Embargo is a period during which a published dataset remains unavailable to others. In the final phase of creating a publication in PURR before submitting publication's draft, researchers are asked to enter a publication date. The default is set to 'immediate'. This means that the publication will became available immediately upon approval of the repository administrator.
PURR believes that immediate access to research findings provides the greatest benefit to researchers. However, publishing conventions differ from discipline to discipline and sometimes researchers prefer to delay publication of their data, e.g. until a journal article is published. By entering a publication date, researchers determine when an embargo expires and dataset will become public. While the data themselves remain private and no unauthorised person can access them, the metadata are discoverable on the DataCite server. The metadata are a requirement for minting a DOI for a dataset.
