14. Digital Preservation Policies Policies based around simple three stage approach to preservation 1 – Archive . The objects cannot be preserved if they are not in the archive. 2 – Risk Management . Assessment of the likely preservation risk at ingest. Allow for pragmatic but proactive approach to individual preservation cases. i.e. file normalisation as part of ingest as prevention (e.g. Adobe PDF conversion) 3. Preserve . Provide method for migration/emulation on a per object basis. Original bit stream is main archive, and we are maintaining the method of preservation rather than carrying out transformation en masse
