Methodology of digital preservation audits with NDSA Levels

Abstract

NDSA Levels is a methodology created by the National Digital Stewardship Alliance (NDSA) at the United States to assess the level of digital preservation of a particular institution. Results of its application in 8 public and private organizations in Spain, Mexico, Brazil and Switzerland are presented. From this experience it is concluded that the NDSA Levels methodology is easy to apply and that its application besides alerting about the aspects not yet implemented, provides guidance on the technical actions that should be undertaken in the future within a preservation plan.
