Experimental Research Ontology (ERO)

The Experimental Research Ontology (ERO) is a small ontology that models some fundamental aspects of data creation in experimental research. ERO is aligned with several upper ontologies, including BFO, IAO, OBI, and SOSA. ERO enables the characterization of different types of experiments by specifying different methodologies and collections of parameters. Methodology specifications may include, e.g., research objectives, experiment setups and procedures, success criteria, or saftey regulations.
