Abstract
This paper studies how some technologies based on the Model Driven Architecture can be exploited to the design of oriented applications. A uniform interaction method to engineer software in Service Oriented Architectures (SOAs), like for instance in Grid and Web Services, it is still a challenging problem. Starting from a modelation of the service abstraction in the Model Driven Architecture (MDA), a new approach based on Service Oriented Software Engineering (SOSE) is presented in order to integrate service-related technologies inside a single modeling framework for SOAs. SOSE shows how the Grid and Web Service convergence realized by the WSRF (Web Service Resource Framework) makes it possible to apply object-oriented design practices to the abstraction. The presented approach is supported discussing the design and use of a development tool for SOSE, named MOdeling TOol for Grid and Agent Services (MOTO-GAS). This tool, based on the MDA, allows to model services and their interactions by means of a metamodel hierarchy. Finally we describe an application scenario for MOTO-GAS modeling a Grid system for the Civil Protection domain.
