| The semantic web promises to bring automation to the areas of web service discovery, composition, and invocation. In order to realize these benefits, rich semantic descriptions of web services must be created by the software developer. Therefore, a steep learning curve and lack of tool support for developing such descriptions thus far have created significant adoption barriers for semantic web service technologies. This research makes four primary contributions: (1) the development of an approach that enables the specification of atomic and composite services; (2) the creation of model transformations that convert UML class and activity diagrams into OWL-S and other associated representations; (3) the development of software tools to facilitate the conversion, grounding, and execution activities; and, (4) a demonstration of semantic web service technology and an evaluation of the approach. These contributions together form a model-driven framework for semantic web service development. |
