**** CALL FOR PAPERS **** 3rd International Workshop on Web Service Composition and Adaptation (WSCA-2009) Website: http://lsdis.cs.uga.edu/WSCA2009 July 6th, 2009, Los Angeles, California, USA Affiliated with the IEEE International Conference on Web Services, 2009 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 RESTful services widely used in Web applications. Correspondingly, the construction and deployment of mashups 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, this workshop, to be held in conjunction with 2009 IEEE International Conference on Web Services, 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. *Specific topics of interest include* - Dynamic service discovery and selection - Semantic annotation and mediation of services - Ontology-based approaches to service composition and mashups - Domain specific languages for mashups - Formal methods in service composition - Verification of service compositions - Reuse in service composition: service compatibility and substitution - Adaptation and Evolution of services, including modeling of events that impact service compositions and mashups, and techniques to respond to these events - Case studies, and applications (e.g., in e-science, e-Business, e-Government, mobile computing, social computing, sensor networks) *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 8 pages and following the formatting of the IEEE Computer Science Proceedings template: http://conferences.computer.org/icws/2009/IEEEProceedingsTemplate.doc Papers can be submitted electronically via the Confhub ( http://confhub.com/conf.php?id=114) submission management system. At least one author is required to attend the workshop and present the paper. *Workshop proceedings* Accepted WSCA papers will be published IEEE Proceedings of Congress on Services (SERVICES 2009-Part I), which will include some other tracks in addition to workshop papers. *Important Dates* Paper submission: March 10th, 2009 (EXTENDED DEADLINE!!!)
