—This poster describes the aim and the main research activities carried out within the project Multimodal and Multidimensional Content and Media of the ICT Department of the National Research Council in Italy. The project, which involves 10 research Institutes of CNR and about 141 man year effort, is aimed at making advances in all the various phases of the digital content life cycle: from the acquisition and creation to the presentation and interaction with the final user and/or software applications in the view of the effective creation of a society of knowledge where the content is active, easily accessible and rich of information. Considering the stronger digital convergence, the fundamental assumption of the project is that such a leveraging step from “passive” to “active” content can only be achieved if all the knowledge available at each processing step can be captured and exploited.
