Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
MoistureMeasurementFunction ⊑ DesignedFunction
Realized in
MoistureMeasurementProcess ⊑ MeasurementProcess
No already-enriched function is co-extensional: MOISTURE (any medium) is explicitly distinct from HUMIDITY (water vapour in air specifically) in ISO 15926-4's own taxonomy, so HumidityMeasurementFunction is not reused; mirrors that sibling's pattern (function_parent=DesignedFunction directly) exactly.
2 Genus DeterminationDeterminação do Gênero
Instrumentbfo:Object (BFO_0000030)
Matches the already-enriched 'humidity analyser' sibling's genus exactly; MEASURING INSTRUMENT (the literal ISO 15926-4 parent) is not itself an enriched cluster, so the concrete genus Instrument is used directly.
3 Differentia SpecificaDiferença Específica
∃bearerOf.MoistureMeasurementFunction

Bears a moisture measurement function: measures and indicates the moisture content of a sample or medium via a digital display.

Functional type: the identity-giving function alone is necessary and sufficient, matching the humidity analyser precedent's minimal differentia pattern.
4 Necessary PartsPartes Necessárias
Part classParentRelation
MoistureSensingElementMaterialArtifacthasComponentPartAtAllTimes
DigitalDisplayMaterialArtifacthasComponentPartAtAllTimes
Both parts are named verbatim in the ISO 15926-4 primary definition itself and are structurally distinct (sensing vs. display), so both are asserted as necessary.

How much independent secondary research backs this term — not how correct it is. "Full" means a non-primary source was quoted directly and covered several distinct aspects of the concept, not just its function. "Partial" means secondary research happened but covered less. "None" means only the primary definition was used. A "full" term can still contain an error, and a "none" term can still be entirely correct — this tracks whether the research step ran, not the result.Quanto de pesquisa secundária independente sustenta este termo — não o quão correto ele é. "Full" significa que uma fonte não-primária foi citada literalmente e cobriu vários aspectos distintos do conceito, não apenas sua função. "Partial" significa que houve pesquisa secundária, mas com cobertura menor. "None" significa que só a definição primária foi usada. Um termo "full" ainda pode conter um erro, e um termo "none" ainda pode estar totalmente correto — isso rastreia se a etapa de pesquisa ocorreu, não o resultado.
