This document summarizes work done on developing an ontology for bean traits and curating associated phenotypic and genotypic data from bean trials. It describes how 140 bean traits were initially defined, ranked based on usage, and then refined into 70 "primary" traits for standardized documentation. Work is ongoing to fully define all traits in the ontology, translate trait descriptions into multiple languages, and standardize variable names and units in phenotypic datasets from bean trials before uploading the curated data to databases by certain target dates. Genotypic datasets will also be uploaded after curation is completed.
