ABSTRACT:
A database of interests is maintained in a distributed computing system to register the individual interests of users in centrally stored non-textual media files, such as digital voice, music, scanned-in image, and video files. Uniquely named piece table style persistent data structures are employed to give users controlled access to the underlying non-textual media files by embedded name reference to such piece tables in ordinary messages or text files, so a database of piece tables is also maintained. A garbage collector periodically enumerates the interest database to delete interest entries which have been invalidated. Aged piece tables are deleted from the reference database when there no longer are any recorded interests referring to them, and non-textual media files are deleted to reclaim the storage space allocated to them when there no longer are any piece tables referring to them.
