With the introduction of the Model Driven Architecture by the OMG, modeling technology seems to take the step on the middleware technology for distributed applications development. The MDA recommends to separate the business from their technical aspects in the development of applications. Modeling techniques offer tools providing abstraction that enables the isolation of business concerns from their technical achievement. EDOC Profile is an example of such tools as it provides a modeling framework. It makes use of the RM-ODP architectural framework that provides conceptual tools. These tools, so useful are, remain insufficient in the sense that they do not provide any process to guide the software designers in the modeling step, i.e., they are not methodological tools.

We present in this paper a methodology based on the RM-ODP that falls under the MDA initiative. We describe its principles by illustrating them with an example. Then we provide the research directions enabling to get a fully compliant MDA methodology.
