Embargoes make file content inaccessible after a dataset version is published - until the embargo end date. This means that file previews and the ability to download files will be blocked.
To set am embargo:
Setting an embargo on files and publishing the dataset in Dataverse publicizes the persistent identifier (e.g. DOI) for the dataset and makes the metadata, and any the content of un-embargoed files immediately available, but automatically denies access to any embargoed files until the specified embargoes expire.
Users cannot change an embargo, on their own, once a dataset version is published. Please contact email@example.com to correct mistakes or end an embargo early.
