ISO Mapping

This document defines how ISO codes (country and region) are mapped in the pipeline.

Countries

• ISO 3166-1 alpha-2 codes are stored in metadata.
• Example:
• Kenya → KE
• Nigeria → NG
• South Africa → ZA

---

Regions

• Regions are normalized but _raw values are preserved.
• Example normalization:
• Sub-Saharan Africa → Africa
• SSA → Africa
• North Africa → Africa
• Middle East and North Africa → MENA

• country_raw: as extracted
• country_iso: ISO alpha-2 code (future extension)
