Formal Verification of Object-Oriented Software

Abstract

We propose a formal approach for the definition of domainspecific modelling languages (dsmls). The approach uses basic Model-Driven Engineering artifacts for defining a dsml's syntax (using metamodels) and its operational semantics (using model transformations). We give formal meanings to these artifacts by mapping them to the K semantic framework. Since the K definitions are executable, one obtains an execution engine for dsmls and gains acces to K's formal analysis tools. We illustrate the approach on xspem, a language for describing the execution of tasks constrained by time, precedence, and resources.
