An object-oriented schema for querying audio

To be fully usable, digital multimedia contents should be supported by a set of tools to query them, and more generally to manipulate them. This is one of the major goals of an audio database management system (DBMS). Existing work, e.g., radio or television archives, generally tackles the signal processing aspects, often leaving the DBMS question open. In this paper, we lay the foundations for integrating audio into a general purpose DBMS in the form of an object-oriented library. This library provides additional capabilities on top of (MPEG-7) audio descriptions used for mere selections.
