Custody Documentation Reference Index (CDRI)
The Custody Documentation Reference Index (CDRI) is a structured reference system established to assign Unique Reference Numbers (URNs) to documented custody events.
A URN references a documentation event only.
It does not validate authenticity, ownership, valuation, legal rights, or regulatory compliance.
Purpose of the CDRI System
The CDRI system is intended to:
• Provide structured event referencing
• Improve documentation traceability
• Promote clarity in custody record identification
• Support structured archival referencing
The system does not replace institutional documentation systems.
Unique Reference Number (URN) Format
All CDRI-issued reference numbers follow a standardized format:
IACA-CDRI-YYYY-XXXX
Where:
YYYY = Year of reference issuance
XXXX = Sequential reference number
Example:
IACA-CDRI-2026-0042
Scope of Reference
A CDRI URN references a documented custody event submission only.
It does not constitute:
• Ownership registration
• Legal recordation
• Title confirmation
• Authenticity verification
• Market valuation
The URN functions solely as a documentation reference identifier.
Institutional Position
The CDRI system operates as a structured documentation reference mechanism.
It does not operate as a registry of ownership, authenticity database, or legal instrument.
All usage remains informational in nature.
