Multimedia data has become readily available from a variety of resources, such as the Web, to users (ranging from naive to sophisticated) who need to select and to present the data in a way that is meaningful to their particular applications. DelaunayMM is our framework for querying and presenting multimedia data stored in distributed data repositories, including the Web. It is unique in combining user-de ned layouts with ad hoc querying capabilities, thereby enabling users to tailor, in a simple way, the layout of virtual documents composed of retrieved multimedia objects. In this paper, we focus on the object-oriented data models, on the declarative query languages, and on how the results of the queries to disparate resources are integrated to form coherent user-de ned documents.
