Boston College packaged 183 GB of digital newspaper content using BagIt. This package was then split into smaller 30 GB archival units for preservation storage using the BagIt Java Library. These smaller archival units then had their checksum manifests validated against the original manifest using custom scripts built in the project.
After a successful ingest these smaller BagIt units were exported, rebuilt, and validated as the original 183 GB package using some additional custom scripts built in the project. The rebuilt BagIt package was then returned to Boston College who were able to validate checksums using the BagIt tools.
