Zenodo is a general-purpose open repository developed under the European OpenAIRE program and operated by CERN.[1][2][3] It allows researchers to deposit research papers, data sets, research software, reports, and any other research related digital artefacts. For each submission, a persistent digital object identifier (DOI) is minted, which makes the stored items easily citeable.[4]
Zenodo was launched on 8 May 2013, as the successor of the OpenAIRE Orphan Records Repository[5] to let researchers in any subject area comply with any open science deposit requirement absent an institutional repository.
It was relaunched as Zenodo in 2015 to provide a place for researchers to deposit datasets;[6] it allows the uploading of files up to 50 GB.[7][8]
It provides a DOI to datasets [9] and other submitted data that lacks one to make the work easier to cite and supports various data and license types. One supported source is GitHub repositories.[10]
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.[11]
Zenodo is run with Invenio (afree software framework for large-scale digital repositories), wrapped by a small extra layer of code that is also called Zenodo.[12]
In 2019, Zenodo announced a partnership with the 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.[13]
As of 2021, Zenodo's publicly available statistics[14] for open items reported a total of over 45 million "unique views" and over 55 million "unique downloads".[15]
Also in 2021, Zenodo reported it had crossed 1 Petabyte in hosted data and 15 million yearly visits.[16]
