An Event-B framework for the validation of Event-B refinement plugins

TL;DR

This paper introduces an Event-B framework that models the theoretical foundations of Event-B, enabling validation of plugins and extensions related to distribution, composition, and decomposition.

Contribution

It presents a novel framework that formalizes Event-B's semantics and supports validation of plugins and extensions within the Event-B development process.

Findings

Framework successfully models Event-B semantics.

Enables validation of distribution-related plugins.

Supports composition and decomposition extensions.

Abstract

We propose an Event-B framework for modeling the underlying theoretical foundations of Event-B. The aim of this framework is to reuse, for Event-B itself, the refinement development process. This framework introduces first, a functional kernel through an Event-B context, then, it defines Event-B projects, their static and dynamic semantics through Event-B machines. We intend to use this framework for the validation of Event-B plugins related to distribution and for Event-B extensions related to composition and decomposition.
