In April/May 2020 the Confederation of Open Access Repositories (COAR), in consultation with cOAlition S, conducted a survey of repository platforms in order to assess their current ability and intention to support Plan S requirements, and to identify any specific challenges related to their implementation. The survey found that most repository platforms already support compliance with Plan S mandatory criteria and, in the few cases where the platform does not, there are plans to adopt this functionality. In addition, many of the highly recommended criteria are also already supported by the platforms. In order to support compliance with Plan S, repository software platforms, repository managers and researchers (who use the repositories) will need to be aware of the requirements and, in some cases, adopt new practices and functionalities. As a next step, COAR and cOAlition S will continue to work together to ensure that repositories are well represented and develop more detailed guidance that assists them in supporting the major functionalities envisioned in Plan S.
cOAlition S is delighted that the findings of the survey indicate broad alignment with Plan S requirements. Such alignment significantly contributes towards cOAlition S funder grantees being able to publish in their journal of choice via the Plan S Option 2 repository route (see Guidance on the Implementation of Plan S).
