Post-composition with the extensions field. a Example of OMP terms with pre-composed groupings at the level of resistance to chemicals. b Use of an extension to specify increased resistance to acriflavine hydrochloride using the Relations Ontology term RO:0002503 (towards) to link the ChEBI term CHEBI:74728 (acriflavine hydrochloride) to the OMP term for increased resistance to a chemical. c Other uses of the RO:0002503 (towards) relationship include specifying increased resistance to a beta-lactam (ampicillin), decreased organic carbon source utilization (lactose), and decreased sensitivity to a bacteriophage (bacteriophage Chi)
