Abstract : In this paper, we explore different ways to publish multimedia documents on the web. We propose a solution that takes advantage of the new multimedia features of web standards, namely HTML5 and CSS3. To avoid the usual development of complex scripts for handling timing, synchronization and user interaction, we propose to complement HTML5 and CSS3 with SMIL Timesheets. This is made possible by a Timesheets scheduler that runs in the browser. Various applications based on this solution illustrate the paper, ranging from media annotations to web documentaries.
