Hi OSI reviewers!

I would like to submit the National Institute of Standards and Technology (NIST) Software license for review to be included in your list.  This is the primary license that NIST staff are expected to use when releasing software.

The license complies with the Open Source Definition, including the OSD 3, 5, 6 and 9 criteria.

There are numerous projects using the NIST software.  For instance, there are 1.3K repositories at https://github.com/usnistgov that should all be using the license.  As such, it falls under the legacy category.

The NIST license is also listed on the main NIST website https://www.nist.gov/open/copyright-fair-use-and-licensing-statements-srd-data-software-and-technical-series-publications, and has an SPDX listing https://spdx.org/licenses/NIST-Software.html. Under both sites, it is titled "NIST Software License"

Thank you for your time and consideration!

Sincerely,

Lucas Hale
