OA/Free service

When we receive a request for a DOI, we check to determine if it is an OA/Free DOI, using internal checks and logic. If a DOI satisfies one or more of these checks, we skip sending the request to the publisher API and respond on behalf of the publisher.

For entitlements that have satisfied one of the following checks, the “source” key is set to oa_platform.

  • Has a previous publisher response indicated this DOI is OA/Free/Permfree?
  • Does the DOI have one or more licences that we know are OA?
  • Is the publisher this DOI belongs to OA only?
  • Does the DOI begin with a prefix that the owning publisher has designated as OA?
  • Does the DOI belong to an OA Journal?
  • Does the DOI belong to a journal registered with DOAJ?
