« Previous Version 4 Next » - The repository shall have documented processes for acquiring PDI.


When the SIP is first deposited into the repository, Scholars Portal's customized loader script decompresses it and records the file fixity information. All the publisher provided metadata for each file, including the PDI, is extracted and normalized to version 3.0 of the NIH Journal Archiving & Interchange Tag set and housed in the eJournal database. Each article is given a unique URI. From there it is accessed by the TDR loader script which creates the Preservation metadata. Scholars Portal Preservation metadata contains the Reference Information (URI), the Context Information (publisher provided bibliographic information and SP created linkages, TOCs, etc.), Fixity Information, and Provenance Information (created by SP in PREMIS vocabulary as 'events').

For a visual representation of these procedures please see the document below.
