<p>A method of maintaining a database comprising a fingerprint of and an associated set of metadata for each of a number of multimedia objects. Respective portions (201, 202, 203, 204, 205) of the database are distributed over respective file sharing clients (101-105) connected to a file sharing network (100) arranged for sharing said numberof multimedia objects. File sharing clients (101-105) can maintain their own respective portions (201-205) of the database, or transmit fingerprints and metadata to another file sharing client. In the latter case, the other file sharingclient is preferably a supernode in the file sharing network (100).</p> |
