Yet another tool to validate BagIt formatted digital content according to RFC8493: The BagIt File Packaging Format (V1.0).

Written in Haskell, because I can™.

Roadmap

Validate packages

• [ ] Validate BagIt packages with SHA1, MD5, SHA256, SHA512
• [ ] Ensure bagit.txt, data/ and at least one manifest-<algorithm>.txt are present
• [ ] Ensure bagit.txt conforms with the spec
• [ ] Ensure tagmanifest checksums match if present
• [ ] Ensure all files listed in manifests are present
• [ ] Ensure payload checksums match
• [ ] Ensure all payload files are listed in all manifests if Bagit-Version is 1.0
• [ ] Quick validate based on Payload-Oxum if present
• [ ] Attempt to validate incomplete packages (by ignoring missing files)
• [ ] Complete packages using fetch.txt
• [ ] Normalize filenames before validating
• [ ] Permit other encodings than UTF-8 if specified in bagit.txt

Create/update packages

• [ ] Create new BagIt package
• [ ] Set metadata tags in bag-info.txt
• [ ] Update package
• [ ] Warn about problems with filename normalization

Misc

• [ ] Skip files matching a pattern when validating
• [ ] Parse and display tag file entries
• [ ] Update tag file entries
