A.17:1 - Context

To have reproducibility and explainability there is a need to measure various aspects of systems or knowledge epistemes or publications. A dedicated measurement backbone (see C.MM‑CHR, Measurement & Metrics Characterization) already exists, prescribing the CSLC discipline – i.e. define a Characteristic, choose a Scale (with a Unit if applicable), record a Level/Value, and thus obtain a Coordinate on that scale, optionally mapping to a Score via a ScoringMethod (USCM). However, historically multiple near-synonyms (“axis”, “dimension”, “property”, “feature”, “metric”) have been used interchangeably for “what is being measured,” and often the aspect itself gets conflated with how it is expressed (units, ranges, labels). This pattern enters the FPF Kernel lexicon to canonize a single term for the measured aspect and enforce a clear separation between what is measured and how it is measured.
