Field	Type	Description	Constraints	Title
country_code	string	ISO 3166-1 alpha-2 country code — always SE	{ "pattern": "^SE$", "required": true }	Country Code
postal_code	string	5-digit Swedish postal code in NNN NN display format (space significant). Read via this descriptor or pass dtype=str.	{ "pattern": "^\\d{3} \\d{2}$", "required": true }	Postal Code
place_name	string	Postort (postal town)	{ "required": true }	Place Name
admin_name1	string	Län (county)	{ "required": true }	Administrative Name 1
admin_code1	string	ISO 3166-2:SE county code, SE- prefix stripped	{ "required": true }	Administrative Code 1
admin_name2	string	Kommun (municipality). Source-supplied for most rows; where the source left it blank, resolved from evidence already in the dataset or a corrections table — see README.	{ "required": true }	Administrative Name 2
admin_code2	string	Reserved — Sweden has no official municipality-level ISO code, and none is populated for this build.		Administrative Code 2
admin_name3	string	Reserved — not populated for Sweden (postort occupies place_name, the finest tier this source reaches).		Administrative Name 3
admin_code3	string	Reserved — not populated for Sweden.		Administrative Code 3
latitude	number	WGS84 latitude, decimal degrees, 5 dp — postal-code centroid, not building-level		Latitude
longitude	number	WGS84 longitude, decimal degrees, 5 dp — postal-code centroid, not building-level		Longitude
accuracy	string	Coordinate granularity tier — always AREA for this dataset (postal-code centroid, not GeoNames' numeric 1-6 scale)		Accuracy
alternative_city_name	string	Alternate postort spelling/name where the source supplies one		Alternative City Name

About this dataset

Sweden (SE): migration notes

Internal record of the P5 migration. This is a dated record (2026-10-05) and is not shipped in the zip.

Issue: pc-28e.7.50 (open, deferred)
Producer: none written. The descriptor keeps pipeline: producer: custom with refresh disabled, and the data stays as harvested from the live zip in 09d7c89.
Parity: not run (no producer).

Why it stays on live data

Live se.csv came from an external fedex-agents-prototype countries/SWE kommun-resolution build (commit 27401c7). That build is not in this repo.
The in-repo build_base.py is a GeoNames passthrough. Porting it would regress against live: about 3,055 blank kommun, 17 blank län, 47 kommun and 29 län reassignments, 45 name normalisations, accuracy AREA → numeric, and admin_code2 populated. It would also break the schema's required flags.
29 new GeoNames codes seen in the comparison are upstream drift.

Decisions

Decision	By	Basis
Defer: stay on live data	User, 2026-10-05	A faithful port of the in-repo builder regresses live

Open questions

Revisit if the kommun-resolution build is brought into the repo.

Provenance

Written 2026-10-05 from docs/parity/p5.md (batch sign-offs) and the bd notes on pc-28e.7.50.
