CC BY-NC
Non-commercial only — which the Open Definition does not count as open at all. A catalogue published this way is closed to exactly the reuse that would give it reach.
How this list is decided. Membership is not a field an editor set: it is every published entry whose own text names CC BY-NC, matched at build time, with the sentence printed under each row so you can judge the match yourself. 6 entries in 5 cities.
✔ Every published entry is checked against the public sources it cites before publication.
Where it appears in the atlas
The license_id facet returns CC-BY-4.0 1181, CC-BY-SA-4.0 419, CC0-1.0 103, notspecified 52, CC-BY-NC-ND-4.0 36, CC-BY-NC-SA-4.0 29, CC-BY-NC-4.0 24, other-open 19, odc-odbl 10, cc-nc 7, other-closed 3, and ODC-BY-1.0, ODbL-1.0, gfdl, other-pd and uk-ogl at 1 each — summing to 1888.
Open-data check, fetched 26 July 2026: 34 datasets, licensed CC BY 4.0 (20), CC BY-SA 4.0 (12) and CC BY-NC-SA 4.0 (2) — the first non-commercial licence encountered in this atlas's licence series.
A civic initiative, not the operator, released the only machine-readable Cairo Metro feed for Open Data Day Cairo 2016, licensed CC BY-NC 4.0, with the README caveat that 'All data related to schedules and dates are estimations'.
929 datasets on 7 August 2026 and not one without a named licence: 488 unversioned 'Creative Commons Attribution', 411 'CC-BY-4.0' with an empty licence URL, 27 CC0 and 2 CC BY-NC.
Confirms the facet label is not a cataloguing artefact: the records carry license_title 'Creative Commons Non-Commercial (Any)' and license_url pointing at the CC BY-NC 2.0 deed.
The public face is now city channels: dashboards are shared through Tartu's ArcGIS portal, and on 28 August 2026 Estonia's national open-data portal listed 29 datasets from Tartu city government, 28 of them under CC BY-SA 3.0 and the one pointing at the city's spatial-data hub under non-commercial CC BY-NC 3.0.
