---------------------------------------------------------------------- We apologize if you receive multiple copies of this announcement. ---------------------------------------------------------------------- ====================================================================== Call for Participation 2nd International Workshop on Web Services and Formal Methods (WS-FM 2005) 1-3 September 2005, Versailles, France http://cs.unibo.it/WS-FM05 Co-located with EPEW'05 2nd European Performance Evaluation Workshop * Early registration deadline: July 28th * ====================================================================== SCOPE Web Services technology aims at providing standard mechanisms for describing the interface and the services available on the web, as well as protocols for locating such services and invoking them (e.g. WSDL, UDDI, SOAP). Innovations are moving towards two main directions: The first one tends to the definition of new standards that support the specification of complex services out of simpler ones (the so called Web Service orchestration and choreography). Several proposals have been already set up: BPML, XLANG and BizTalk, WSFL, WS-BPEL, WS-CDL, etc... The second approach consists of the design of new (meta-)Web Services to be exploited at run-time by other Web Services: e.g. managing the cooperation of Web Services or acting as dynamic registry services. Formal methods, which privide formal machinery for representing and analysing the behavior of communicating concurrent/distributed systems, may potentially play a fundamental role in the development of such innovations. First of all they may help in understanding the basic mechanisms (in terms of semantics) which characterize different orchestration and choreography languages and to focus on the essence of new features that are needed. Secondly they may provide a formal basis for reasoning about Web Service semantics (behaviour and equivalence): e.g. for realizing registry services where retrieval is based on the meaning of a service and not just a Web Service name. Thirdly also studies on formal coordination paradigms can be exploited for developing mechanisms for complex run-time Web Service coordination. Finally, given the importance of critical application areas for Web Services like E-commerce, the development of the Web Service technology can certainly take advantage from formal analisys of security properties and performance in concurrency theory. The aim of the workshop is to bring together researchers working on Web Services and Formal Methods in order to activate a fruitful collaboration in this direction of research. This, potentially, could also have a great impact on the current standardization phase of Web Service technologies. LIST OF TOPICS The topics of interest include, but are not limited to: - Protocols and standards for WS (SOAP, WSDL, UDDI, etc... ) - Languages and descripion methodologies for Coreography/Orchestration/Workflow (BPML, XLANG and BizTalk, WSFL, WS-BPEL, WS-CDL, YAWL, etc... ) - Coordination techniques for WS (transactions, agreement, coordination services, etc...) - Semantics-based dynamic WS discovery services (based on Semantic Web/Ontology techniques or other semantic theories) - Security, Performance Evaluation and Quality of Service of WS - Semi-structured data and XML related technologies - Comparisons with different related technologies/approaches INVITED TALKS Peter Harrison, Imperial College London "Performance Engineering and Stochastic Modelling" Gianfranco Ciardo, University of California "Implicit representations and algorithms for the logic and stochastic analysis of discrete--state systems" Cosimo Lavene, University of Bologna "PiDuce: A Process Calculus with Native XML Datatypes" Wil van der Aalst, Eindhoven University of Technology "Life After BPEL ?"
