18.104.22.168 PDI is persistently associated with Content Information of AIP
22.214.171.124 - The repository shall ensure that the PDI is persistently associated with the relevant Content Information.
The CLOCKSS archive has a single class of AIP, called an Archival Unit (AU), documented in Definition of AIP. This document describes how a content object is named, and how its content and metadata are stored together. It also describes how the various PDI elements are encoded in the name and metadata of each content object within each AIP (AU) during the creation of that content object from a SIP.
