We’d like to invite you to celebrate our 10th anniversary with us by sending us a birthday greeting telling us how Zenodo helped you. Your story is what matters! Tweet here

Zenodo was launched 10 years ago on May 8th by CERN and OpenAIRE. The goal since day one has been to enable any researcher from anywhere in the world to participate in practising open science. Today, 10 years later, Zenodo supports more than 300,000 researchers in 7500+ research organisations in 153 countries to do just that. A recent study[1] conservatively estimated the socio-economic impact of Zenodo in society to 95 million EUR per year but more likely close to 1 billion EUR/year. All in support of the mission to provide the platform for all researchers to publicly share their work and join the open science movement.

We always believed that research data should end up where researchers can care best for them, whether that be a subject/institute/national repository, but we also knew that gaps in the offerings still left an enormous quantity of research data with nowhere else to go, that we could usefully offer help to.

Zenodo is now a core enabler of open science practice by providing trusted long-term storage of research, especially to those in most need and without the means. CERN is a leader of Big Data storage, creating technologies at the scale frontier, already keeping almost 1 exabyte of high-energy physics data safe. By housing Zenodo in a corner of the CERN Data Centre, we use this expertise to share what we find easy with others that find it hard.

Thank you

We would also like to send a BIG thank you to all our funders and donors who have sustained our growth and seen the value of our offering.

A special thank you goes to:

  • European Union
  • Alfred P. Sloan Foundation
  • Arcadia Fund
  • US National Institute of Health
  • CERN and OpenAIRE

[1] The Future Circular Collider Innovation Study (funded by the European Union under grant number 951754) studied the socio-economic impact potentials of open data and software for a Future Circular Collider based on an analysis of the LHC. This included an analysis of Zenodo by PhD student Irene Crespo Garrido supervised by Johannes Gutleber (CERN) and María Loureiro García (University de Santiago de Compostela) to be published later in 2023.

Join us for the NIH Virtual GREI Workshop Jan 24 & 25

by Lars Holm Nielsen, on January 9, 2023

We hope you will join us for our next Generalist Repository Ecosystem Initiative (GREI) event, the Virtual GREI workshop on January 24 & 25.

Virtual Generalist Repository Ecosystem Initiative (GREI) Workshop

Tuesday, January 24 11am-4pm ET & Wednesday January 25 11am-3:30pm ET Registration and agenda at: https://datascience.nih.gov/news/grei-workshop-january-24-25-2023

This 2-day virtual workshop is presented by the seven generalist repositories participating in the Generalist Repository Ecosystem Initiative (GREI), sponsored by the NIH Office of Data Science Strategy.

The GREI workshop will focus on GREI's vision of developing collaborative approaches for data management and sharing through inclusion of the generalist repositories in the NIH data ecosystem, and to better enable search and discovery of NIH-funded data in the generalist repositories. The workshop is aimed at researchers of all stages including those funded by NIH and those who support data sharing at academic institutions, funders, publishers, repositories, and beyond.

The workshop will feature keynote speakers and panel discussions with leaders in open data from the research community, NIH, and data community organizations. Interactive training sessions led by GREI repositories will present use-case-specific guidance on sharing and discovering data in generalist repositories. The workshop will also gather community feedback to inform future GREI work to enhance support for NIH data sharing with common functionality, interoperability, and ‚Äúcoopetition‚ÄĚ among generalist repositories.

Zenodo’s next generation platform - InvenioRDM

by Lars Holm Nielsen, on December 7, 2022

We're excited to share our plans for Zenodo in the coming 6-12 months.

TL;DR - See our demo site for Zenodo's next-generation platform based on InvenioRDM.

Next-generation platform

We are currently in the process of moving Zenodo on top of our next-generation platform based on InvenioRDM. InvenioRDM is a digital repository platform born out of Zenodo and developed together with 25 other partners.

For institutions/domains, InvenioRDM enables them to provide the "Zenodo-experience" in their own repositories. For Zenodo, InvenioRDM enables us to collaborate with partners on the technical platform underpinning Zenodo.

InvenioRDM is already being used in production system today, see for instance:

The ZenodoRDM project

The move to InvenioRDM is being managed and coordinated through our ZenodoRDM project. The focus of the project is to migrate Zenodo.org with the existing feature set to InvenioRDM and provide backward compatibility to our users.

The largest challenge in the project is by far the full data migration process. Zenodo today has almost 3 million records, 300k users and many API integrations, and thus we're doing our outmost to minimize disruptions during the data migration process and ensure existing API integrations will continue to work unaffected.


Our project is designed to start early on with the data migration, and continue it as a main activity throughout the entire project. Thus, a large fraction of each milestone is dedicated to data migration.

In addition for each milestone, we'll work with specific users to validate that everything works as supposed.

The milestones for the project

  • MS2 Themed demo-site with initial data migration
  • MS3 Legacy API support
  • MS4 Basic feature set completion
  • MS5 Normal feature set completion
  • MS6 Advanced feature set completion
  • MS7 Support operations
  • MS8 Launch


We are expecting to go-live with the new platform in Autumn 2023.

What's new

The move to InvenioRDM will also provide some long awaited new features for Zenodo. See below what's coming, or even better, check out the new features for yourself on our demo site.

State of demo site

We have loaded a partial dump of 1M records and a couple of communities from Zenodo into the demo site. The records are not connected with user accounts and thus cannot be edited. You can create new communities and test the new upload form and get a feeling for some of the changes we've made.

Community members

InvenioRDM supports having members with different roles - that means multiple users can curate records and/or see closed access content in the communtiy. Zenodo will come with the following community roles:

  • Reader: A reader is a member of the community and can view restricted files owned by the community.
  • Curator: A curator can in addition to a reader also edit/accept/decline records in a community.
  • Manager: A manager can in addition to curators also manage members of a community.
  • Owner: An owner has full administrative access to a community, and can change all settings as well as delete the community.

More about communities


Submission to communities now enable the curator and uploader to have a conversation directly on the platform. Curators of the community will receive the review request, and can have a conversation with the submitter, as well as preview the submitted record. Both the submitter and curator can edit and update the record under review until it's published:

More about review

Upload form

Our upload form have also gotten a larger overhaul. You'll for instance find the following changes:


Will your APIs be backward compatibile?

Yes, we do our outmost to ensure backward compatibility of our APIs, and your integration will continue to work on the new platform as well.

Will I be required to update my API integration ?

After Zenodo on InvenioRDM has been launched (Autumn 2023), we will deprecate some of our existing APIs. We will provide a migration period of 1-year for the transition. New features, will only be available on the new API.

Where do I find documentation of your new REST API?

You can find the documentation for our new REST API in the InvenioRDM documentation.

Will the community curators be able to edit my existing records?

No. You will have to opt-in to allow community curators to edit the metadata of records already uploaded on Zenodo. Metadata of new recods you upload after the launch will by default be editable by curators (and you'll be asked to confirm).

Will feature X still work?

Yes, we will provide backward compatiblity for all existing features.
