Fixity Working Group
The Fixity Working Group was originally established May 31, 2016 as a joint collaboration of the Standards & Practices Interest Group and the Infrastructure Interest Group in order to move forward with reccomendations from the Fixity Guidance Report and the NDSA National Agenda. The Fixity Working Group created the Fixity Survey as a way to address the “… clear need for use-case driven examples of best practices for fixity in particular system designs and configurations established to meet particular preservation requirements” raised in the 2015 NDSA National Agenda. The survey set a baseline for activities being done in 2016. Future work will build off of these initial results and work towards developing longitudinal studies.
The Fixity Working Group started up for the second time in April of 2021 and completed work in October 2021. The report and associated documents can be found on the 2021 Fixity Survey OSF site.

- A subgroup of people looked into vendor fixity requirements and produced Vendor Fixity: An Attempt at Definition a report of their findings for the NDSA Leadership. The goal was to determine if there was a simpler method by which potential users could do a cross comaprison of how various servies defined fixity.
