[PVS] Call for papers: FLACOS07 CALL FOR PAPERSFirst Workshop on Formal Languages and Analysis of Contract-Oriented Software (FLACOS'07)Oslo, Norway, 10-12 October, 2007 http://www.ifi.uio.no/flacos07The fast evolution of the Internet has popularized service-oriented architectures with their promise of dynamic IT-supported inter-business collaborations. Realizing this promise involves integrating services which are geographically distant and are offered by a variety of organizations which do not fully trust each other. Indeed, collaboration presumes a minimum level of mutual trust. Wherever trust is perceived as insufficient, business people turn to contracts as a mechanism to reduce risks. The ability to negotiate contracts (e.g. for quality of service, security, and distribution of information) and to provide services based on them is therefore one of the most pressing needs to make collaborations a reality. High-level models of contracts are slowly making their way into service-oriented architectures, but application developers are still left to their own devices when it comes to writing code that will comply with a contract concluded just before service provision. At the programming language level, contracts appear as separate concerns that crosscut through application logic. The aim of this workshop is to bring together researchersand practitioners working on language-based solutions to the above problem through the formalization of contracts,the design of appropriate abstraction mechanisms that would guide the developer in the production ofcontract-aware applications, and formal analysis of such contract languages/software.IMPORTANT DATES Paper Submission Deadline: September 3, 2007Notification of Acceptance: September 15, 2007Registration for authors closes: September 25, 2007WORKSHOP: October 9-10, 2007FLACOS'07 is partially supported by the Nordunet3 project "Contract-OrientedSoftware Development for Internet Services".
