is a Ontology.
The BioAssay Ontology (BAO) is a formal OWL-DL ontology that establishes common reference metadata terms and definitions for describing low- and high-throughput drug and probe screening assays and their results. It captures assay design, screening formats, detection technologies, perturbagens, biological targets, endpoints, and measured results, enabling integration, aggregation, retrieval, and analysis of bioassay data across resources such as PubChem and ChEMBL. BAO is modularized into reusable components covering biology, properties, and controlled vocabularies.

The BioAssay Ontology (BAO) is a formal OWL-DL ontology that establishes common reference metadata terms and definitions for describing low- and high-throughput drug and probe screening assays and their results. It captures assay design, screening formats, detection technologies, perturbagens, biological targets, endpoints, and measured results.
BAO enables effective integration, aggregation, retrieval, and analysis of bioassay data across resources such as PubChem and ChEMBL. The ontology is modularized into reusable components covering biology, properties, and controlled vocabularies, and is distributed as a complete OWL file alongside its individual modules.
