A formal model for module interconnection languages

A model is proposed that formalizes the design of hierarchical module structures. The model is specified by a collection of Z schema type definitions that is invariant across all applications. A particular application is described by specifying the values of generic parameters and adding application-specific declarations and constraints to the schema definitions. As applications, the definitions in the model are used to describe the Conic configuration language and the STILE graphical design and development environment.<
