4th Workshop on Emerging Web Services Technology (WEWST 2009)

The 2009 Workshop on Emerging Web Service Technology (WEWST), collocated with the European Conference on Web Services (ECOWS), is the premier workshop for academic and industrial communities to discuss innovative ideas and research contributions advancing the state-of-the-art in Web service technologies. Although the advantages of Web services to allow businesses to interact with each other while maintaining a loose coupling are well known, there are still many challenges to be solved in this important field of research. The wide variety of tools, techniques, and technological solutions presented in WEWST share one common feature: they suggest new directions for Web service research by introducing new and sometime controversial ideas into the field. The workshop allows participants to gain new insights and to start collaborations by discussing how their own work can be used in related but different areas.
