This page documents requirements for retrieving an Archivematica AIP from archival storage and re-ingesting it for further processing.
Use cases
- Updating DC metadata (version 1.5)
- Updating rights metadata (version 1.5)
- Adding new DC metadata files (version 1.5)
- Adding new submission documentation (unsponsored)
- Adding new digital objects (unsponsored)
- Deleting digital objects (unsponsored)
- Redoing format identification/validation/characterization (version 1.6)
- Redoing metadata extraction (version 1.6)
- Redoing preservation normalization (version 1.6)
- Generating new DIP (version 1.5)
- Running OCR on re-ingest (version 1.6)
- Rerunning other micro-services (Examine Contents, Transfer Structure Report) (unsponsored)
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.
Metadata re-ingest
Supported in version 1.5. Sends an AIP to the beginning of ingest to allow user to update metadata.
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- This means that there will always only be one AIP METS file, but it will contain both superseded and current metadata and versioning information for all updates.
- The original METS file will also be maintained as submission documentation
dmdSec
- The first dmdSec created will be marked as status="original", and updated/revised dmdSecs will be marked as status="updated". The timestamp (created="[date/time]") is also updated.
amdSec
techMD
- After re-ingest, the original techMD will contain the PREMIS:Object metadata and the status="superseded."
- The next techMD will be status="superseded" and contain the PREMIS:Object metadata generated on re-ingest, as well as all PREMIS events from each ingest and re-ingest. This shows the complete set of actions taken upon the objects since they came into the repository.
- The timestamp (created="[date/time]") is also updated.
