Zenodo is a general-purpose open-access repository developed under the European OpenAIRE program and operated by CERN.[1][2] It allows researchers to deposit data sets, research software, reports, and any other research related digital artifacts. For each submission, a persistent digital object identifier (DOI) is minted, which makes the stored items easily citeable.


Zenodo was created in 2013 under the name OpenAire orphan records repository,[3] to let researchers in any subject area to comply with any open science deposit requirement absent an institutional repository. It was re-launched as Zenodo in 2015 to provide a place for researchers to deposit datasets[4] and allows upload files up to 50 GB.[5][6]

It provides a DOI to datasets[7] and other submitted data which lacks one, to make the work easier to cite and supports various data and license types. One supported source are GitHub repositories.[8]

Zenodo is supported by CERN "as a marginal activity", and hosted on the high-performance computing infrastructure that is primarily operated for the needs of high-energy physics.[9]

Zenodo is run with Invenio (an open source software framework for large-scale digital repositories), wrapped by a small extra layer of code that is also called Zenodo.[10]

In 2019 Zenodo announced a partnership with fellow data-repository Dryad to co-develop new solutions focused on supporting researcher and publisher workflows as well as best practices in software and data curation[11].
