Concepts
Foundations of the Philippine Standard Geographic Code (PSGC): what it is, the administrative hierarchy, the rphicmsgb hierarchy indicator, data models, and package architecture.
Explanations that deepen your understanding of the data and how the package works. Read these when you want the “why”, not just the “how”.
Foundations
- PSGC overview — what the PSGC is, the PSA source, the 10-digit code.
- Administrative hierarchy — region → barangay, HUC / ICC / component city distinctions.
- Hierarchy indicator (
rphicmsgb) — the 9-char level indicator explained.
Data & internals
- Data models explained — the three JSON shapes (nested / extended / flat) compared.
- Architecture — how the package works (DataManager, cache, plugin join).
