Automatic digital preservation on ingest

Audience: archivist, digital preservation officer, sysadmin

When you commit a Data Ingest session, every digital object it creates is automatically run through a digital-preservation baseline - the same idea as an Archivematica transfer running its micro-services. You do not have to switch anything on: it happens on every ingest so your objects are preserved and auditable from the moment they land.

What happens to each ingested object

  • Fixity checksum (SHA-256) is generated and stored. This is the baseline that future fixity checks compare against to detect bit-rot or tampering.
  • Format identification records the file format (PRONOM) in the format registry, so obsolete or at-risk formats show up in preservation reports.
  • Virus scan runs when a scanner is available.
  • A PREMIS "ingestion" event is logged for the object, so there is a permanent, standards-based record that it was ingested, when, and by which process.

These steps are best-effort: if one of them cannot run (for example a scanning tool is offline), the object is still ingested and the failure is logged for follow-up - your ingest never fails because of a preservation step.

Where to see the results

  • Central Dashboard → Data Ingest card shows live ingest counts and a link confirming "Ingested objects are auto-preserved".
  • Preservation Dashboard → PREMIS Events lists the ingestion event for each object.
  • Preservation Dashboard → Fixity Verification lists the objects that now carry a checksum, and lets you run/verify fixity over time.
  • Preservation Dashboard → Formats / At-Risk Formats shows the identified formats and flags ones that need migration.

Requirements

  • The Digital Preservation module must be installed (its tables must exist). If it is not installed, ingest still works normally - the preservation baseline is simply skipped.
  • PREMIS XML export
  • Preservation packages (BagIt / AIP)
  • Data Ingest user guide
