    OAI identifiers are unique identifiers minted cost-free by repositories. Ensure that your repository is correctly configured, enabling the CORE OAI Resolver to redirect your identifiers to your repository landing pages.

    OAI IDs provide a cost-free option for assigning Persistent Identifiers (PIDs) to your repository records. Learn more.
