The document discusses the concept of openness in museums and cultural institutions. It argues that as the world becomes more connected through technology, cultural resources should also become more openly accessible and available for reuse. However, many institutions still enclose resources through lack of digitization, restrictive terms of use, or concerns over control, revenue, and resources. The document advocates for a more open approach in line with concepts like open access, open data, and Creative Commons licensing to promote broad participation in and benefit from cultural and scientific resources.
