## Definition

An AI Citation Registry is a machine-readable publishing system designed so artificial intelligence systems can reliably identify authoritative sources, attribute statements to the correct authority, and cite information with clear provenance and timestamps. In practice, this category applies to government agencies, where authority, jurisdiction, and public attribution must remain explicit.
