What ISO 14721 (OAIS) requires
Compliance with the ISO 14721 reference model mandates the establishment of a comprehensive framework for long-term digital preservation and access. An organization must first fulfill the `requiresDesignatedCommunityDefinition` prerequisite, explicitly identifying the user base for whom information is being preserved. The entire archival lifecycle is governed by strict procedural controls, as outlined in several key information science texts. Ingest processes demand a `requiresSipToAipTransformation`, converting submission packages into robust archival information packages, where each `aipHasUniquePersistentIdentifier` is assigned for unambiguous tracking. To maintain integrity, `fixityChecksScheduled` must be performed regularly, and a complete `requiresAuditTrailOnAip` must log all modifications. Preservation Description Information is critical; `requiresPdiVerification` is mandatory and must achieve a `minimumPdiCompletenessScore` of four. The system's preservation strategy is proactive, where the `mandatesPreservationPlanningFunction` necessitates continuous `requiresTechnologyWatchMonitoring` to mitigate format obsolescence. Crucially, a `maxAcceptableInformationLossRatio` of zero establishes a no-tolerance standard for data corruption. For user access, a governed `requiresAipToDipTransformation` process prepares dissemination packages from the archival master, while a stringent `accessControlPolicyEnforced` policy protects information according to its classification. This holistic approach, grounded in established digital curation principles, ensures information remains independently understandable and available over extended periods.
