How can AP242 and QIF answer one configuration-bound inspection question?
In this constructed case, a quality engineer asks: “For released product-definition revision and configuration R, which QIF inspection plan and result concern feature F at effectivity E?” AP242 and QIF use different models and identifiers. The useful result is not a universal merged model; it is an inspectable answer package for this query.
Start with SIE.1 - Bound the Receiving Use and Semantic Contract. Name the engineer and receiving workflow, the exact answer columns, the required revision/configuration/effectivity grain, permitted unmatched rows, freshness and provenance requirements, negative cases, authority boundary, stops and reopen conditions. Systems Engineering and the authorized quality practice still decide which configuration is released, which plan applies and whether an inspection result is accepted.
Build only the semantic premises and returns the query consumes:
| Contribution | Result needed for the query |
|---|---|
| SIE.2 - Recover and Qualify Source Semantics and Authority | Inventory AP242:2025 edition 4 at current stage 90.92, “to be revised”, the applicable ISO 23952:2020 QIF carrier/profile, source-local feature, characteristic, plan, result, configuration and effectivity meanings, identifiers, owners, access and unresolved extensions. |
| SIE.4 - Judge Cross-Source Correspondences and Their Permitted Uses | Record directional correspondences for product feature, inspection characteristic, plan applicability, configuration and result relations. Keep unsupported equivalence and incompatible-feature rows explicit. |
| SIE.5 - Resolve Cross-Source Identity without Erasing Identifier Authority | Establish the supported cross-source identity relations for features and inspection characteristics at the required revision, configuration and effectivity. Preserve each source’s identifiers and issuers. A QIF result identifier does not establish AP242 feature identity. |
| SIE.6 - Fuse Source-Qualified Claims without Erasing Conflict | Compose AP242 definition/effectivity claims and QIF plan/result claims with source, interval, authority and conflict branches preserved. |
| SIE.7 - Specify Semantic Extraction and Transformation Mappings | Specify executable rules that select the named released configuration, use only accepted endpoint relations, preserve identifiers, reject unsupported joins and trace every output row to its premises. |
| SIE.8 - Choose Virtual, Materialized, or Hybrid Semantic Realization and SIE.9 - Connect a Receiving Use through a Semantic Interface | Choose a virtual, materialized or hybrid realization from freshness, access, latency, provenance and recovery needs. Return matched, unmatched, incompatible, stale and source-error branches with their interpretations and provenance. |
| SIE.10 - Validate a Semantic Integration Result for Its Receiving Use | Test carrier/schema, source semantics, correspondence, identity/effectivity, claim composition, transformations, provenance/currentness, quality and the representative query, including negative and unlike cases. |
The bounded positive return is a validated row set for R, F and E, plus explicit unmatched or incompatible results. If an unresolved local AP242 extension affects one feature class, stop that row and return to its owner while independent rows may continue. Stop the dependent answer if configuration/effectivity or feature identity is unresolved, a load-bearing source edition cannot be qualified, a conflict is hidden, or the representative query fails.
Pass the resulting semantic premise to the applicable Systems Engineering and quality decisions. It does not choose the released revision, decide plan applicability, accept an inspection result, prove the integration is deployed, or show that a pipeline is reliable. Real work must substitute the actual source assets, local extensions, configurations, inspection records, authority and tests; this case demonstrates the method and its stopping boundaries.
