One strength of FESCA is the link established between the formal methods community and the software engineering community by exploring how formal approaches can be exploited for the analysis of large software architectures. We encourage submissions on formal techniques and their application that aid reasoning, analysis and certification of component and servicebased applications. In this context, the following topics are of particular concern: Architecture as a language: Building Domain-Specific Languages (DSLs) Modelling formalisms for the analysis of concurrent, embedded or and model-driven systems assembled of components and services; Modelling formalisms in prediction, analysis and measurement of software quality attributes such as reliability, performance, or security; Properties of component and service-based models Temporal properties (including liveness and safety) and their formal verification; Interface compliance (interface-to-interface and interface-to-implementation) and contractual use of components; Formal methods in Component-Based Software Development Techniques for prediction and formal verification of system properties, including static and dynamic analysis; Instrumentation and monitoring approaches, runtime management of applications; (Semi-) automatic inference of analytical models for existing software systems; Formal methods in Service-Based Software Development Techniques for behaviour modelling of services and their orchestration Static and runtime verification and monitoring techniques for ensuring service quality, such as reliability, security and safety Formal methods in Model-Driven Software Development Abstraction level in modelling formalisms; Safer MDA through integration with formal methods; Correctness of model transformations; Industrial case studies and experience reports. Submissions concentrating on specification techniques should involve an evaluation of the practical merit of their research and clearly state the analysis and reasoning techniques they enable. We also appreciate work of a formal nature with immediate value to for the industrial context. We encourage not only mature research results, submissions presenting innovative ideas and early results are also of interest.
