In addition, this volume features three papers from the ECOWS’08 business track. WEWST focuses on research contributions advancing the state of the art in Web Services technologies. The main goal of the WEWST workshop is to serve as a forum for providing early exposure and much needed feedback to grow and establish original and emerging ideas within the Web Services community. The widevarietyoftools,techniques,andtechnologicalsolutionspresentedinWEWST share one common feature – they advance the current Web Services research in new directions by introducing new, sometimes controversial ideas into the ?eld. As such, WEWST is the natural extension to the main ECOWS conference. For this edition of WEWST, we accepted 6 full papers and 3 short papers. We would like to thank the paper authors for their submissions and for their contribution to the timely preparation of these proceedings, as well as for their presentations and lively discussions during the workshop.
