ZENODO builds and operates a simple and innovative service that enables researchers, scientists, EU projects and institutions to share and showcase multidisciplinary research results (data and publications) that are not part of the existing institutional or subject-based repositories of the research communities. ZENODO enables researchers, scientists, EU projects and institutions to: easily share the long tail of small research results in a wide variety of formats including text, spreadsheets, audio, video, and images across all fields of science. display their research results and get credited by making the research results citable and integrate them into existing reporting lines to funding agencies like the European Commission. easily access and reuse shared research results.

Classification of the service
The data is stored safely for the future using CERN's battle-tested repository software INVENIO used by some of the world's largest repositories such as INSPIRE HEP and CERN Document Server. The technology offered by the software covers all aspects of digital library management from document ingestion through classification, indexing, and curation to dissemination.
Zenodo allows for uploading under a multitude of different licenses and access levels.
Accepted metadata formats
the software uses the MARC21 format by default.
Accepted content types
Audiovisual data; Imagesl; Plain text; Scientific and statistical data; Standard office documents; Images
Accepted preferred formats
Accepteerde file formats
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), posters, presentations, images (figures, plots, drawings, diagrams, photos) and videos/audio.
Maximum size of deposits
Files up to 2GB
Quality control is performed by communities; All uploads also go through a quick spam check by Zenodo staff
Publicly available; closed access uploads are possible
Tools / Interfaces for access
Public registry of all uploaded data sets ; API based on OAI-PMH
Long term guarantees
Complies with international standards for trusted repositories
Developed within OpenAIRE, and, as such, endorsed by the European Union
Zenodo is free for the long tail of Science. In order to offer services to the more resource hungry research, we will introduce a ceiling to the free slice and offer paid for slices above, according to the business model developed within the sustainability plan.
