Well-formed Rules for Viewpoint Correspondences Specification

Abstract

Service Enterprise Architecture (SEA) is nowadays gaining a wider audience in companies using large-scale IT systems. It combines service orientation and viewpoint modeling. Hence, service orientation is attractive due to its ability to virtualize component architecture and to enable easier composition and contractualization. However, services may be defined at multiple levels (business, application, technology) and viewpoint modeling permits to adopt a systematic approach. This paper compares several frameworks (Zachman, RM-ODP) and methodologies (TOGAF/ADM, Praxeme, ThinkService). A special focus is made on their ability to handle viewpoint correspondences and evolution management.
