According to BagIt spec 16 a bag is complete when:

  • Every required element is present (bagit.txt, data/, manifest-<alg>.txt)
  • Every file listed in every tag manifest is present
  • Every file listed in every payload manifest is present
  • (BagIt >= 1.0) every payload file is listed in every payload manifest
  • Every fetch file is present in the payload

A bag is valid when:

  • The bag is complete
  • Every checksum in every payload manifest and tag manifest has been successfully verified against the contents of the corresponding file.

Implement methods bag.isComplete and bag.isValid according to the statements above.
