The W3C Web Services Architecture defines ``Web service as a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine processible format (specifically WSDL) and other systems can interact with it in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards''. Correspondingly, the construction and deployment of composite services by combining and reusing independently developed component services is an important capability in the emerging Web-based computing infrastructure. Processes offer key IT capabilities in businesses as well as in scientific research, and key enabler of broad variety of applications including e-Enterprise, e-Business, e-Government, and e-Science. Since many processes need to change to adjust with respect to changing computing and business environments, adaptability of processes is also a key requirement. The workshop will be held in conjunction with IEEE International Conference on Web Services. ICWS is a ``prime international forum for both researchers and industry practitioners to exchange the latest fundamental advances in the state of the art and practice of Web services, identify emerging research topics, and define the future of Web services.'' The workshop will complement this theme of the conference and aims to conduct a focused discussion on one of the main topics of interest in Web service research: service composition. The discussions will not only bring out the current state of advances in Web service composition but also provide valuable insights for future research avenues and for work-in progress in the domain of Web service composition. Specific topics of interest include: - Model-based service composition - Static and dynamic service composition - Reuse in service composition: compatibility and substitutability - Adaptation and Evolution of services and processes - Formal methods in service composition - Verification of service composition - Fault tolerant service composition - Optimization in service composition and service/process adaptation - Ontology-based approaches to service composition - Secure service composition - Elicitation and modeling of functional and non-functional requirements in service composition - Comparing and ranking of alternative solutions in service composition - Software infrastructure for service composition - Case studies, and applications (e.g., in e-science and scientific workflows) Submission guidelines: Authors are asked to submit original, unpublished research papers that are not being considered for publication in any other forum. Papers must be limited to double-column 6 pages and follow the formatting of the IEEE CS Proceedings template ( ftp://ftp.computer.org/press/outgoing/proceedings/IEEE_CS_Latex.zip). Papers can be submitted electronically via EasyChair submission management system (link to be made available soon). At least one author is required to attend the workshop and present the paper. Important Dates: Paper submission: March 16, 2007 (11:59pm Central Standard Time) Notification: April 23, 2007 Camera-Ready due: May 1, 2007 Workshop date: TBA Organizing Committee: ` Samik Basu, Iowa State University Vasant Honavar, Iowa State University Marco Pistore, University of Trento Amit Sheth, Wright State University Program Committee: TBA -- Jyotishman Pathak WWW: http://www.cs.iastate.edu/~jpathak
