B3.1 Repository has documented preservation strategies.
A repository or archiving system must have current, sound, and documented preservation
strategies. These will typically address the degradation of storage media, the obsolescence of media drives, and the obsolescence of Representation Information (including formats), safeguards against accidental or intentional digital corruption. For example, if migration is the chosen approach to some of these issues, there also needs to be policy on what triggers a migration and what types of migration are expected for the solution of each preservation issue identified.
Evidence: Documentation identifying each preservation issue and the strategy for dealing with that issue.
ICPSR documents this thoroughly on the Digital Curation portion of its web site.
