Specifications recently proposed as standards in the domain of Technology Enhanced Learning (TEL), question the designers of TEL systems on how to put them into practice. Recent studies in Model Driven Engineering have highlighted the need for a framework which could formalize the use of these specifications as well as enhance the quality of the developments. This paper deals with the opportunity for the TEL community to adopt such a model to express and formalize the design organization and the engineering process of a TEL system. This kind of model could provide a set of concepts allowing the description of specifying, modeling and analyzing tasks one needs to perform for defining the negotiation and the communication between actors in such a community. In a first part, we stress the need for the instantiation of this framework so as to integrate recent results as well as taking into account the evolution of software reengineering. In a second part, we propose two instances of this framework; the first concerns the reverse engineering of a TEL system and the second its reengineering. (Contains 12 figures and 1 table.)
