Sammlungen Online, Open Access, Wikimedia Commons

From Google's English:  "The National Museums in Berlin are now making high-resolution images of works from their 19 collections and institutes freely available on the new website sammlung.smb.museum . In addition, the possible uses of reproductions of public domain works will be fundamentally expanded and digital reproductions will be gradually made available via Wikimedia Commons. More than 270,000 objects from different eras and regions can already be discovered, researched and explored online." ...

Based on the most recent amendments to the Copyright Act and the Prussian Cultural Heritage Foundation's "Open Science Policy" , the State Museums in Berlin are opening up new potential for the use of their digital offerings. This enables the greatest possible access to object images and data on the cultural assets preserved in the collections of the National Museums in Berlin. Users are also offered extensive options for reusing the object images and data.

The permitted forms of use are easily recognizable through the use of Creative Commons licenses. A significant part of the object images will in future be marked with the "Public Domain Mark" and can therefore be used without any restrictions. The rights of third parties, "fair" principles and the "Care Principles for Indigenous Data Governance" are taken into account. The photo credits on the websites of the National Museums in Berlin will be successively converted to the new forms of use. Particularly high-resolution scans can be requested from the respective collections and institutes...."
