MIAPPE-HTP v1.0

The miappe-htp profile is a high-throughput-phenotyping variant of MIAPPE. It keeps the MIAPPE investigation/study backbone but expands the model to 28 entities that capture observation levels, spatial layout, growth facilities and the trait/method/scale decomposition of observed variables. Most entities are keyed by name (a few — Observation, FactorValue, ExperimentalDesign, SpatialDistribution — use other identifying fields). The root entity is Investigation.
