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.
