Frequently Asked Questions

General

Can I change the file in the already published record?

Once the record has been published, you can no longer change the files. Exceptionally, we allow small modifications to a record's files, if and only if the record was published recently (less than a month). If you have spotted mistakes such as typos, accidental omission of important files/inclusion of hidden files or confidential files and would like to update them, please contact us and include the following information:

  • Send us the email from the address your are registered with in Zenodo.
  • Direct link to the record you would like to update (e.g. DOI or URL).
  • Mention any use of the DOI in e.g. papers or social media.
  • Include the new files as email attachment or provide the public URL to files if they are too big for email.
  • Provide a reason for update.

Meeting above points ensures that we can resolve your case faster. Please note that we may reject your request if we deem that it is not a small change.

Why is my closed access upload not on the front-page?

Zenodo is a strong supporter of open data in all its forms (meaning data that anyone is free to use, reuse, and redistribute) and takes an incentives approach to encourage depositing under an open license. We therefore only display Open Access uploads on the front-page. Your Closed Access upload is still discoverable through search queries, its DOI, and any communities where it is included.

Why do you allow closed access uploads?

Since there isn't a unique way of licensing openly and nor a consensus on the practice of adding attribution restrictions, we accept data under a variety of licenses in order to be inclusive. We will, however, take an active lead in signaling the extra benefits of the most open licenses, in terms of visibility and credit, and offer additional services and upload quotas on such data to encourage using them. This follows naturally from the publications policy of the OpenAIRE initiative, which has been supporting Open Access throughout, but since it aims to gather all European Commission/European Research Area research results, it allows submission of material that is not yet Open Access.

What happened to the OpenAIRE Orphan Record Repository?

OpenAIRE Orphan Record Repository got a make-over and was re-branded as Zenodo. If you deposited your article in OpenAIRE Orphan Record Repository, it is also available in Zenodo. However, your user account was not transferred to Zenodo, so you will have to register again. If you register with the same email address in Zenodo as you used in OpenAIRE Orphan Record Repository, you will still have access to your publications. Don't hesitate to contact us for further information.

Where does the name come from?

Zenodo is derived from Zenodotus, the first librarian of the Ancient Library of Alexandria and father of the first recorded use of metadata, a landmark in library history.

How much digital storage-space does CERN have available?

Zenodo is currently a drop in the ocean. CERN stores more than 100PB (petabytes) of physics data from the Large Hadron Collider (LHC), and produces roughly 25PB per year when the LHC is running.

Technical

How can I edit the metadata of a published record?

On the record page and click the orange Edit button in the top-right corner. You will be taken to a form similar to the upload form, where you will be able to edit almost all of the record's metadata. Once you are done modifying it, click "Save" and then "Publish".

Policies

What are the size limits in Zenodo?

We currently accept up to 50GB per dataset (you can have multiple datasets); there is no size limit on communities. However, we don't want to turn away larger use cases. If you would like to upload larger files, please contact us, and we will do our best to help you. Please be aware that we cannot offer infinite space for free, so donations towards sustainability are encouraged.

What can I upload?

All research outputs from all fields of science are welcome. In the upload form you can choose between types of files: publications (book, book section, conference paper, journal article, patent, preprint, report, thesis, technical note, working paper, etc.), posters, presentations, datasets, images (figures, plots, drawings, diagrams, photos), software, videos/audio and interactive materials such as lessons. Please see further information in our Terms of Use and Policies.

Is Zenodo only for EU-funded research?

No. We are open to all research outputs from all fields of science regardless of funding source. Given that Zenodo was launched within an EU funded project, the knowledge bases were first filled with EU grants codes, but we are extending this to other funders.

Is my data safe with you / What will happen to my uploads in the unlikely event that Zenodo has to close?

Yes, your data is stored in CERN Data Center. Both data files and metadata are kept in multiple online and independent replicas. CERN has considerable knowledge and experience in building and operating large scale digital repositories and a commitment to maintain this data centre to collect and store 100s of PBs of LHC data as it grows over the next 20 years. In the highly unlikely event that Zenodo will have to close operations, we guarantee that we will migrate all content to other suitable repositories, and since all uploads have DOIs, all citations and links to Zenodo resources (such as your data) will not be affected.

GitHub

My organizational repository does not show up on the GitHub list.

In order to see and archive your organizational repositories on Zenodo you will need to have "Admin" permissions on said repository, either as an Admin of the organization or an Admin of one of your organization's repositories. Additionally, please make sure that the OAuth application on GitHub is granting permissions not only to your personal repositories but also to your organizational ones - to verify that go to your GitHub OAuth settings in your profile (https://github.com/settings/applications), and click on the Zenodo application to see more details. Make sure that Zenodo is given access (green tick) to your organization under "Organization access".

After that, navigate to your Zenodo GitHub settings page: https://zenodo.org/account/settings/github/ and click the "Sync now" button at the top.

I made a GitHub release, but it does not show up on Zenodo.

Make sure the repository was enabled before the release was made, otherwise feel free to contact us.

Is it possible to archive a GitHub repository, before it was enabled on Zenodo?

Only the repositories which were enabled before a release was made will be archived automatically. If you want to archive some of your old releases, you can always download a release ZIP from GitHub and upload it to Zenodo using our web interface as a regular upload.
