Abstract : A multimedia document combines text, image, sound and video technologies. Currently, multimedia documents may have to be executed on multiple devices such as mobile phones, PDAs, desktop computers, set-top boxes, etc. Hence, usage and platform diversity requires document adaptation according to execution contexts, sometimes unpredictable at design time.

We propose to abstract from format specific details by defining a structure which expresses a set of multimedia objects and the relations between them. These relations can be described qualitatively and may be temporal, spatial, hypermedia and spatio-temporal-hypermedia. This document abstraction captures document semantics because it is able to cover all the potential executions of the document. In this context, adapting amounts to find a set of executions as close as possible to potential ones which satisfy adaptation contraints imposed by the target device. For that purpose, the relations contained in the document abstraction are modified in order to satisfy these adaptation constraints. We show how to achieve this convincingly on all the document dimensions

In order to show the applicability of our framework, we implement a prototype which adapts the temporal, spatial and hypermedia dimensions of SMIL documents. We develop specific efficient techniques for the temporal and spatial representations. Moreover, we explored other approaches such as considering multimedia object deletion.
