The CoreTrustSeal Requirements are reviewed and updated if necessary every three years. To prepare the release of the CoreTrustSeal Requirements 2020–2022, a review and revision process was undertaken in several distinct phases. Feedback was included from applicants during past reviews, other communication and outreach activities, as well as an open review period that ran from 1 March 2019 to 31 May 2019. A WG of the CoreTrustSeal Board met face-to-face on 23–25 July 2019 to review each item of feedback, and incorporate them into revisions of the Requirements, Extended Guidance, and Glossary as necessary.
Given the feedback received and that past WDS and DSA repositories are continuing to transition to the CoreTrustSeal certification, the number, structure, and content of the Requirements remain fundamentally stable for 2020–2022. This stability enables the CoreTrustSeal Board to work to support a wider range of repository types and repository technical infrastructure providers in the future. It also provides an established baseline from which to consider other external demands on the CoreTrustSeal.
