Hi, thanks for the answer. I am sure DSpace was running (but will check again to make sure there were no errors at that moment). I used exactly the steps from the guide I linked. The only unclear step is modifying the config.dct file (number 4). There are several places with mentioned handle. I modified all of them. It could be helpful to make that step more clear or perhaps include example of the file before and after with some specific handle.
I understand that handles will not be resolved on https://hdl.handle.net and I am completely fine with it. If there could be more specific instructions about the config.dct file, it would certainly be helpful. If that does not help, I can send more data to try and pinpoint the issue.
