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.

ChEMBL is an open, manually-curated, large-scale bioactivity database containing information from medicinal chemistry literature. It brings together chemical, bioactivity and genomic data to aid the translation of genomic information into effective new drugs. Information regarding the compounds tested (including their structures), the biological or physicochemical assays performed on these and the targets of these assays are recorded in a structured form, allowing users to address a broad range of drug discovery questions.

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.

MetaSRA is a database of normalized SRA human sample-specific metadata following a schema inspired by the metadata organization of the ENCODE project. This schema involves mapping samples to terms in biomedical ontologies, labeling each sample with a sample-type category, and extracting real-valued properties.
