Minimum Information About a Plant Phenotyping Experiment

MIAPPE is an open, community driven project to harmonize data from plant phenotyping experiments. MIAPPE comprises both a conceptual checklist of metadata required to adequately describe a plant phenotyping experiment, and software to validate, store and disseminate MIAPPE-compliant data. We welcome contributions from anyone interested in plant phenotyping data.

Development of MIAPPE is an open process, so if you would like to do more than just comment, and to participate in the ongoing development, please let us know via miappe-feedback@ebi.ac.uk.


Plant phenotyping data is diverse, dispersed and increasingly plentiful owing to the application of new automated techniques. While various initiatives have explored how to describe plant traits (e.g. the Plant Trait Ontology) and phenotypes, description of the experimental design that provides the context for phenotypic observations is not well-standardized. A basic description of the materials used and the experiment performed is needed to support data discovery and data mining applications. MIAPPE – the Minimal Information About a Plant Phenotyping Experiment – is in development to address these needs.

MIAPPE is a Minimum Information (MI) standard for plant phenotyping. It defines a list of attributes that might be necessary to fully describe a phenotyping experiment, following the model originally established for microarray data. Not all of the elements listed in an MI must be reported in each case. An MI document should rather be considered as a checklist, and consulted by a person describing or depositing the data to ensure the inclusion of all important data characteristics, i.e. what is meaningful for the interpretation and potential replication of the research.

MIAPPE is a logical standard - but there are specific implementations of tools designed to support its use and application, for example, in the ISA-tools framework. We are working with the developers of the Plant Breeding API (BRAPI) to ensure the compliance of BRAPI with the MIAPPE standard, and to coordinate future developments.

MIAPPE was originally been developed in the context of the transPLANT, European Plant Phenotyping Network and ELIXIR-EXCELERATE projects, but we are keen to work with anyone interested in contributing to, reviewing or using the standard, or developing new tools.
