About this dataset

Netherlands (NL) — internal licensing notes

Not mentioned in datahub-next#941 — no known licensing flag on this country. Source: converted from a FedEx-schema delivery (Netherlands_Delivery/Netherlands.csv, 467,630 rows) whose own base source is CC0 1.0 (public domain, no attribution needed). Two rows backfilled from the CBS woonplaatsen reference (CC-BY 4.0) would have dragged the whole file into an attribution obligation — those two rows are exactly the two asserting postalCode "00000" (no postal code), which don't belong in the postal-codes product anyway. Dropping them is correct on product grounds and keeps the published dataset cleanly CC0.

Session finding, 2026-08-19

Fixed nl/scripts/convert_from_fedex.py and siblings from hardcoded other-repo paths to self-contained. Confirmed the FedEx source file is real (45MB, not a stub) and re-ran the conversion against a fresh copy: 467,628 rows (2 dropped per above), byte-identical (MD5 match) to both the pre-existing local copy and live R2. Also confirmed the stale _meta/catalog.json entry for NL (which references a nonexistent nl-full.csv and claims 4,334 rows — off by two orders of magnitude from the real 467,628) is an index-only defect, not a data problem — this pipeline and the live nl.csv are both fine, only the storefront catalogue index needs a refresh.

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