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.
SP's DIPs and AIPs are linked by having identical URIs. The preservation metadata component of the AIP records all events that occur to the object while in the repository, as well as makes reference to the location of the original SIP that is stored on disk and systematically backed-up. Preservation metadata, including provenance information is accessible to the user, where available, through the user interface.
