I had similar problems just the other day. There is some code commented out in dspace-api/src/main/java/org/dspace/identifier/doi/DataCiteConnector.java which will log details of the document being sent at DEBUG level. You could uncomment that code, rebuild, update, and tweak config/log4j.properties to set log4j.logger.org.dspace.identifier.doi.DataCiteConnector = DEBUG
A simpler way, if you're comfortable with network troubleshooting tools, would be to capture the exchange with host mds.datacite.org using something like tcpdump or Wireshark. (Probably this is what I should have done.) org.dspace.identifier.DataCiteXMLCreator can be run via 'bin/dspace dsrun' to show what that code would produce, but it may not be precisely the same document. I didn't learn anything from using it, but that may be because I hadn't figured out what to look for until I had given up on it and switched to using the debug code noted above. I don't know of anything built-in that one could just turn on to dump the live exchange. I think I will work up and submit a patch to permanently uncomment the debug code in DataCiteConnector. -- All messages to this mailing list should adhere to the DuraSpace Code of Conduct: https://duraspace.org/about/policies/code-of-conduct/ --- You received this message because you are subscribed to the Google Groups "DSpace Technical Support" group.
