I am familiar with the ESIP data citation recommendation that talks about "major" vs "minor" versions, but I am curious about how this is actually being implemented. <br></div><div><br></div><div>Does your repository assign DOIs for each denoted version, e.g. version 1, version 2, etc? Do you assign DOIs for incremental version changes, e.g. version 1.2 or version 2.3? What constitutes a version change in these cases? Does anybody assign DOIs to any change at all regardless of how large (e.g. a wording update in metadata)? Does anybody not assign new DOIs regardless of any versioning or dataset changes?</div><div><br></div><div>I'm asking because we are bringing in a fairly complex group of datasets into one of our NCAR repositories, and tracking versions is not at all straightforward. Since we intend to assign DOIs to the data, we're working through the above scenarios with no clear optimal outcome yet.</div><div><br></div><div>Any input on how you are actually implementing the ESIP recommendations (or others) on this would be much appreciated,</div><div><br></div><div>Best,</div><div>Matt</div><div><br></div><div><br></div><div>Matthew Mayernik, Ph.D.</div><div>NCAR Library</div><div>National Center for Atmospheric Research (NCAR)</div><div>University Corporation for Atmospheric Research (UCAR)</div><div>Boulder, CO</div><div><a href="mailto:mayernik@ucar.edu" target="_blank">mayernik@ucar.edu</a><br></div></div>
