Plant Phenotype Experiment Ontology

The Plant Phenotyping Experiment Ontology (PPEO) is an implementation of the Minimal Information About Plant Phenotyping Experiment. It lists and organises all the informations necessary to describe and reuse a phenotyping dataset following FAIR principles (Findable Interoperable Accessible Reusable). It has been initiated with experts from Elixir, Emphasis, Bioversity International - CGIAR and RDA.
