Cooperative Specification via Composition Control

High-level, declarative specification languages are typically highly modular: specifications are comprised of fragments that are themselves meaningful. As such, complex specifications are built from incrementally composed fragments. In a cooperative specification, different fragments are contributed by different agents, usually capturing requirements on different facets of the system. For example, legal regulators and system administrators cooperate to specify the behaviour of a data exchange system. In practice, cooperative specification is difficult, as different contributors' requirements are difficult to elicit, express, and compose.
