OpenData NCA: a clean licence on a catalogue that stopped growing
This overview was generated with AI from the public sources listed below and checked against them before publication. It has not had a complete human fact-check — treat it as a starting point and follow the sources.

The Métropole Nice Côte d'Azur runs a shared open-data portal on CKAN and Drupal, pooling data from the Métropole, the Ville de Nice, the tourism office, the transit operator Régie Ligne d'Azur and INSEE, and publishing everything under the Etalab Licence Ouverte. Queried on 10 August 2026 the catalogue held 268 datasets and every single one named that licence — a completeness few French portals match. The composition is less flattering: 96 of the 268 are INSEE statistics republished, against 89 from the Ville de Nice and 68 from the Métropole. The oldest datasets were created in April 2014 and the newest in June 2023; the live transit feeds have since moved to the national access point transport.data.gouv.fr, where the Métropole has published GTFS, NeTEx, SIRI and real-time GTFS-RT vehicle positions since June 2025.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
Self-audited through the portal's own CKAN API on 10 August 2026: 268 of 268 datasets carry the Licence Ouverte, and none carries a non-commercial or no-derivatives restriction. Publication activity is another matter — no dataset has been created since June 2023, and only 23 records were touched in 2026. The dataset billed as a "daily GTFS export" of the Lignes d'Azur network was last built on 9 May 2026, and the service calendar inside the file expired on 5 July 2026.
🎓 Lesson
A licence audit and a liveness audit answer different questions. Nice passes the first cleanly and fails the second on its own portal — while the data that has to stay current is current somewhere else, because French transport authorities are obliged to publish it on the national access point. Portals do not usually announce that they have stopped; you have to open the file and read the dates.
