When to assign a new DOI to an existing dataset?

Thanks, @dnoesgaard four your answer, Colombia is one of the nodes with Datacite credentials, thus we assign DOI’s at the IPT level, that’s also why we were interested in having external thoughts about the topic. Until now we have used only one DOI by resource, which I’m glad it looks like a good decision given your and Jorrit’s answer.

Thanks, @jhpoelen, the GBIF context you gave is very helpful for the question raised. On the other hand, I was unaware of the lack of power of DOIs to reliably cite specific dataset versions, and the references you mention open an interesting line of discussion.

I see two necessities,

  1. For data use and reproducible research, having DOI’s for each download covers the necessity of tracking a specific dataset (composed by parts of many resources) as the DOI’s are maintained if the downloaded dataset is cited, so at the data portal level, the current GBIF approach (I believe) is good enough.

  2. For data publishing at the IPT (or other publishing instance) level we may need to improve the system to have more reliable dataset identifiers given Jorrit’s references. Probably a very interesting topic to discuss in the context of Data papers, where the paper does refer to a very specific versión of the data.
