Adding DOI year cutoff

Hello Beghelli, Thanks for your answer. We now want to select that all our past articles aren’t going to have DOI. How could we modify this option for all the articles through a database instruction. How are the DOI stored? is there a table in OJS database with that information? I appreciate very much your help. Best regards,
