The updated plan was released yesterday.
From the Executive Summary:
Since the release of the NSF Open Government Plan 1.0 in April 2010, the agency has connected the plan to its then most recent strategic plan. Consequently, “Investing in Science, Engineering and Education for the Nation’s Future — NSF Strategic Plan for 2014-2018″1 is reflected in this most recent version of the NSF Open Government Plan.
With respect to making its data and information available, NSF’s key principle in executing all of the elements of the NSF Open Government Plan is: Unless shown otherwise, the default position will be to make NSF data and information available in an open machine-readable format.
This updated version of the plan (released in September 2016) is the result of NSF’s continued commitment to open government, and reflects the agency’s intent to revise and improve the original, Version 1.0 plan, including new flagship initiatives. To ensure steady progress, NSF welcomes comments and suggestions on this version of the open government plan at firstname.lastname@example.org. NSF, from its senior management through the entire Foundation staff, is committed to the principles set forth in this plan. Indeed, this is reflected in the NSF strategic plan for 2014-2018 where it states: “NSF is committed to the principles underlying open government, including transparency, public participation, and collaboration with other government agencies and private institutions.”
