The UMB Digital Archive provides bit preservation for all files. Bit preservation ensures that a file remains exactly the same over time. Functional preservation, the ability to use a file in the future in the same way that it is used currently, can only be guaranteed for supported formats.
- Supported formats will be functionally preserved using either format migration or emulation techniques.
- Known formats are those that we can’t promise to preserve (e.g., proprietary or binary formats) but which are so popular that we believe third party migration tools will emerge to help with format migration.
- Unsupported formats are those that we don’t know enough about to do any sort of functional preservation.
Please see the Preservation FAQ for a further discussion of this policy.
