Multimedia Models and Formats

Modeling and authoring web content including rich media and interactions is still an open problem. We have drawn a reference state of the art of this area in [17] . We have also contributed to the cultural heritage domain through the experimentation of a multimedia production chain for digitized theatre performances based on semantic annotations [12] .

In the context of the Claire project (see section  8.1.1 ), the results we obtained in 2013 in this area are:

• providing a data model which is format agnostic to cope with existing and future rendering systems. More specifically, we specified a chaptering component that includes the structuration and navigation features for continuous media such as video.

• prototyping a web environment for authoring such rich media (see section  5.2 . This authoring services are built as a contribution of the Mozilla Popcorn Maker project (Popcorn Maker ).

• experimenting this environment for the production of the multimedia part of the first MOOC developed by OpenClassrooms, our main partner in this project.
