On ISOA: Intentional services oriented architecture

Despite the growing acceptance of SOA, service-oriented computing remains a computing mechanism to speed-up the design of software applications by assembling ready-made services. We argue that it is difficult for business people to fully benefit of the SOA if it remains at the software level. The paper proposes a move towards a description of services in business terms, i.e. intentions and strategies to achieve them and to organize their publication, search and composition on the basis of these descriptions. In this way, it leverages on the SOA to an intentional level, the ISOA. We present ISM, the model to describe intentional services, and to populate the service registry. We highlight its intention driven perspective for service description, retrieval and composition. Thereafter, we propose a methodology to determine intentional services that meet business goals. Finally, we introduce agent architecture to support model driven execution of intentional services.
