Une approche formelle de l'interopérabilité pour une famille de langages dédiés. (A formal approach for interoperability in a family of DSLs)

In this thesis, we introduce a rigorous formally founded method to address the interoperability of a family of domain specific languages (DSLs). Our approach targets DSLs from the same business domain and consists in constructing a unifying language. The unification is obtained by using a categorical approach. For this, we use the category of algebraic specifications of each language in the family. On this category, we apply the colimit on algebraic specifications of each DSL to generate their unifying. This approach allows us to obtain a set of translators from each family member to the unifying language. Moreover, properties established in the context of a language of the family are transferred to the unifier. The approach experimented in the context of the Specware software for categorical computations and of the Isabelle proof assistant.
