   ABSTRACT = {Electronic documents have been mainly considered through their logical structure
	(organization of documents in chapters, sections, etc.), their spatial structure (graphical
	layout) and their semantic structure (hypertext). With the advent of new computer systems
	handling multimedia data like audio and video, the temporal structure is more and more
	considered. The design of a document model integrating these various structures remains a
	difficult task, because, on one hand, the multimedia objects have different properties, and on
	the other hand, the extension of traditional documents models to the temporal dimension requires
	heavy changes. In this paper, we expound these problems and propose some solutions.
	These solutions are based on our experience in designing and implementing a structured
	multimedia authoring system called MADEUS.}
