One of the outputs of the RDA Wheat Data Interoperability (WDI) working group is a set of guidelines for data sharing along with use cases. The guidelines include phenotyping metadata recommendations like Minimal Information About Plant Phenotyping (MIAPPE) or ontologies for data annotation like the Crop Ontology. The objective of the current project is to implement some of those recommendations for data publication and to share a rich public dataset as RDF in a dedicated SPARQL endpoint. We want also to improve recommendations for this specific use case. The targeted wheat dataset is the public INRA Breeding Network, available in GnpIS (http://dx.doi.org/10.15454/1.4489666216568333E12 ), a platform involved in the Elixir European project. It includes experimentations in six locations over fifteen years
