One common usage of the WWW is t o provide informa-tion services, e.g. for regional event calenders, university lecture management, travel information, etc. Their design requires a clear picture of the system's usage and the supported technical environment. The core of the problem is to provide flexible access units based on extended views o n some underlying database. The extension consists in escort information, links, operational facilities and means for the generation of diflerent presentations. W e shall call such units media objects. In order t o allow also a flexible presentation for them, we adapt the metaphor of a container. I n this way it is possible t o present the same information in various ways depending on the user' profile and the possible technical restrictions of the display device.
