Multimedia documents are an effective way to present different kinds of information, since the integration of different media types gives more expressive power and opportunities to catch the user attention. A multimedia report is a multimedia presentation built on a set of data returned by one or more queries to multimedia repositories, integrated according to a schema with appropriate spatial layout and temporal synchronization, and coherently delivered to a user for browsing. We discuss the problem of defining schemas for such multimedia reports with a focus on the media coordination and synchronization constraints. Multimedia presentations can then be automatically generated according to the schema. We have defined an XML language to describe the spatial layout and the temporal constraints of the media objects, together with a visual authoring system helping the user to design the presentation template.
