This paper proposes a new technique for modeling document content for functional multimedia retrieval. Document contents and their interrelations are combined in a manner that accentuates the functionality of retrieval and contribute to a new level of document description. We describe a model of a so-called 'active document' that provides precise inheritance of other document models, whose properties can be embedded as characteristics in active document objects. As a concrete exploitation of the proposed model, we demonstrate with an experimental content-based multimedia document retrieval system using active document properties. The tests indicate a better response, recall and speed up of the query time.
