Open science: IEMN researchers open up their datasets

Publishing raw or reprocessed research data on an institutional data warehouse offers many advantages: data traceability, contribution to the scientific community, compliance with institutional requirements, transparency to society. Several IEMN researchers have already taken the plunge, thanks in particular to the opening of the IEMN sur l’entrepôt national Recherche Data Gouv

Data: “open as much as possible, close as much as necessary”

What do the IEMN’s supervising institutions have to say? A brief overview…

CNRS : In 2020, CNRS rolled out a “Données de la recherche“ plan to support its community in making data accessible and reusable. In an interview, Alain Schuhl, CNRS Director General for Science, explains why it’s important to open up research data.

Alain Schuhl :
« Making available the data attached to a scientific publication is essential for understanding, reproducing and validating a scientific result. Sharing these data also enables other teams to reuse them without having to generate them again, which saves time and ensures better use of research funds. Above all, new knowledge can emerge from the cross-fertilization of data from very different communities, provided it is disseminated with a high level of quality and contextualization. It is therefore important to make data “FAIR” – easy to find, accessible, interoperable and reusable – right from the design stage of research projects. »
« In some cases, a genuine change of culture is required. This means changing practices and attitudes, as well as developing tools for the management, sharing, long-term preservation and dissemination of research data. »

Université de Lille : Opening up science to society, and giving everyone free access to research publications and data: this is the project of the University of Lille, a pioneer in this field, which is detailed in its feuille de route en 2021.

“The LORD (Lille Open Research data) project offers a comprehensive package of assistance and support for research teams in the Lille area, covering all aspects of data management. It comprises a number of actions designed to meet the needs of research teams: awareness-raising and training initiatives, individualized support for teams at all stages of the data lifecycle, as well as for codes and software. The aim is to take as much of the burden off research teams as possible.”
“Researchers can find all their contacts thanks to the one-stop shop. What’s more, the IEMN has its own data correspondent within the unit. Combining knowledge of the unit, disciplinary issues and data culture, the latter plays a central role in providing support tailored to the unit’s context.”


UPHF : In 2023, UPHF set up a data steering committee and a règlement sur la gestion des données de la recherche à l’UPHF was enacted. It sets out guidelines for managing and sharing data within the institution. The regulation sets out the best practices that UPHF recommends for the entire research process:

“At a minimum, that data related to publications be shared with the scientific community in the interests of transparency and evidence in support of the results presented and in compliance with the principles of scientific integrity.”

A research production in its own right: IEMN on the institutional warehouse ⇒ Recherche.Data.Gouv

Romain Peretti, Fabrizio Cleri and, more recently, Stéphane Lenfant have used the RDG institutional warehouse to open up their datasets, taking advantage of the launch of the collection IEMN. This collection can be fed directly or mirrored by the CNRS, Université de Lille and Université Polytechnique Hauts de France. In addition to meeting the requirements of our respective funding bodies (Région Hauts de France, ANR, Europe, etc.), the RDG data warehouse provides a structuring framework and real metadata quality, thus ensuring increased visibility. These dataset publications are a real research production in their own right. Let’s hope that the experience of our “early testers” will enable these best practices to be rapidly disseminated within the unit’s research groups. The IEMN intends to continue along this path of more open, collaborative and sustainable science, while respecting the legitimate exceptions provided for by law, which may arise in the context of restricted zones.
