Work on embedding reasoning about programs in a mechanised logic has mostly focused on meta-theoretic reasoning about programming logics or notations. This paper describes an attempt to formalise a theory of actions systems in HOL, in such a way that a tool for developing and reasoning about distributed and reactive systems can be built on top of the theory. By reducing action system refinement proofs to proofs of data refinement between sequential statements, we are able to reuse existing theories and tools for sequential programs.
