Potential Risks
Scholars Portal SP is in the process of generating digest values for content that was ingested before the repository adopted its fixity procedures. Until this process is complete, some files do not have digest values and are not candidates for regular fixity testing.
Scholars Portal SP does not generate digest values for its preservation metadata files. In other words, there is no fixity check for the fixity values. It should be noted, however, that these files are subject to the MarkLogic database's internal consistency checking.
Monitoring Commitments
Scholars Portal SP operates a rolling test of digest values. Fixity tests that produce a mismatch are automatically reported to staff through the repository's issue tracking system. See 5.1.1.3.1 for more information. SP staff monitor developments in mechanisms to measure the integrity of digital information and will upgrade the repository's procedures if necessary.
