The objectives of the INRA plant BRCs are to gather, conserve, characterize and provide high quality plant materials to their collaborators and users, mainly researchers and breeders. For that purpose, they are ensuring a high degree of quality in their management systems and give access to their catalogs through an information system organized in two layers, (i) local information systems that allows the BRCs to manage their collection and (ii) a central system, the INRA Plant Genetic Resource Information System (GnpIS-Siregal https://urgi.versailles.inra.fr/siregal), integrated with the GnpIS information system of the URGI platform (ISO 9001). GnpIS allows linking information on plant genetic resources with genetic, genomic or phenotypic data. In the last six years, INRA has focused its efforts on the development and implementation in GnpIS of strategies and tools aiming at facilitating the access to data and at making them interoperable and re-usable. This was achieved through several international projects (e.g. FP7 TransPLANT, ARCAD FEDER, H2020 ELIXIR Excelerate) or initiatives (Wheat Initiative, Research Data Alliance, Breeding API) contributing to the development (i) of community recommendations for data standardisation (e.g. wheatis.org), (ii) of a data standard for phenotyping experiment (www.miappe.org), (iii) of several crop specific ontologies in the frame of the CropOntology (http://www.cropontology.org/), (iv) of portals giving access to data in distributed information systems and (v) of a standard Application Programming Interface for plant genetics and breeding that will facilitate the development of such portals. In addition, an effort has recently been made in curating and diffusing the data: the assignment of Digital Object Identifier (DOI) to accessions and to data sets allows to identify them more easily. Moreover, the French national collections hosted by INRA are now integrated in both Eurisco and GBIF international biodiversity portals in order to improve their accessibility.
