About

This file hosts examples of cases where research-relevant databases and similar infrastructure have switched to another license type (usually a more open or less open one) or to the CC0 license waiver. Changes of the license version (e.g. the Wikimedia Foundation changing their default license from CC BY-SA 3.0 to CC BY-SA 4.0) are not included here.

This list is very incomplete — additions and corrections are most welcome.
