| isPrimitive | true |
| naturalLanguageDefinition | An information object that quantifies a quality. |
| primitiveRationale | A precise account of the representation of magnitudes is beyond the scope of IDO. |
| usageNote | Quantification may be on nominal, ordinal, and other scales. |
| This class may be used for data that don't fit the restriction to "single unit, single number" of 'scalar quantity datum', including data employing vectors instead of numbers, and conventional categories like "high" and "medium". | |
| Comment | This class is inspired by the class "measurement datum" of the Information Artifact Ontology (IAO). The change of wording from "measurement" to "quality" is intended to support cases where measurement is not involved, such as with nominal values. |

| Example | 10 volts, high (of pressure), low (of temperature), category 3 (as used to rate the strength 'quality' of a storm), 3 MB (a file size), qualifications, grades. |
| scopeNote | Introduce subclasses of 'quality datum' in RDL to distinguish categories of data, such as nominal versus measured values. |
