Allowed data types | All formats are allowed - even preservation unfriendly. | All. SPSS-filer format are, though, changed from SAW/POR to TAB. |
|
Research restrictions | Anyone is allowed | Researchers from KU are allowed |
|
| Research phase | Any status is accepted, from any phase of the research lifecycle, but the publish/sharing phase has the most focus. Secondary focus is on the preservation phase | ||
Research topic requirement | All topics are accepted There is, though, the file size limit requirement that may be a problem |
| |
Access to data | Both open, closed and embargoed data are allowed. Embargoed data are closed data till a user specified date. Files deposited under closed access are protected against unauthorized access at all levels Zenodo does not track, collect or retain personal information Users may deposit restricted files with the ability to share access with others if certain requirements are met. | Open pr. default.

Withdrawal of data | If the uploaded research object must later be withdrawn, the reason for the withdrawal will be indicated on a tombstone page, which will henceforth be served in its place. Withdrawal is considered an exceptional action, which normally should be requested and fully justified by the original uploader.
