Term	Kind	Topic	What it is
Code List Governance	practice	Reference Data	Managing the small shared enumerations — currencies, country codes, statuses, product categories — whose uncontrolled change breaks systems quietly.
Identifier Reuse Hazard Code Recycling, Key Reassignment	concept	Reference Data	The silent corruption that occurs when a retired code or key is later assigned to a different real-world entity, so historical facts join to the wrong meaning with no error anywhere.
Reference Data	concept	Reference Data	The slowly-changing shared vocabularies — country codes, currencies, product categories, tax rates — whose inconsistency causes disproportionate trouble.
