Zenodo is a general-purpose data repository built on open source software that accepts all forms of research output from data files to presentation files. It was developed by the European Organization for Nuclear Research (CERN), but is open to researchers from outside the EU. Data is stored in the CERN Data Center, which provides long-term preservation.

User Access Controls
Option to Share: Users can choose to deposit files under open, embargoed, restricted, or closed access. For embargoed files, the user can choose the length of the embargo period, and the content will become publicly available automatically at the end of the embargo period. Users may also deposit restricted files and grant access to specific individuals.
