The description and manipulation of the information embedded in video data is the key challenge for future multimedia technologies. The multilevel messages conveyed by time-varying visual data can be suitably handled only when a structured conceptual schema is built, which takes into account the multiple links among different elements of visual speech. In the paper a new schema for film data is introduced and a hypermedia navigation system is proposed, which is based upon this conceptual model. Such a system integrates the technical and visual content of a film into a comprehensive framework and makes it possible to navigate and display the different classes of content in a unconstrained sequence. The navigation task does not require any knowledge of complex query languages, since a query is structured as a form of data filtering through the formal operator of "perspective".
