Hello all,
I was about to upload a map exported from the main site (SVG using
Mapnik style) which I see is licensed under CC BY-SA 2.0
Wikimedia Common's upload page requires 2.5, 3.0 or 4.0 (using
https://commons.wikimedia.org/wiki/Special:UploadWizard )
Is this a problem?
No. The Creative Commons share-alike licenses contain an upgrade clause
(4.b of version 2.0) which allows you to CC BY-SA 2.0 content under "a
later version of this License with the same License Elements as this
License", i.e. CC BY-SA 2.5, 3.0 or 4.0.
