Just wondering anyone knows if there is a way you can update the timestamp in OAI-PMH? We are on version 220.127.116.11. Our Library catalogue is harvesting two of our locally hosted OJS3 journals via OAI-PMH. We are having some issues with a few older issues (they may have been batch uploaded in the past). The timestamp in the OAI for these older issues are updated whenever the OAI feed is accessed; hence stopping them to be harvested to our library catalogue. e.g., https://journals.lincoln.ac.nz/index.php/LPR/oai?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai:ojs.journals.lincoln.ac.nz:article/747
Thanks in advance.
