Viewpoint modeling is an effective technique for specifying complex software systems in terms of a set of independent viewpoints and correspondences between them. Each viewpoint focuses on a particular aspect of the system, abstracting away from the rest of the concerns. Correspondences specify the relationships between the elements in different views, together with the constraints that guarantee the consistency among these elements. However, most Enterprise Architectural Frameworks, which follow a multi-viewpoint approach, either do not consider the explicit specification of correspondences, or do it in a very simplistic way. In this paper we examine the representation of correspondences in the context of the RM-ODP, identify some of its related issues, and propose some improvements to the way in which correspondences are modeled. In particular, we claim that multi-viewpoint modeling approaches need to specify not only the correspondences between the system views, but also some well-formed rules on such set of correspondence specifications.
