We present a graph-based object model that has been used as a uniform framework for direct manipulation of multimedia information. After a brief introduction motivating the need for abstraction and structuring mechanisms in hypermedia systems, we introduce the data model and the visual retrieval environment which, combining filtering, browsing and navigation techniques, provides an integrated view of the retrieval problem.
