To understand the impact of certification on repositories’ infrastructure, processes, and services, we analyzed a sample of publicly available TDR audit reports (n = 175) from the Data Seal of Approval (DSA) and Core Trust Seal (CTS) certification programs. This first longitudinal study of TDR certification over a ten-year period (from 2010 to 2020) found that many repositories either maintain a relatively high standard of trustworthiness in terms of their compliance with guidelines in DSA or CTS standards or improve their trustworthiness by raising their compliance levels with these guidelines each time they get recertified.
