The ability to negotiate contracts for a wide range of aspects and to provide services conforming to them is a most pressing need in service-oriented architectures. High-level models of contracts are 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 provisioning. At the programming language level, contracts appear as separate concerns that cut across application logic, while analysis requires that contracts are abstracted from applications to become amenable to formal reasoning using formal language techniques. The aim of this workshop is to bring together researchers and practitioners working on language-based solutions to the above issues through formalization of contracts, design of appropriate abstraction mechanisms, and formal analysis of contract languages and software.

The workshop will consist mainly of a number of presentations by invited speakers. A small number of additional sessions will be reserved for other researchers in the field who are encouraged to submit a short abstract of their work as an expression of interest in participating in the workshop by 23 September 2008. The number of participants in the workshop is strictly limited.

FLACOS'08 is partially supported by the Nordunet3 project "Contract-Oriented Software Development for Internet Services" (COSoDIS).

Typical topics of the workshop include (but are not limited to):

• Formal languages for contracts
• Contract-oriented software development
• Formal analysis of contracts, including static analysis, run-time verification, and model checking techniques
• Contract synthesis
• Contract transformation and contract refinement
• Contract negotiation, discovery and monitoring
