Structuring Mechanisms for an Object-Oriented Formal Specification Language

In this work we propose an extension of the MooZ formal specification language with support for parameterized packages. This enhances MooZ’s capabilities for software reuse and maintenance in the large. We discuss several design issues for MooZ’s structuring mechanisms: the distinction between inheritance and subtyping, values and objects, vertical and horizontal composition, packages and classes. We also analyse the impact of our design decisions on software reuse.
