About this dataset

Denmark (DK): 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.7.16 (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

The DAWA API (api.dataforsyningen.dk, dawa.aws.dk) permanently returns 410 Gone for postnumre, kommuner and regioner, so the old scripts/build_postal_codes_product.py can't fetch.
Successor: the Datafordeler DAR REST postnummer endpoint (services.datafordeler.dk/DAR/DAR/1/rest/postnummer, 200, no auth) has only postnr and navn. Municipality, region and geometry need other registers, and graphql.datafordeler.dk is 401 (needs credentials).
For a producer, the old builder's behaviour to keep: rows sorted by postal_code, CRLF in live, coordinates to 5 dp, accuracy AREA, and 8 municipality overrides (2770 3760 2610 2650 2605 2730 8970 4291).

Decisions

Decision	By	Basis
Live data unchanged meanwhile	Orchestrator, 2026-10-03	Plan D1
Defer under D1: stay on live data, no Datafordeler move for now	User, 2026-10-05	DAWA is gone; Datafordeler needs credentials plus a new licence check

Open questions

Revisit if Datafordeler credentials are obtained. That needs a new licence check for the Datafordeler registers (DAR plus whichever registers provide municipality, region and geometry).

Provenance

Written 2026-10-05 from docs/parity/p5.md and the bd notes on pc-28e.7.16.
