The BARD platform aims to enable researchers to effectively use data from the Molecular Libraries Program (MLP) to generate new hypotheses. It provides tools for assay registration, querying and visualization of over 4,000 assays, 35 million compounds and 300 projects. These include intuitive guided queries, cross-assay views, and predictive models. The platform structures data using an Assay Definition Standard to integrate ontologies and represent assay metadata, results and experiments. This supports knowledge discovery and hypothesis generation from diverse chemical biology datasets.
