| Résumé |
Sound databases are widely used for scientific, commercial and artistic purposes. Nevertheless there is yet no standard way to manage them. This is due to the complexity of describing and indexing audio content and to the variety of purposes a sound database might address. Recently there appeared Mpeg7, a standard for audio/visual content meta-data that could be a good starting point. Mpeg7 not only defines a set of description tools, but is more generally an open framework allowing to host specific extensions for specific needs in a common environment. This is crucial since there would be no way to freeze in a monolithic definition all the possible needs of a sound database. This paper tries to line out how the Mpeg7 framework can be used, how it can be extended and how all this can fit into an extensible database design, gathering three years of experience during the CUIDADO and SemanticHIFI projects at IRCAM. |
