- relation between WWW service composition and GRID service composition
Summary/Conclusions
The workshop tackled the research problems around methods, concepts, models, languages and technology that enables composition of services in the context of the WWW. Of particular interest were the methodologies that enable automatic or semiautomatic composition of services, semantic web service web services, and e-services. Requirements on service composition with semantic web services were identified to be widely missing and needed for a successful assessment of composition in the context of WWW. Web languages for describing services and their relevance to composition were identified as key elements for enabling composition. Formal models were confirmed as the basis for service specifications and composition. Service composition engines were identified very limited in terms of functionality and not mature enough.
Mediation in composed services was identified to play an important role in the future: data, protocol, and process mediation will be key elements of service compositions. The lack of standards currently makes very hard any type of mediation in the context of service composition.
The workshop brought together researchers and industry attendees that addressed many of these issues, and promoted and foster a greater understanding of how the composition of services in the context of WWW can assist business to business and enterprise application integration.
As a result of the successful workshop, a new edition of this workshop is planned for the next year.
