Policy
Persistence policy
A DRI, once issued, is never deleted and never reassigned to a different object. Withdrawn objects resolve to a stable tombstone page rather than disappearing. Resolution is free and unauthenticated, permanently.
Portability & succession
The full identifier-to-target map and metadata are exported nightly in open formats (JSON and CSV) and held so that the registry can be reconstituted by a successor steward if DRI ceases to operate.
A machine-readable copy of this statement is included in every
?info response and in every nightly escrow dump.
