Reusing our data
The data files carry the licence of their sources:
- Files on how MEPs and groups voted contain data from HowTheyVote.eu and are published under the ODbL 1.0. Credit HowTheyVote.eu and Parliament Radar. A database you publish that is derived from these files must also be under the ODbL.
- Files built only from the Parliament's Open Data Portal (items voted, results, dossiers, agenda) are published under CC BY 4.0. Credit the European Parliament and Parliament Radar.
Each file states its sources, its licence and its collection date at the top.
Reusing our texts and charts
Texts and charts of Parliament Radar are published under CC BY 4.0. You can reuse them, including for commercial purposes, if you credit "Parliament Radar by Parleon" with a link to the piece and say if you changed anything. Keep the source line of each chart. Reuse must not suggest that Parliament Radar or Parleon endorses you or your use.
Each vote page also offers a card you can embed on your own site. The card carries its own credit, "Parliament Radar by Parleon, CC BY 4.0; data: European Parliament, HowTheyVote.eu (ODbL)", and a link back to the vote. It sets no cookies and loads no third-party scripts.
Content from the European Parliament keeps its own terms. The names and logos of Parliament Radar and Parleon are not covered by this licence.
