Zenodo

Last updated: 21 May 2025 at 9:36.

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.

General information

Type of service: Repository
Service homepage: https://zenodo.org/
Provider: CERN

Administrative information

Data curation strategy:
Metrics: Zenodo tracks two types of evens: - Visits to a record page. - Downloads of a file.
Funding source: https://about.zenodo.org/infrastructure/
Intellectual property: By uploading content, no change of ownership is implied and no property rights are transferred to CERN. All uploaded content remains the property of the parties prior to submission.

Target group

Target audience(s): Centre for Science and Technology Studies, Faculty of Archaeology, Faculty of Governance and Global Affairs, Faculty of Humanities, Faculty of Law, Faculty of Science, Faculty of Social and Behavioural Sciences
Stage in research process: After

Costs

Costs: Content may be uploaded free of charge by those without ready access to an organized data centre

Classification of the service

Confidentiality classifications for data: Internal / Restricted, Public

Formats

Accepted metadata formats: All metadata is stored internally in JSON-format according to a defined JSON schema. Metadata is exported in several standard formats such as MARCXML, Dublin Core, and DataCite Metadata Schema (according to the OpenAIRE Guidelines).
Accepted file formats: All files formats
Supported data type(s): Archived data, Audiovisual data, Images, Network-based data, Other, Plain text, Raw data, Scientific and statistical data formats, Source code, Standard office documents, Structured graphics, Structured text

Storage

Maximum size of data: Total files size limit per record is 50GB. Higher quotas can be requested and granted on a case-by-case basis.
Version management: supported
Quality control: supported

Access

Access requirements: Open, closed, restricted - registration, embargoed
Tools/Interfaces for access: Web-interface, API, OAI-PMH
Supported type(s) of persistent identifiers: DOI

Preservation

Long term guarantees: Versions: Data files are versioned. Records are not versioned. The uploaded data is archived as a Submission Information Package. Derivatives of data files are generated, but original content is never modified. Records can be retracted from public view; however, the data files and record are preserved. Replicas: All data files are stored in CERN Data Centres, primarily Geneva, with replicas in Budapest. Data files are kept in multiple replicas in a distributed file system, which is backed up to tape on a nightly basis. Retention period: Items will be retained for the lifetime of the repository. This is currently the lifetime of the host laboratory CERN, which currently has an experimental programme defined for the next 20 years at least. Functional preservation: Zenodo makes no promises of usability and understandability of deposited objects over time. File preservation: Data files and metadata are backed up nightly and replicated into multiple copies in the online system. Fixity and authenticity: All data files are stored along with a MD5 checksum of the file content. Files are regularly checked against their checksums to assure that file content remains constant. Succession plans: In case of closure of the repository, best efforts will be made to integrate all content into suitable alternative institutional and/or subject based repositories.
