You can create a private link to the data you have archived with data.ncl before it is published openly. This can be useful if you would like to share access to project partners. To create the link upload the data and then click generate private link and save changes rather than publish. Once the data is ready for publication simply go back to the record in the My data view and publish the record.
You can also reserve a digital object identifier (DOI) for the archived data, which is useful for peer reviewed journal publishing process. Rather than publishing the data ahead of the article you can reserve the DOI to create the data access statement for inclusion in the paper and then publish the data once the author accepted manuscript has been submitted.
