• Adding new digital objects (unsponsored)
• Deleting digital objects (unsponsored)
• Redoing format identification/validation (version 1.6)

Full re-ingest

To be supported in version 1.6. Sends an AIP to the beginning of transfer to run all micro-services on AIP, and re-normalize for preservation and access if desired.

Re-ingest metadata only

Supported in version 1.5. Sends an AIP to the beginning of ingest to allow user to update metadata.

Re-ingest metadata and objects for DIP generation

Supported in version 1.5. Sends an AIP to the beginning of ingest to allow user to update metadata and normalize for access.

New micro-services

New micro-services for all workflows

• Retrieve AIP from archival storage
• Place AIP in active transfers for processing
• Extract AIP contents and run BagIt checks
• Add approve AIP re-ingest micro-service
• Re-use existing file UUIDs
• Identify new metadata files
• Validate schemas in new metadata files
• Update METS file
• Replace AIP

METS versioning

• Versioning will be captured via METS file updates.
• METS file updates will be handled through <status>, <created> and <groupID> attributes in the various METS sections. See for example Element <dmdSec> at http://www.loc.gov/standards/mets/docs/mets.v1-9.html.
• This means that there will always only be one AIP METS file, but it will contain both superseded and current metadata and versioning information for all updates.
