OA Week 2012 has already generated several important OA mandates and mandate recommendations (from Hungary, Japan, Brazil, Ireland, France, Science Europe).

If your institution, funder or nation has adopted or proposed an Open Access Mandate, please register it in: 

ROARMAP 

(Registry of Open Access Mandatory Archiving Policies): 

http://roarmap.eprints.org

This will inform the world about OA progress and motivate others to adopt and announce their OA policies.
