The Swedish National Heritage Board has had an internal policy promoting the use of CC BY, CC0 and PDM since 2017 but today they communicated internally in a very forceful way. Part of the message (my translation from Swedish):
"Employees may not in their service use others copyrighted photographs that cannot be marked with CC BY, CC0 or PDM.
Material that cannot be marked with PDM, CC0 or CC BY shall not be digitized or published."
While it may not change their output much (they are already among the best in Sweden) I suspect this will send strong signals in the Swedish GLAM sector.
