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. While JavaScript is fine for handling timing, synchronization and user interaction in specific multimedia pages, we advocate a more generic, document-oriented alternative relying primarily on declarative standards: HTML5 and CSS3 complemented by SMIL Timesheets. This approach 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.
