An Intentional Approach to Service Engineering

Abstract

International audienceDespite its growing acceptance, Service-Oriented Computing (SOC) remains a computing mechanism to speed up the design of software applications by assembling ready-made software services. We argue that it is difficult for business people to fully benefit of SOC if it remains at the software level. The paper proposes a move toward 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 SOC to an intentional level, ISOC. We present ISM, the model to describe intentional services, and populate the service registry with their descriptions. 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 and to publish them in the registry. Finally, the paper introduces a set of transformations to bridge the gap from the intentional level to the implementation one

A Systematic Literature Review on Service Description Methods

“…Business Process -Technology Mapping approaches help in a better alignment of business processes to services based applications. From the 24 service description methods found in the study [7], [16], [17], [27] were targeted at a better alignment of business -technology mappings.…”

“…In fact there are considerable number of emerging approaches ( [7], [16], [17], [27]) targeted at closing the gap between technical service description techniques and the common RE specifications.…”

“…[4], [9], [14], [18][19][20][21][22][23][24][25][26] Gap between business oriented and IT oriented Service Realizations. [7], [16], [17], [27] Lack of dynamic adaptability and situation awareness [9], [14], [23], [28] Producer only centric approaches [29], [31] Imprecise Requirements Specification…”

A user-centric vision of service-oriented Pervasive Information Systems

“…For instance, [17][35] propose a methodological guidance for defining new services based on the intentions these services are supposed to satisfy. These authors assume that such an intentional-driven approach should avoid the current mismatch of languages between low-level service expressions such as WSDL statements and business perceived services [35]. Similarly, [17][23] also consider an intentional-driven process.…”

“…Works such as [23][30] [35] satisfy requirement R4 (Goal oriented), but they fail considering requirement R3 (Contextawareness), since they do not consider execution context. On the other hand, [36] consider both user's intentions and execution context on GSF framework (Goal-based Service Framework).…”
