For most users, authoring multimedia documents remains a complex task. One solution to deal with this problem is to provide template-based authoring tools but with the drawback of limited functionality. In this paper we propose a document model dedicated to the creation of authoring tools using templates while keeping rich composition capabilities. It is based on a component oriented approach integrating homogeneously logical, time and spatial structures. Templates are defined as constraints on these structures.

In this paper, we propose an export architecture that provides a clear separation of multimedia authoring services from publication services. We illustrate this architecture with the LimSee3 authoring tool and several standard publication formats: Timesheets, SMIL, and XHTML.

In this paper, we describe an approach to audiovisual data modeling for multimedia integration and synchronization. The approach chosen consists in using description tools from Multimedia Description Schemes of standard MPEG-7 to describe audiovisual contents and in integrating these description models into a multimedia integration and synchronization model close to SMIL. The resulting model provides relevant specification tools for the fine integration of multimedia fragments into multimedia presentations. An authoring environment illustrates the authoring features that can be obtained thanks to these integrated models.

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.
