  "usageInfo": "The compilation of wilayas, dairas, communes, their names, postal codes and administrative codes is MIT. Four OpenStreetMap-derived parts are ODbL 1.0, (c) OpenStreetMap contributors: the 69 wilaya boundary polygons in data/geojson/wilaya-boundaries.geojson, and 323 commune centre coordinates taken from the commune's own admin_level=8 relation, 318 from its admin_centre node (56 on 2026-09-27, 189 on 2026-09-29, 5 on 2026-10-01 and 68 corrected on 2026-10-01 by the coordinate review, which writes a value only where independent sources vote for it) and 5 from the relation centroid in version 2.1.0, wherever those values appear, which includes 6 of the 69 wilaya capital points: a wilaya's latitude/longitude is the centre of its capital commune, so wilayas 7, 16, 25, 32, 52 and 61 carry one of these coordinates, while the other 63 wilaya capital points are not OpenStreetMap-derived. The fourth part is the osm_relation_id and wikidata values on the commune and wilaya records, read off the Algerian administrative relations in an Overpass capture with timestamp_osm_base 2026-09-29T12:54:47Z: 1,540 of the 1,541 communes and all 69 wilayas carry the id of their own relation, and 1,538 communes and all 69 wilayas carry the wikidata item that relation is tagged with, three of them from a second by-id capture (timestamp_osm_base 2026-10-02T10:16:05Z) of relations the first capture's tag filter excluded, and one (commune 3424) left null because an independent Wikidata check proved its relation's tag names a village inside the commune, in data/algeria.json, data/communes_w*.json and data/wilayas.json. The mirrored postal data under data/poste carries the terms @geoalgeria/poste itself states, Data © Algérie Poste; redistributed for reference, and is not MIT.
