NoeFlandre/osm-polygon-wikidata-only

OSM polygons tagged with a wikidata=* reference, enriched with Wikidata descriptions and Wikipedia article text for every valid language-Wikipedia sitelink, with full text and no per-QID article cap. One PBF produces three parquet files in this Hub:

• polygons/<stem>.parquet — one row per polygon
• articles/<stem>.parquet — one row per unique Wikipedia article
• polygon_articles/<stem>.parquet — many-to-many link table

osm_type	OSM element type: way or relation.
osm_id	OpenStreetMap numeric identifier of the element.
wikidata	Wikidata Q-id from the OSM wikidata=* tag.
name	Convenience: tags.name if present, empty string otherwise.
tags	Deterministic JSON object of all OSM tags except wikidata.
tag_keys	Deterministic JSON list of sorted OSM tag keys.
tag_count	Number of OSM tags (excluding wikidata).

has_english_wikipedia	True if en is among the available languages.
has_french_wikipedia	True if fr is among the available languages.
text_available	True if at least one linked article has non-empty full text.
best_language	Deterministic preferred language code (e.g. en).
extraction_version	Package version that produced the row.
