4.2.6.2 Execute documented processes for acquiring PDI
Status Ready for review
Compliance Rating Fully compliant
Responsible

The repository shall execute its documented processes for acquiring PDI.

Supporting Text

This is necessary in order to ensure that an auditable trail to support claims of authenticity is available, that unauthorized changes to the digital holdings can be detected, and that the digital objects can be identified and placed in their appropriate context.

Examples for Meeting the Requirement

Standard operating procedures; manuals describing ingest procedures; viewable documentation on how the repository acquires and manages Preservation Description Information (PDI); creation of checksums or digests, consulting with Designated Community about Context.

Discussion

PDI is needed not only by the repository to help ensure the Content Information is not corrupted (Fixity) and is findable (Reference Information), but to help ensure the Content Information is adequately understandable by providing a historical perspective (Provenance Information) and by providing relationships to other information (Context Information). The extent of such information needs is best addressed by members of the Designated Community(ies). The PDI must be permanently associated with Content Information.

Evidence

The proof is in using the webUI which shows that the processes have been executed: showing what preservation description information has been collected for each package.
