Delaunay/sup MM/: a visual framework for multimedia presentation

We introduce a visualization framework called Delaunay/sup MM/ for querying and presenting multimedia information in distributed databases. Users can tailor the layout of virtual documents containing multimedia information at the same time as they specify their contents in an intuitive yet formal way, using a Web-available interface. The data model that we propose is object-oriented, and the query and presentation languages are declarative and incorporate layout constraints. Our framework encompasses the retrieval of heterogeneous distributed information whose data model does not need to conform to the one used by Delaunay/sup MM/.
