The Reagent Ontology (ReO) adheres to OBO Foundry principles (obofoundry.org) to model the domain of biomedical research reagents, considered broadly to include materials applied “chemically” in scientific techniques to facilitate generation of data and research materials. ReO is a modular ontology that re-uses existing ontologies to facilitate cross-domain interoperability. It consists of reagents and their properties, linking diverse biological and experimental entities to which they are related. ReO supports community use cases by providing a flexible, extensible, and deeply integrated framework that can be adapted and extended with more specific modeling to meet application needs.
From James O.: It was an ontology for "reagents" developed by @Matthew Brush. Since OBI was interested in reagents, Matt developed it in coordination with OBI and had plans to submit it to OBO. I believe that REO was once included in Ontobee, and OBI even started using some REO terms. But REO was never submitted to OBO. I believe it was abandoned.
