SIE.4:5 - Archetypal Grounding - Product Feature and Inspection Characteristic
In the AP242/QIF application, the lexical candidate feature ↔ characteristic is too broad. The source inventory distinguishes an AP242 product-definition feature, a QIF inspection characteristic, the plan relation that applies a characteristic to a feature, and a measured result concerning that characteristic.
| Candidate row | Direct relation judgment | Use qualification and disposition |
|---|---|---|
AP242 feature F-17 ↔ QIF characteristic C-17 | not identity and not class equivalence; the QIF plan asserts that C-17 concerns the identified product feature under configuration/effectivity R/E | accepted-for-use as a directed inspection-characteristic-concerns-feature relation only after SIE.5 qualifies the feature endpoint; no reverse substitution |
AP242 feature type hole ↔ QIF characteristic type diameter | a diameter characteristic can characterize some holes, but the types are neither equal nor simply broader/narrower | accepted-for-use for navigation from a selected plan row with a qualified feature endpoint to its linked hole feature and diameter characteristic. Return their separate source identifiers and types with the plan relation; forbidden as a global type crosswalk |
AP242 feature F-22 ↔ QIF characteristic C-99 | the candidate arose from a shared local label; effectivity and plan evidence do not support the relation | rejected; the interface returns unmatched rather than joining |
| legacy feature class ↔ current QIF characteristic class | one local extension lacks an authoritative definition | unresolved and stopped for dependent mapping; return to the extension owner |
The set records endpoint editions and counterexamples such as a non-dimensional inspection characteristic and a feature absent at effectivity E. It establishes semantic premises; it does not decide that identifiers denote the same entity or specify executable joins.
