4.6.2 - The repository shall follow policies and procedures that enable the dissemination of digital objects that are traceable to the originals, with evidence supporting their authenticity.
This is necessary to establish an auditable chain of authenticity from the AIP to disseminated digital objects.
Examples for Meeting the Requirement
System design documents; work instructions (if DIPs involve manual processing); process walkthroughs; production of a sample copy with evidence of authenticity; documentation of community requirements for evidence of authenticity.
Authenticity is not an ‘all or nothing’ concept, but is a matter of degree, judged on the basis of evidence. Thus the adequacy of the evidence is of key importance in assessing this requirement.
This requirement ensures that ingest, preservation, and transformation actions do not lose information that would support an auditable trail of authenticity between the original deposited object and the eventual disseminated object.
A repository should record the processes to construct the DIPs from the relevant AIPs. This is a key part of establishing that DIPs reflect the content of AIPs, and hence of original material, in a trustworthy and consistent fashion. DIPs may simply be a copy of AIPs, or may result from a simple format transformation of an AIP. But in other cases, they may be derived in complex ways. A user may request a DIP consisting of the title pages from all e-books published in a given period, for instance, which will require these to be extracted from many different AIPs. Or a repository may disseminate automatically generated transcripts of voice recordings. A repository that allows requests for such complex DIPs will need to put more effort into demonstrating how it meets this requirement than a repository that only allows requests for DIPs that correspond to an entire AIP.
This requirement is concerned only with the relation between DIPs and the AIPs from which they are derived; elsewhere the link between the originals SIPs and the AIPs is considered.
Content is disseminated from the APTrust archive upon a decision that a trigger event has occurred (see 4.3.4 and Definition of DIP). Under current configuration of access, APTrust does rebag content, but keeps all identifiers the same, and content in the data directory will always remain as it was sent to APTrust.
