantic Web mechanisms in a MDA-based framework to facilitate the reuse of both semantic web service composition and knowledge.
