Regularly collecting information about the files in the various pillars, and ensuring that the files are consistent.

TODO: Obsolete, should be rewritten.

The processes of active bit preservation are essential for true bit preservation in the National Bit Repository. Thus, having a process implement these processes for every Service Level Agreement should be considered essential. This can be achieved, either by deploying the client developed for the National Bit Repository, or by implementing a different process for integrity checking.

The protocol contains functionality for listing files, retrieving checksums of files in pillars, and replacing damaged files that can be used to implement this. This functionality area describes the communications and processes needed to ensure active bit preservation.
