Data Terra Repository

Data resulting from publicly funded research must be as open as possible, and as closed as necessary. EU recommendation on access to and preservation of scientific information

The Data Terra research infrastructure’s data repository is predicated on an open science approach in line with FAIR principles, which set out how research data should be organized to make them Findable, Accessible, Interoperable and Reusable.

Initiated in 2018 by the Ministry for Higher Education, Research and Innovation, the national open science plan aims to structure actions that seek to encourage open access and sharing of data, publications and source code. This plan mandates dissemination to the widest number of data from government-funded projects. A national federated research data platform is set to come on stream during the course of 2022. This platform will include a national repository to accommodate research data for which no thematic or institutional solution exists, and a catalogue to raise the profile of existing repositories of trust in the national arena.

With this aim in mind, the Data Terra Repository is set to become the national storehouse for Earth system and environment data. These data will be consultable through the national platform’s catalogue.

Data Terra Repository

The Data Terra Repository offers the Earth system and environment scientific communities a service they can trust tailored to the specific features of georeferenced data. Project research data and long-tail data can be deposited, in line with FAIR principles and with a DOI for each dataset. A team of subject matter contacts supports and advises users throughout the process.

This data repository is underpinned by all of the partners of Data Terra and its data hubs (CNRS, CNES, IRD, INRAE, Meteo-France, Ifremer, IGN, BRGM, etc.). A dedicated team of experts from the French geological survey BRGM and Data Terra is coordinating its implementation. The repository is hosted at BRGM.


The maximum authorized volume is 5 Gb per data file and 100 Gb for the total deposit. Specific solutions exist for larger data volumes after discussion with the expert contacts. Metadata follow domain standards and directives (ISO 19115-3, INSPIRE) and are compatible with and exportable to other formats/schemes (GeoDCAT-AP, DataCite, etc.). They are also accessible in different formats—JSON, XML, RDF—via standardized APIs.

A landing page is tied to each dataset deposited in the repository. The associated DOI and a citation are included on this web page.

All data deposited in the repository are by default freely accessible. The depositor may impose an embargo for a maximum of two years. The metadata remain available. The default user licence is Creative Commons CC-BY 4.0, although other licences may be used (Etalab or other CC licences). It is strongly recommended to choose a non-proprietary format when depositing data in the Data Terra Repository. The list of recommended formats can be consulted on the CINES website.

The repository enables data deposited to be linked to external resources, such as the researcher’s profile (e.g. ORCID), publications (e.g. published in HAL), source code (e.g. archived in Software Heritage) and associated projects (e.g. H2020, Horizon Europe, ANR, etc.).

The data repository can be harvested via standardized protocols (OAI-PMH, CSW, OpenSearch). Metadata in the repository will be consultable in Data Terra’s data and services catalogues and in the national federated research platform’s catalogue.

Data Terra Repository has a search interface that lets you consult, access and re-use (according to access restrictions) all data published there.

Publishing data in the repository

User guides will be available shortly to help you deposit data.

Legal liability

Data Terra Repository disseminates data within its remit as is. Data Terra will carry out technical checks on data deposits but is in no way liable for their scientific quality. The depositor is responsible for the content of data deposited and for compliance with regulations (GDPR, sensitive data, authors’ consent, etc.). Data Terra reserves the right to reject any deposit deemed not within the repository’s remit of Earth system and environment science data.

Data made available through this repository are protected by copyright. Users must comply with the terms of the licence they have chosen and its restrictions. Data Terra does not warrant the accuracy or exhaustiveness of information on its website.
