FAIR Data Sharing & Open Research Data Support for FBM UNIL-CHUV Researchers

1. Criteria for Repository Selection
Prioritize Domain-Specific or Data Type-Specific Repositories
Before considering a generalist repository like Zenodo, first check if a data type-specific or domain-specific repository is available. These specialized platforms often provide better visibility and functionality tailored to your field.
For example:
- If you work with large imaging datasets, consider repositories such as BioImage Archive (BIA).
- If your research is in neuroscience, a specialized repository such as E-BRAINS in that domain may offer greater visibility and discoverability than a generalist platform.
Your repository must meet the following criteria:
- Free of Charge, Regardless of Dataset Size → freely accessible repository with no cost for submission or access.
- Tailored Infrastructure for the interested data type → Optimized to host raw and processed data type, with tools for visualizing, downloading, or querying complex datasets.
- Integrated with resources to enhance data accessibility and utility.
- Reliable Long-Term Preservation → the repository Follows robust policies including infrastructure continuity, regular backups, and lifecycle data managementTo support this decision, we provide FAIRshare Explorer, a tool listing recommended repositories by data type and research discipline. Please consult it before choosing where to deposit your data.
- FAIR-Compliant by Design → insures that sample metadata are Findable, Accessible, Interoperable, and Reusable, following community metadata standards and supporting compliance with institutional and funder Open Science mandates (e.g., SNSF, Horizon Europe).
- Flexible Licensing → Ideally supports open licensing options such as Creative Commons CC BY 4.0 or CC0, enabling broad data reuse while ensuring proper attribution.
- European/National Hosting → Ensures compliance with data protection and Open Science standards and policies. https://www.ebi.ac.uk/long-term-data-preservation/
To support this decision, we provide FAIRshare Explorer, a tool listing recommended repositories by data type and research discipline. Please consult it before choosing where to deposit your data.
Mandatory Local Archiving
All data supporting a publication (raw, processed, and analytical) must also be archived on long-term storage provided by DCSR-UNIL or DSI-CHUV (link).

3. Publishing Your Dataset to Data Type-Specific or Discipline-Specific Repositories
Scope: Designed for specific or disciplinary data types, such as:
- Genomic data (ENA: nucleotide sequence data, EGA: human data that requires controlled access).
- RNA sequencing.
- Electron microscopy (EMPIAR: raw image data).
- FACS data (FlowRepository: database of flow cytometry experiments)
- Light microscopy (BioImage Archive: bioimaging data).
- Open research infrastructure that gathers data, tools and computing facilities for brain-related research (EBRAINS)
Use Recommended Standards for File Formats and Metadata Schemas
To ensure interoperability, discoverability, and long-term reuse, always follow the file formats and metadata schemas endorsed by your chosen repository. These community-driven standards are tailored to each data type and archive—and you can discover them quickly with the FAIRShare Explorer @DSBU tool:
- Accepted File Formats → e.g., OME-TIFF, NIfTI, FASTQ, etc.
- Metadata Standards → e.g., REMBI, MIAME, MIAPE, CDISC, etc.
Use FAIRShare Explorer to:
- Identify the exact formats and schemas required by each repository.
- Read the repository descriptions—including data types supported, submission workflows, licensing rules, and access conditions.
- Access step-by-step deposit instructions and examples for every repository.
4. FBM UNIL–CHUV Zenodo Community if no suitable specialized repository exists
If no suitable specialized repository exists, the FBM Dean’s Office strongly recommends depositing your dataset in the following generalist repository:
Depositing in this community allows you to:
- Receive metadata curation and guidance from the Data Stewardship Biomed Unit (DSBU)
- Increase your dataset’s visibility within and beyond FBM
- Ensure traceability of data produced by the faculty
- Link your dataset to your publication, making it easier to cite and access
We recommend submitting your dataset early, ideally during the manuscript review process, so that it can be referenced and properly cited in your article.
Zenodo FBM/CHUV Community Submission Process – Key Information
- You can only submit drafts (unpublished records) to a Zenodo community.
- Both you and the community curators (DSBU) can edit metadata and files during the review phase.
- Your record can be automatically published once approved by the community curators.
Submit your record for review in 3 simple steps:
- Find the community: Search for “FBM UNIL–CHUV” on Zenodo and go to the community page.
- Submit for review: Upload your dataset and request inclusion.
- Manage your submission: Monitor review status and edit if needed.
File Formats and Metadata Recommended Standards for Zenodo
To ensure interoperability, discoverability, and long-term reuse, it is essential to follow the file formats and metadata schemas recommended by the repository itself.

5. Use Horus Dataset Catalog for Sensitive Non Anonymized Data at CHUV
Managing sensitive biomedical data requires strict adherence to privacy and confidentiality standards. Open access to such data is contingent upon explicit consent and the anonymization of personal information.
For sensitive datasets that cannot be anonymized, researchers should utilize the HORUS Dataset Catalog at CHUV, developed and managed by the Data Science Group – DSI
Key features of this catalog include:
- Metadata Highlighting: Provides detailed metadata descriptions of sensitive clinical datasets generated at CHUV.
- Controlled Access: Ensures secure access to sensitive datasets in compliance with legal restrictions.
- High visibility and compliance to FAIR international standard: Enables interoperability between the CHUV catalog and external repository Zenodo, automatically transmitting FAIR metadata for public visibility in the FBM UNIL-CHUV Zenodo community.
Submit your Dataset
The DSBU offers end-to-end assistance with depositing sensitive data via the HORUS CHUV catalog:
Process Overview
- Dataset Submission & Metadata Entry: Researchers are supported by the DSBU to upload their dataset into the HORUS Dataset Catalog and fill in all necessary metadata fields describing the dataset.
- Metadata Review & Curation: A data steward (curator) from the DSBU carefully reviews the submission to ensure the metadata is complete, accurate, and compliant with FAIR principles.
- Metadata Publication to Zenodo: Once validated, the metadata is automatically published to the Zenodo FBM UNIL-CHUV Community, making the dataset discoverable on an international level, even though the data itself remains protected on CHUV internal servers.
- Data Access Request by contacting the PI: When other researchers read a publication referring to a dataset hosted in HORUS, or when they browse Zenodo and find the associated metadata, they gain a detailed understanding of the dataset’s content. If they are interested in using the data, they can contact the Principal Investigator (PI) through its e-mail address listed in the metadata.
- Access Evaluation & Agreement: The PI, possibly with a designated review committee, evaluates whether the data access request is legitimate. Criteria include:
- The resquester comply to the Data Sharing Requests and Procedures
- The requester works in a relevant field,
- Their study is clearly aligned with the dataset’s subject and goals,
- A clear scientific justification for the data reuse is provided.
- Collaboration & Data Transfer and Use Agreement (DTUA):
- If the PI and committee approve the request, a collaboration agreement can be established.
- Data can then be shared with the external team under the terms of a CHUV DTUA (The template used for this agreement is based on the one published by SPHN).
