Document Adaptation

The increasing diversity of information, devices and networks makes the original scheme of the Web inefficient. The usual model of a single Web page designed for a large color screen accessed through a high speed network does not work any more. Some information providers face this problem by developing their contents into different versions, each one suited to a specific class of devices. Another approach is to create information in a single, universal format and to adapt it automatically to the environment where it is delivered.

The WAM project works along the second approach. It aims at developing models, methods, architectures, protocols, formats, languages that allow content to be adapted ''on the fly'' to the context in which it is actually used. In this approach, no restriction is put on the type of information that has to be adapted; multimedia information is considered with the broad diversity of media that are now commonplace on the Web.

Content adaptation is not something that comes into play at the last moment, when information is delivered to the client. To enable efficient adaptation, the original information must present some features that make adaptation easier or even possible at all. This means that the production methods should also be involved in the whole process of content adaptation. The WAM project is especially interested in authoring tools for the Web, with the perspective of creating multimedia documents that ease adaptation and improve device independence. Several editors are currently under development. LimSee3 is dedicated to the production of multimedia documents where time and synchronization play a key role. Amaya addresses multi-namespace XML documents containing text, mathematics, animated graphics and using style sheets. Finally new work has recently started to develop tools for manipulating spatialized sound in multimedia documents.
