Adaptable process engineering survey: Adaptive services grid deliverable D6.I-3

The mission of the ASG project is to combine the two fields of Semantic Web Services and Grid Computing to offer new applications based on Grid Services with a well-defined range on quality of service. Although the basic concepts of Software-Oriented Architectures, Web Services, and Grid technologies have become very popular in the last few years and are recognized as enabler architectural styles for modern enterprise and scientific applications, much confusion remains concerning strategies and processes suitable for engineering Gridenabled Web Services. This document surveys the state of the art and practice in the field of processes aimed at engineering semantic-oriented Grid-enabled solutions. Processes for the engineering of Grid infrastructures are out of the scope of this document. The results of the survey let us conclude that some standard practices are currently available for Web Services engineering, although, in many cases, their integration turns out to be problematic; concerning the engineering of semanticoriented service-based solutions, it is, at the moment, very difficult to determine standard engineering practices mainly due to missing standardization of those infrastructures, which would potentially be capable of supporting this kind of solutions. Major contributions of this document to the goals of the ASG project include a systematic analysis of the fields related to the project, a structured overview of the technologies available in the fields as well as their mutual relationships, and a deep analysis of the processes currently available for engineering many of the solutions to be provided by the project. This document can provide valuable input to work packages C0, Project Management, due to the analysis of suitable engineering processes; C1, ASG Interface, due to the overview on available technologies; and C7, Usability and Demonstration, due to the analysis of suitable engineering processes. Furthermore, the document provides a basis for the further work of C6, ASG Development Methodology
