Biological Collections Ontology
"The Biological Collections Ontology (BCO) is an application ontology developed as part of the Biocode Commons project, within the OBO Foundry framework. The goal of the BCO is to support the interoperability of biodiversity data, including data on museum collections, environmental/metagenomic samples, and ecological surveys. The BCO covers distinctions between individuals, organisms, voucher specimens, lots, samples, the relations between these entities, and the processes governing the creation and use of 'samples'.
