When you publish data in a data repository you generally get a DOI (or other type of persistent link) that can be used for linking to and citing the dataset. If you use the Swedish National Data Service (SND) for publishing data we can reserve a DOI for you to include in your manuscript while preparing data and documentation for publishing. The DOI will not be activated until the data is ready to be made available and, if you choose, until the journal article has been published. In the meantime, if required, you can allow the journal/reviewers to see a preview of the data publication.
