--- Comment #8 from Davide Cavalca davide@cavalca.name --- Update on the datafiles: - upstream is replacing lena.tif with a free image in https://github.com/Mathics3/mathics-core/pull/731 - Namespaces.xml is actually W3C, which is ok, see https://github.com/Mathics3/mathics-core/pull/733 - Legal confirmed in the linked issues that all other data files can be considered either Public Domain or not actually copyrightable, so we're good there
