Service oriented software engineering for modeling agents and services in grid systems

Abstract

This paper studies how some technologies based on the Model Driven Architecture can be exploited to the design of service 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 service 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.
