Emerging Web Services Technology

As Web services technology is becoming widely established in enterprise computing applications, Web services research is a very important and still very productive research domain. This book gives a timely report on the leading edge of this area by covering a wide spectrum of active research topics like Model Driven Engineering for SOA, Mobility and Services, Dynamic Web Service Discovery and Composition, Service Management, and Semantic Web. In particular, the book collects selected and revised papers originally presented at the first Workshop on Emerging Web Services Technology (WEWST) held in conjunction with the 4th European Conference on Web Services (ECOWS'06) last December 2006 in Zurich, Switzerland.

Zusammenfassung
The Workshop on Emerging Web Services Technology (WEWST06) took place in conjunction with the 4th European Conference on Web Services (ECOWS'06) on 4th December 2006, in Zurich, Switzerland. Acting as the natural extension to the main ECOWS conference, the main goal of the WEWST workshop is serving as a forum for providing early exposure andmuchneededfeedbacktogrowandestablishoriginalandemergingideaswithin the Web Services community. The wide variety of tools, novel techniques and emergingtechnologicalsolutionspresentedinWEWSTshareone commonfeature: they advance the current Web services research in new directions by introducing new and sometimes controversial ideas into the ?eld. WEWST focuses on research contributions advancing the state of the art in Web services technologies in the following areas: Model Driven Engineering for SOA, Mobility and Services, Streaming Services and Event Driven Architectures, Dynamic Web Service Discovery and Composition, Lightweight Orchestration- gines, SLA Creation and Service Delivery, Semantic Web, Managing Change and Service Evolution, Business Driven Development, Service-Oriented Grid Comp- ing Middleware, Business Process Management for Web Services, Software and Service Engineering. WEWST covers the whole spectrum which makes it a very important part of ECOWS.
