On Grand Paris Sud Open Data, a majority of datasets here declare no licence at all. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 151 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially; 9% carry a share-alike condition, so work built on them has to be published under the same terms. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
61 of 100 sampled declare no licence and stay link-only; the licensed remainder is Licence Ouverte v2.0 and ODbL. Connected for the licensed portion — check undeclared_share before relying on it.
