To support open access to peer-reviewed articles, cOAlition S has published detailed technical conditions for scientific journals, publication platforms and repositories.
The coalition has also develop the Journal Checker Tool to help researchers supported by funder compliant with Plan S. The tool allows researchers to check whether a scientific journal or publishing platform complies with Plan S. In the case of non-compliant journals, the tool also provides guidance on how to implement immediate self-archiving as enabled by Plan S.
The Journal Checker Tool was opened in late 2020 and is still in beta. Researchers and other members of the scientific community using the Journal Checker Tool may send requests for supplementations and corrections through the portal.
If a scientific journal published in Finland meets all the other conditions set out in Plan S for the implementation of open access, the journal need not be registered or in the process of registering in the Directory of Open Access Journals (DOAJ). This especially applies to journals that have not made other material than peer-reviewed articles open access.
The Journal Checker Tool does not contain information on repositories compliant with Plan S. The Research Council of Finland considers that all repositories operating in Finland with the support of Finnish universities and government research institutes fulfil these conditions.
