Preservation Metadata

DEFINITION:  A digital archival repository collects and maintains metadata that describes actions associated with custody of permanent records including an audit trail that documents preservation actions carried out, why and when they were performed, how they were carried out and with what results. A current best practice is the use of a PREMIS-based Data Dictionary to support an electronic chain of custody that documents authenticity over time as preservation actions are executed. Capture of all related metadata, transfer of the metadata to any new formats/systems, and secure storage of metadata are critical. All metadata is stored in the Preservation Description Information (PDI) component of conforming ISO 14721 AIPs.
 
 Level 0   Little or no preservation metadata is created, captured or maintained for electronic records.
 Level 1 Minimal preservation metadata is available to support electronic records in the archival repository.
 Level 2 A partially conforming ISO 14721 preservation metadata scheme (like Dublin Core) is in place for electronic records in the archival repository.
 Level 3 A preservation metadata schema is in place that includes a data dictionary that identifies ISO 14721 conforming comprehensive preservation metadata specifications. 
 Level 4 A PREMIS-based preservation metadata schema is in place that is continuously reviewed and updated to take into account new and different types electronic records that are transferred to an archival repository.

All metadata is stored in the Preservation Description Information (PDI) component of conforming ISO 14721 AIPs.

Level 0

Little or no preservation metadata is created, captured or maintained for electronic records.

Move to Level 1: Start to capture/record some preservation metadata elements (Reference Info, Context Info, Provenance Info, Fixity Info, or Access rights Info as included in PDI and defined in OAIS)

Jump to Level 2: Capture a standard set of metadata using a metadata schema such as Dublin Core. Use this to record/document file format integrity and provenance.

Level 1

Minimal preservation metadata is available to support electronic records in the archival repository.

Move to Level 2: Capture a standard set of metadata using a metadata schema such as Dublin Core. Use this to record/document file format integrity and provenance.

Jump to Level 3: Capture a standard set of metadata (such as with METS) that includes descriptive, administrative, structural, and preservation elements but is not entirely PREMIS based.

Level 2

A partially conforming ISO 14721 preservation metadata scheme (like Dublin Core is in place for electronic records in the archival repository.

Move to Level 3: Capture a standard set of metadata (such as with METS) that includes descriptive, administrative, structural, and preservation elements but is not entirely PREMIS based.

Jump to Level 4: Use a PREMIS based metadata schema and review it regularly, update as necessary.

Level 3

A preservation metadata schema is in place that includes a data dictionary that identifies ISO 14721 conforming comprehensive preservation metadata specifications. For example: The "Administrative Metadata" section in METS covers technical metadata, intellectual property rights, source metadata (provenance), and digital provenance metadata.

Move to Level 4: Use a PREMIS based metadata schema and review it regularly, update as necessary. 

Level 4

A PREMIS-based preservation metadata schema is in place that is continuously reviewed and updated to take into account new and different types electronic records that are transferred to an archival repository.
