2 Summary of functional requirements
The following list summarises the VERS functional requirements for a system that preserves electronic records:
- The system must be able to export VERS Encapsulated Objects (VEOs) that satisfy the requirements of PROS 99/007 Specification 3, VERS Standard Electronic Record Format.
- Exported VEOs must contain the mandatory metadata and the conditional metadata (if the appropriate condition applies) according to PROS 99/007 Specification 2: VERS Metadata Scheme.
- Record content in the exported VEOs must be in one of the approved long-term preservation formats specified in PROS 99/007 Specification 4, VERS Long Term Preservation Formats, or a format otherwise approved by PROV
- Records (VEOs) exported to PROV must be exported using one of the approved media and mechanisms given in PROS 99/007 Specification 5, Export of Electronic Records to PROV.
- The system must manage the record while it is being held in the recordkeeping system such that it is possible to:
- demonstrate that the record is authentic
- demonstrate that a record has not been modified in an unauthorised fashion (i.e. that it retains integrity)
- modify a record
- document the history of the record
- copy the records to new storage media (also known as 'refreshing')
- reliably retain the record despite system failures and disasters
- export the records to another system.
