OOZS: an object-oriented structured formal specification language

OOZS, which stands for ‘Object-Oriented Z Structured’, is an extension of the formal specification language Z to accommodate object orientation. It extends Z with a number of features that provide support for object-oriented design and management of specifications of very large systems. In addition to the usual object-oriented structures such as encapsulation into classes and inheritance, OOZS has some distinctive features: the Include facility, Import&Export mechanism, Pre&Post predicate, and the improved Delta&Xi list. This paper gives a brief description of this language.
