A Web Engineering Approach to Model the Architecture of Inter-Organizational Applications
Johannes Meinecke, Martin Gaedke, Martin Nußbaumer · 2005
Abstract. During recent years, the World Wide Web (WWW, Web) has in-creasingly been used as a platform for applications that link together processes both between and across organizations. Acting as distributed components, Web Services provide a standardized way of externalizing functionality on a global scale and as such enable accesses that transcend organizational boundaries to form federated applications. The design and evolution of these federated appli-cations is now imposing new obligations for the disciplined engineering of composed Web solutions. To meet these obligations, we extend the WebCom-position idea, which is an approach to apply component-based software devel-opment concepts on Web applications. This extension facilitates modeling the complex landscape of the components and services building the federated ap-plications. In this context, we introduce the WebComposition Architecture Model that serves as a map to keep track of the interrelations between the fed-erated partners in terms of the involved Web-technology. Among the modeled artifacts are Web services, Web Applications and organizational zones of con-trol that are all subject to evolution in the sense of the WebComposition ap-proach. 1
