This paper introduces a modelling framework to perform automatic analyses on the specification of an information exchange policy. To avoid the increase of development costs and risks of uncontrolled dissemination of information, the specification errors need to be detected before the implementation phase. We propose a minimalist core language to unambiguously represent an exchange policy specification and a gateway to logic solvers to verify some properties, namely: completeness, consistency, applicability and minimality. The aim is to check whether the formalisation of an exchange policy is consistent with user expectations.

Model Driven Engineering practitioners already bene¦t from many well established veri¦cation tools, for Object Constraint Language (OCL), for instance. Recently, constraint satisfaction techniques have been brought to Model-Driven Engineering (MDE) and have shown promising results on model veri¦cation tasks. With all these tools, it becomes possible to provide users with formal support from early model design phases to model instantiation phases. In this paper, a selection of such tools and methods is presented, and an attempt is made to de¦ne a veri¦cation and validation process for model design and instance creation centered on UML (Uni¦ed Modeling Language) class diagrams and declarative constraints, and involving the selected tools. The suggested process is illustrated with a simple example.
