Partial re-ingest

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• This means that there will always only be one AIP METS file, but it will contain both superseded and current metadata and versioning information for all updates.
