Confederation of Open Access Repositories (COAR) Survey Finds No Large Barriers For Repository Platforms in Complying with Plan S

From the Confederation of Open Access Repositories (COAR):

One of the routes for complying with Plan S is for authors to make the final published version (Version of Record, VoR) or the Author’s Accepted Manuscript (AAM) openly available with an open license in a Plan S compliant repository with immediate OA from the date of publication.

In April/May 2020 the 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 currently support compliance with Plan S mandatory criteria and, in the few cases where they do not, there are plans to adopt this functionality. In addition, many of the highly recommended criteria are also already supported by the platforms. As a next step, COAR and cOAlition S will continue to work together to ensure that repositories are well represented and to develop more detailed guidance that assist 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).
