Moreover, communication between (legacy) business application systems federated to "produce" a given product has to be ensured on a semantic level. To support this scenario, we introduce a generic federation layer that uses an object-oriented approach as well as the WebComposition Markup Language to facilitate the reuse of code and design. In addition, we show how a semantic inter-application communication can be provided by means of a second basic federation layer. 1 Introduction In the ensuing decade the use of the World Wide Web (WWW, Web) has moved far beyond of its originally anticipated scope. As a matter of fact we notify its gradual change from a distributed system for knowledge-interchange towards a new applica...
