Data associated with scientific pubblications

The European Commission recognizes that research data are as important as the publications they support. Since 2017 all the research data needed to validate the results presented in the deposited scientific publications, known as "underlying data", and any other data should be opened by default

This does not mean opening up all data but instead following the principle of “as open as possible, as closed as necessary” and generally encouraging good data management as part of best research practice.

Opting-out is possible but it must be motivated.

Why Open Data?

• Create new research by encouraging collaboration between different disciplinary fields

• Avoid dispersion and duplication of efforts

• To have an amount of data available that no researcher could collect alone

• Discover data and results that were initially not expected by researchers

• To be able to reproduce and verify the results of previous researches

• Accelerate innovation and competitiveness

• Share research data to promote development in disadvantaged countries

• Avoid the loss of data produced by research and experimentation

 What to deposit?

• data resulting from observations or originated from simulations

• experimental data

• laboratory notes

• slide

• program files

• questionnaires, interviews and answers to tests

• models, algorithms, software programs, video, audio, images, standards, protocols


Data should be deposited using open licenses (see Creative Commons CC 0 or CC by) as required under Horizon 2020.

 Opting out

The European Community provides some cases to opt out when it is not possible to make the data public:

• commercial or industrial exploitation of research results (patents)

• problems related to the confidentiality / security of the project

• protection of personal data or sensitive data

• other legitimate reasons


Where to deposit the research data

The research data must be deposited in open access archives such as Zenodo, born from the collaboration between CERN and the OpenAIRE project.

Currently, most university repositories are not equipped to host the data associated with scientific publications.

The research data repository register, Re3data,, is a very precious tool that offers the possibility to find the most appropriate archive to deposit data according to your disciplinary field
