The actual development version is available at [https://git.fsfe.org/art1pirat/Archive-BagIt](https://git.fsfe.org/art1pirat/Archive-BagIt)

# Conformance to RFC8493

The module should fulfill the RFC requirements, with following limitations:

- only encoding UTF-8 is supported
- version 0.97 or 1.0 allowed
- version 0.97 requires tag-/manifest-files with md5-fixity
- version 1.0 requires tag-/manifest-files with sha512-fixity
- BOM is not supported
- Carriage Return in bagit-files are not allowed
- fetch.txt is unsupported

At the moment only filepaths in linux-style are supported.

To get an more detailled overview, see the testsuite under `t/verify_bag.t` and corresponding test bags from the BagIt conformance testsuite of Library of Congress under `bagit_conformance_suite/`.

See [https://datatracker.ietf.org/doc/rfc8493/?include\_text=1](https://datatracker.ietf.org/doc/rfc8493/?include_text=1) for details.
