Intégration d'imitations de patrons pour la spécification de cadriciels

New approaches to the development of information systems, based on components reuse, are now preferred to traditional ones. Patterns and frameworks are among the most frequently “re-used” components in such approaches. In particular, patterns are frequently used for the development and the adaptation of a framework. Nevertheless, the development and the adaptation of a framework are two processes still totally separated. Moreover, the patterns used for the development of a framework are finally lost. This article presents first results, which preserve two properties that we think fundamentals. First, the trace ability of the framework development process must be preserved in order to facilitate its understanding and its further maintenance. Second, the design of a framework must condition its adaptation; in other words, the know-how used during the design of a framework must be used and preserved by the know-how used during its adaptation. We assert that it is then necessary to reason on frameworks conceptual schemes that we see as integrations of patterns imitations. The results presented in this article are issued from a particular approach consisting in the reverse engineering of a specific framework.
