Some multimedia archives contain data which have vague locations in time and space. By this we mean that, although there is some idea of when and where the entity is located, the precise information is unknown. In this paper, we present a novel approach to displaying and querying such uncertain data. We use the concepts of dynamic queries, add to this a 2D query tool for performing spatial queries and enable Boolean combinations of queries. We have implemented these ideas in a pilot system for querying African artwork. In this way, we show how it is possible for novice users to easily query large multimedia archives with complex uncertain attributes.
