We need to ensure that all published datasets have a DOI minted

Thats a test we've never done before. I just did it and discovered 2 datasets that has indeed been published in GigaDB without the DOI being minted at DataCite (100823 & 102585) I have now fixed those, and can confirm that (as of 10 Dec 2024) every published dataset in GigaDB has a corrosponding DataCite entry.
