Integrity Pillar requirements
Pillar requirements for integrity mostly correspond to the requirements from the used functionality, but restore after a mass loss may introduce new requirements.
The integrity pillar requirements are mostly described in the functionalities used for bitpreservation: Get File, Put File, Replace File, Get File IDs and Get Checksums.
However, in case of mass loss of data, it will probably be necessary to have procedures to get a mass dump from one pillar, and ingest it in another. This needs to be further detailed, see Unresolved issues - Integrity.
