In the talk I will give a survey on the co-design approach to the development of Web Information Systems starting from characterististic properties of such systems. In order to cope with the sheer number of web pages that are needed in this systems, classification and conceptual abstraction become first necessities. This leads to the notion of media types, for which I will discuss problem of adaptivity and granularity. I will further illustrate how media types capture dynamic interfaces in an abstract way, while at the same time providing the means for efficient database-coupled implementation. In a second step I will address the modelling of Web Information Systems on higher levels of abstraction taking particularly care of usage as well as strategic aspects. This will lead to storyboarding. I will conclude the talk by pointing out various challenges that still exist with the method centred around problems of personalisation and reasoning.
