ready Units Ontology

Abbreviation: UO

General Information
The Units Ontology (UO) models metrical units for use in conjunction with PATO. Units are basic scientific tools that render meaning to numerical data. Their standardization and formalization caters for the report, exchange, process, reproducibility and integration of quantitative measurements. The Units Ontology is an ontology currently being used for the standardized description of units of measurements.

Brassica Information Portal
The Brassica Information Portal is a web repository for population and trait scoring information related to the Brassica breeding community. It provides information about quantitative trait loci and links curated Brassica phenotype experimental data with genotype information stored in external data sources. Advanced data submission capabilities and APIs enable users to store and publish their own study results in BIP. The repository can be easily browsed thanks to a set of user-friendly query interfaces.
