Enhancing Web Services in the Framework of Service-Oriented Architectures

Web services are emerging technologies that can be considered as the result of the continuous improvement of Internet services due to the tremendous increase in demand that is being placed on them. In this paper, the different facets of Web services are identified and a flexible approach to engineering complex Web services is adopted in the form of a proposed framework for the development of Web services. After the examination of its main constituent parts, it is argued that its full potential and that of Web service engineering in general, is realized through the gradual formation of a rich service grid offering value-added supporting functionality and therefore the main desirable properties of such a service grid are highlighted. Finally, the paper outlines a validation approach for the proposed framework and assembles important pointers for future work and concluding remarks
