4.5.3 - The repository shall create bi-directional linkages between each AIP and its descriptive information.


Each Scholars Portal AIP contains its own Descriptive Information in the Preservation Metadata which links to the Content Information on disk. The Content Information's metadata contains links to the Preservation metadata stored in a different database.

ResponsibilityAt the core of every SP AIP is the preservation metadata which contains a version of the CDO's Descriptive Information. A unique URI is used to locate the preservation metadata in the TDR database, the same URI can also be used to retrieve the full Descriptive Information of the AIP located in the ejournals database.
