ISO 16363 Reminds us that much of digital
preservation readiness is not technical – it’s organizational
Level 1 (Protect) Level 2 (Know) Level 3 (Monitor) Level 4 (Repair)
Storage and Geographic
Location
• 2complete copies not collocated
• Get media off diverse storage media and into a system
• At least 3 complete copies• At least 1 in different
geographic location• Document storage system,
media, and what’s needed to use them
• At least 1 copy in location w different disaster threat
• Obsolescence monitoring process for storage system and media
• At least 3 copies in locations w different disaster threats
• Comprehensive plan to keep files and metadata on currently accessible media or systems
File Fixity and Data Integrity
• Fixity check on ingest if checksum provided w content
• Create fixity info if not provided on transfer
• Check fixity on all ingests• Use write-blockers w original
media• Virus check high-risk content
• Fixity checks at regular intervals
• Maintain fixity logs and supply audit on demand
• Virus check all content• Ability to detect corrupt
data
• Check fixity in response to specific events/activities
• Ability to replace/repair corrupted data
• Ensure no one has write access to all copies
Information Security
• Identify who has read, write, move, and delete authorizations
• Restrict who has those authorizations to individual files
• Document access restrictions for content
• Maintain logs of who performed what actions on files, incl. deletions and preservation actions
• Perform audit of logs
Metadata• Inventory of content and its
storage locations• Ensure backup and non-
collocation of inventory
• Store admin metadata• Store transformative
metadata and log events• Store standard technical
and descriptive metadata• Store standard preservation
metadata
File Formats• Encourage creators to use open
formats and codecs when possible
• Inventory of file formats in use • Monitor file format obsolescence issues
• Perform format migrations, emulation, etc. as needed
