Unifying Architectural and Behavioural Specifications of Distributed Components

We present a novel specification language called JDC to be used at design phase of distributed components. The extensive seek for asynchrony in distributed components demands new techniques for its specification that have not been addressed before. We propose to focus the specification on its data-flow; this allows to reason about inter-component synchronisations produced by a data-driven synchronisation model. The language is endowed with enough formality so it allows a constructive approach; it allows the generation of behaviour models which can be model-checked, and the generation of code skeletons with the control flow of components. Globally, this approach aims at generating components with strong guarantees w.r.t. their behaviour.
