Object-Oriented Meta Modelling

TL;DR: A meta-modelling technique based on object-oriented concept for the method base system, which provides method fragments with high modularity and reusability and how to customize method fragments and to integrate them to a new method is discussed.

Abstract: For efficient system specification development, it is very important that the developers can compose the development methods suitable for their problem domain and environment before starting system development. Method Engineering, especially meta-modelling technique, provides us with the powerful devices to compose the methods effectively. In this framework, we develop new methods and their supporting tools easily from the data base of the existing methods and/or method fragments (meaningful constituents of methods), called method base. This paper discusses a meta-modelling technique based on object-oriented concept for the method base system. Information hiding and inheritance mechanism in object-oriented concept provide method fragments with high modularity and reusability. Method fragments are modelled and described in object-oriented formal description language Object Z. We also discuss how to customize method fragments and to integrate them to a new method.
