Data publication workflow. To ensure a trusted release of research data, a review process has been designed. The first step for a data-publication request is the generation of a “landing page” for the applied citable identifier. The underlying URL is served by the embedded HTTP server. If a dataset has a release date in the future, the page locks the data download. If the user requested a DOI from DataCite, the system generates a unique DOI and migrates the metadata to DataCite-XML format. After the reviewer approves the publication, the DOI request is sent to the DataCite REST web service. Finally, the user gets an email notification with the accepted DOI or URL.
