Madeus: an authoring environment for interactive multimedia documents

We present Madeus, an authoring environment for interactive multimedia documents. Madeus's aim can be summed up in the following statement: high temporal expressivity must not be reached to the detriment of a user-friendly interface editing approach. We provide the author with a declarative and hierarchical specification language based on an extension of Allen's (1983) algebra. Static temporal checking and dynamic scheduling are based on an extension of temporal constraint networks.
