RFC 8493 validation
Completeness, payload checksums, Payload-Oxum and tag manifest; flags missing or extra files.
Integrity
BagIt package
The BagIt module validates BagIt (RFC 8493) preservation packages — folder or .zip: structure, completeness and payload checksums. For the CERTO and LOCUS evidentiary bundles it performs end-to-end validation: Ed25519 signature, RFC 3161 timestamps and CASE/UCO metadata, with a PDF report.
What it does
What the BagIt package module does
CERTO/LOCUS bundles
Verifies the Ed25519 signature, the media hash, the RFC 3161 timestamps and the CASE/UCO metadata of the bundle.
Folder or .zip
Analyses a bag as a folder or as a .zip archive, without unpacking it by hand.
PDF report of the outcome
Summary of validity, passed checks, anomalies and bundle notes in a case-ready report.
Step by step
How it works
- Drop the bag (folder or
.zip) into the module. - Probatio validates structure, checksums and — if it is a CERTO/LOCUS bundle — signature and timestamps.
- It generates the PDF report with the full outcome.
FAQ
Frequently asked questions
What is a BagIt package?
BagIt (RFC 8493) is a packaging standard for data preservation and transfer: the files (payload) come with checksum manifests and metadata, so integrity is verifiable at any time.
Can I verify the bundles produced by CERTO or LOCUS?
Yes: for CERTO/LOCUS evidentiary bundles, Probatio performs end-to-end validation — Ed25519 signature, media hash, RFC 3161 timestamps and CASE/UCO metadata — in one click, with a PDF report.
Do I need to unpack the .zip?
No: Probatio analyses the bag both as a folder and as a
.zip archive, without unpacking it by hand.
