New community resource: International Comparison of Recommended File Formats

The Open Preservation Foundation published, on 4 April 2022, a new resource that enables users to compare accepted and preferred file formats at a high level across different types of cultural and scientific institutions across the world.


Created by members at the National Archives of Estonia, and the National Archives of Denmark, the comparison of recommended file formats aims to inspire organisations that are getting started with, or are renewing their file format policy. It is not intended to be used alone as a policy. The current data was submitted by OPF member organisations or gathered from institutions that have published their policies openly online.
