Metric

Definition of a quantitative property and its value semantics

Definition

Mechanism

A definition of a quantitative property. It identifies the target property, the rule used to derive its values, and the value schema that makes those values interpretable. Applying the definition produces readings; observed values and their context are recorded separately rather than changing the definition.

Invariants

  1. Quantitative Output: `value_schema` admits only numbers or finite structures whose leaves are numbers, and declares the units, range, or dimensions needed to interpret them.
