QualityDatum
A class with identifier http://rds.posccaesar.org/ontology/lis14/rdl/QualityDatum
| Source ontology | Industrial Data Ontology |
| is primitive | true |
| natural language definition | An information object that quantifies a quality. |
| primitive rationale | A precise account of the notion of representation of magnitudes is beyond scope of IDO. |
| usage note | 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. |
| scope note | Introduce subclasses of 'quality datum' in RDL to distinguish categories of data, such as nominal versus measured values. |
