🧾Industry Reference Data

NEW

Also known as: External Reference Data, Standard Code Sets

Externally maintained code lists and classifications from standards bodies or regulators that enable interoperability across organizations and systems.

DESCRIPTION

Industry reference data comprises standardized codes like country (ISO 3166), currency (ISO 4217), disease (ICD-10), and industry classifications (NAICS). Maintained by recognized authorities, these codes support cross-organizational data exchange and compliance. Adopting them reduces mapping overhead and ambiguity. Organizations often map internal codes to these standards. Proper governance tracks versions and licensing, and ensures upstream/downstream alignment.

ALTERNATIVE DEFINITIONS
