Spekl: A Layered System for Specification Authoring, Sharing, and Usage

Compositional reuse of software libraries is important for productivity. To promote reliability and correctness, the field also needs a way to compose specifications for reuse. How-ever, specifications cannot be adapted by the use of wrappers in the same ways as code can, which leads to specifications being copied and modified. This copying and modification of specifications leads to poor maintainability and technical debt. We propose a system, Spekl, that solves these problems and makes compositional reuse of specifications possible in a way independent of the choice of specification languages and tools.
