Hi!Are all data that can be fetched via SPARQL CC0-licensed?Data in the main namespace, without the use of federation - yes.Federated data - https://query.wikidata.org/copyright.html, federatedendpoints can have different licenses, either CC0-like or CC-BY-SA like(I don't think we accepted any that have anything stricter than that)Category namespace - since it comes from Wikipedias, it's CC-BY-SA Iassume.--Stas Malyshevsmalyshev@wikimedia.org
