Rewriting logic is a natural semantic framework for representing concurrency, parallelism, communication and interaction, as well as being an expressive (meta)logical framework for representing logics. It can then be used for specifying a wide range of systems and programming languages in various application fields. In recent years, several executable specification languages based on rewriting lo
