Data quality assurance is a fundamental issue for repositories that seek to ensure trust in their services. This workshop focused on measures research data repositories undertake to ensure data quality. The objective of this workshop was to raise awareness and make the various activities repositories perform to assure, assess, and improve data quality visible. The workshop was organized by Humboldt-Universität zu Berlin in collaboration with CoreTrustSeal and the Helmholtz Open Science Office and took place on October 5, 2022, 12:00-15:30 UTC.

The workshop consisted of three parts. It started with presentations of a survey on research data quality assurance at repositories conducted in 2021 as part of the re3data COREF project as well as lessons from the CoreTrustSeal consultation processes. Operators of repositories with different scopes presented their approaches to quality assurance. Based on this input, we discussed options for making information on data quality assurance visible at the level of repositories.

Results of the discussion are documented and shared with the public to be reused by repository services such as re3data, CoreTrustSeal, as well as other community initiatives.
