Call for Papers Recent advances in networks, information and computation grids, and Web languages and protocols have enabled development of, and led to the proliferation of, distributed and autonomously developed Web services. These include WSDL/SOAP based services well suited for enterprise applications as well as lighter-weight WebAPIs and REST-ful services widely used in Web applications. Correspondingly, the construction and deployment of mashup and composite services that combine and reuse independently developed component services is an important capability in the emerging Web-based computing infrastructure. Given that business and application needs continually change, and component services may also independently change, a number of challenges in provide dynamic, flexible and adaptable approaches to such integration and composition of services remains an important challenge. Against this background, the proposed workshop invites manuscripts addressing various aspects related to (a) discovery or selection of component services that will be integrated, (b) use of semantics to ease data mediation and integration of component services, (c) developing approaches to handling service failures, changes in service functionalities, and changes to quality of service parameters, and (d) understanding external events, which are the sources of volatility in service compositions. Insightful examples of and approaches to service composition and adaptation in a variety of applications such as scientific and engineering workflows, mobile computing, sensor networks, consumer and social networking, are welcomed as well. Additionally, we invite discussions of toolkits that support composition and adaptation objectives. TimelinessAs noted above, there is a growing awareness that solutions to the problem of Web service composition are crucial for reaping the benefits of autonomously developed services. Recent enterprise-focused research has focused on developing solution methodologies by using well-studied techniques in domain of software composition, planning, formal verification etc. Independently, Web or consumer focused application developers have made rapid progress in development and deployment of mashups that deal with distinctly different technologies and approaches for composing constituent services. The two communities have had limited communications. As such it is necessary to bring together researchers and practitioners from different domains with varying research background and build a knowledge base cross-cutting the fields of distributed computing and middleware, Web technologies, software engineering, artificial intelligence and formal methods to effectively address some of the problems aforementioned. The objective of the proposed workshop is to bring together researchers and practitioners to discuss the current state of the art and open research problems in Web service composition and adaptation. In addition to applications areas addressed in past workshops (e.g., e-Science, e-Business, e-Government ), this workshop will provide a forum for some of the newer applications of composition and adaptation capabilities, specifically in scientific workflows, social computing, mobile computing and sensor networks area. Specific topics of interest include (but not limited to):
Submission Authors are asked to submit original, unpublished research papers that are not being considered for publication in any other forum. At least one author is required to attend the workshop and present the paper. Papers must be limited to 8 pages and following the formatting of the IEEE Computer Science Proceedings template.Please use the 2009 WSCA Paper Submission and Review System to submit your paper to WSCA 2009.
