Research data

You may also aim to deposit the research data needed to validate the results presented in the deposited scientific publications.

What is research data?

"In the context of these Principles and Guidelines, “research data” are defined as factual records (numerical scores, textual records, images and sounds) used as primary sources for scientific research, and that are commonly accepted in the scientific community as necessary to validate research findings. (UNESCO, OECD Principles and Guidelines for Access to Research Data from Public Funding, 2007)

However, this definition may appear too narrow as it does not consider other types of research data, such as blogs, projects, reports etc.

Where to deposit the research data?

Finding a subject data repository and Databib are registries of research data repositories.


If you have not found any relevant data repository, you may deposit your research data in the Zenodo orphan repository (launched in 2013 by OpenAIRE and CERN).

Linking publications to research data

The OpenAIRE repository (which harvests HAL metadata) should be able to link the deposited publications to related research data through their DOI.

Please note that files may also be uploaded in HAL as "supplementary data", when or after depositing your publication.

Is it mandatory?

Open access to research data is mandatory for projects participating in the Open Research Data Pilot.

For the 2014-2015 Work Programme, several areas of H2020 are participating in the Open Research Data Pilot (See the list in Guidelines on OA to scientific publications & research data in H2020 "5. Open Research Pilot").

Projects may at any stage opt out of the Pilot for a variety of reasons, namely:

  • the project will not generate or collect any research data,
  • participating is incompatible with the obligation to protect results to be commercially or industrially exploited,
  • there are security issues or personal data that needs to be protected.

During the lifetime of a project an opt out remains possible for any of the reasons above and needs to be described in the projects' Data Management Plan (DMP).
