C.16:1 - Intent (Normative)

Name. Measurement & Metrics Characterization (MM‑CHR).

Use this when. A reading needs interpretation, or a proposed measurement needs a model. Ask what quantity or Characteristic is sought, how the procedure produces an indication, and what can be inferred from it under the measurement conditions.

What changes in practice. The practitioner constructs or recovers the relation that makes a reading informative about the subject. This can reveal an influence to include, an ambiguity to preserve, or an arrangement to change. When reporting a performed measurement, connect the attributed values and their uncertainty to the method, model, calibration and work that obtained them. A later diagnosis or decision uses that interpreted result.

Not this pattern when. Use A.17 for the Characteristic, A.18 for scale-operation legality, C.16.P while measurement wording is still ambiguous, A.19.CPM for comparison, A.19.SelectorMechanism for selection, C.28 for causal use, A.10/G.6 for provenance, B.3 for assurance, G.4 for an acceptance declaration, G.11 for currentness, and C.11 for a decision result. C.16 supplies none of those results by implication.

Local designators. MeasurementSpecification, MeasurementMethod, MeasurementModel, MeasurementWork, MeasurementResult, and MeasurementResultEpisteme name exact objects in one case; they are not new public U-kinds or universal relation types. MeasurementMethod is one exact U.Method; MeasurementWork is one dated U.Work; MeasurementResultEpisteme is one C.2.1 episteme.

Compatibility with the retained measurement family. U.DHCMethod remains the durable measurement-definition value that fixes the Characteristic, Scale and applicable unit and cites the method and model. A preference rule belongs to the evaluation that uses the result, when one is being made. U.Measure remains the durable reading claim: when persisted, it is the C.2.1 result episteme that states the C.16 measurement result. U.Unit carries quantity-kind and conversion semantics when the Scale requires them. U.EvidenceStub is only a compact locator into A.10/G.6 provenance; it is not the measurement result, an evidence carrier, a work record, or a relation that establishes measurement.
