Field	Type	Description	Constraints	Title
country_code	string	ISO 3166-1 alpha-2 country code — always MY	{ "pattern": "^MY$", "required": true }	Country Code
postal_code	string	5-digit Malaysian postcode.	{ "pattern": "^\\d{5}$", "required": true }	Postal Code
place_name	string	City/town — the tier postcodes are assigned at.	{ "required": true }	Place Name
admin_name1	string	Negeri (state) / Wilayah Persekutuan (federal territory).	{ "required": true }	Administrative Name 1
admin_code1	string	ISO 3166-2:MY code, MY- prefix stripped.	{ "required": true }	Administrative Code 1
admin_name2	string	RESERVED — not populated. No licence-clean source currently maps place_name to a district (daerah); see project notes.		Administrative Name 2
admin_code2	string	RESERVED — not populated.		Administrative Code 2
admin_name3	string	RESERVED — not populated. No licence-clean mukim source was found; Malaysia's Copyright Act 1987 s.11 grants copyright to government works by default, unlike some other countries in this pipeline.		Administrative Name 3
admin_code3	string	RESERVED — not populated.		Administrative Code 3
latitude	number	WGS84 latitude, decimal degrees, max 5 dp. From GeoNames, joined by postal code.		Latitude
longitude	number	WGS84 longitude, decimal degrees, max 5 dp. From GeoNames, joined by postal code.		Longitude
accuracy	string	GeoNames accuracy of latitude/longitude. GeoNames documents 1=estimated, 4=geonameid, 6=centroid of addresses or shape; other values (e.g. 3) occur upstream without documentation. Empty where GeoNames gives none.		Accuracy
alternative_city_name	string	RESERVED — not populated on this build pass.		Alternative City Name

About this dataset

Malaysia (MY) — internal licensing notes

Not mentioned in datahub-next#941 — no known licensing flag on this country. Sources: MCMC Postcode Dataset via data.gov.my (CC BY 4.0 — postal code, state, city) + GeoNames MY (CC BY 4.0 — coordinates, joined by postal code only; no admin2/admin3 data of its own).

Session finding, 2026-08-19

Fixed my/scripts/ from hardcoded other-repo paths to self-contained. Two real gaps closed, not just paths — this pipeline never had these steps, it always assumed pre-fetched/pre-packaged files existed on disk:

Wrote fetch_source.py (didn't exist) to download both sources fresh.
run_qa.py now builds my.zip and writes validation_report.json into the delivery folder — publish_r2.py requires both, nothing produced them before.
Added the buyer-facing README as a committed static template.

Verified end-to-end from a fresh fetch: 2,931 rows, 16/16 states (exact match). Final my.csv MD5-identical to live R2 (8819f4853269ae71df5204b7771db78d, 158,936 bytes).

No further licensing review — this was a code-reproducibility audit.

CLOSED — 2026-08-24 (datahub-next#941 §4)

Added standalone my/ATTRIBUTION.txt (MCMC/data.gov.my CC BY 4.0 + GeoNames CC BY 4.0, explicit no-share-alike-sources note) — now in R2 and inside my.zip. build_deliverable.py updated to write it, run_qa.py updated to zip it, on every run. _meta/catalog.json's MY entry rebuilt to include it. No pre-existing defect found.
