Leonardo service documents: with those not held

duckdb -csv -c "SELECT document_id, issuer, type_label, number, title, latest_revision, latest_revision_date, has_file
  FROM 'https://openairdocs.org/data/latest/service_document.parquet'
  WHERE issuer_kind <> 'authority'
    AND issuer_key = 'leonardo'
  ORDER BY type_label, number"

Prints the whole list as CSV. It reads the release’s Parquet files over HTTPS, so there’s nothing to download first. Install DuckDB to run it.

Run it at the DuckDB prompt, or in any tool that reads Parquet over HTTPS. More ways to query the release are on Use the data.
