About this dataset
Italy (IT) — internal licensing notes
Not mentioned in datahub-next#941 — no known licensing flag on this country. Source: GeoNames IT postal export, CC BY 4.0.
Session finding, 2026-08-19
Fixed it/scripts/ from hardcoded other-repo paths to self-contained.
Verified with a cold fetch (cached source deleted first): rebuild is
byte-identical (MD5 match) to both the pre-existing local copy and live R2,
18,415 rows. Cleanest of the countries audited this session — no data-quality
issues found in the existing R2 copy.
No licensing review beyond confirming GeoNames CC BY 4.0 as the source — this was a code-reproducibility audit, not a licence audit.
