A.2.6:20.1.2 - UTS Table (F.17) — Cross‑context term mapping
#Context / SourceLocal label(s) (native)Closest USM conceptNotes on fit & deltas
1ISO/IEC/IEEE 42010Architecture context; environment; stakeholder concerns; viewpoints and viewsContextSlice (addressable slice); Scope as view‑specific applicability42010 is about views in context; it has no first‑class set‑valued scope char but aligns with “evaluate in a concrete context” → USM uses explicit slice tuples.
2OMG EssenceAlpha State; Work Product State; Level of Detail (LoD)Work scope (guards), Detail (D) (LoD), ESG/RSGEssence separates status (states) and work evidence; LoD is detail, not scope. USM treats scope as guardable membership over slices; states/LoD map to ESG & D, not to G.
3NIST AI RMFContext of use; validity, reliability, robustness; monitoringClaim scope (G); R freshness/monitoring“Context of use” = where a claim/model holds → maps to G. “Validity” is part of R vocabulary; we avoid naming the characteristic “validity” to prevent LA confusion.
4ASME V&V 40 / FDAContext of use; credibility factors; verification/validationClaim scope (G); R (credibility)Direct fit for G via “context of use”. Credibility/evidence freshness contribute to R, not to G; USM keeps them separate in guards.
5W3C SHACLShapes; targets (sh:targetClass, sh:target); constraintsClaim scope (targets define where constraints apply); F≥4 (predicate form)SHACL “target” ≈ membership predicate on a dataset context; analogue of Claim scope on data slices; constraint language supports F4‑style predicates.
6OWL 2 practiceClass extension; domain/range; imports/version IRIClaim scope as class extension over an ontology contextClass extension is set‑semantics by design; G maps to extension over a versioned ontology (part of ContextSlice).
7IETF BCP 14MUST/SHALL/SHOULD; requirements languageGuard style (observable predicates)BCP 14 doesn’t define scope but dictates how guards are worded; USM aligns by requiring observable, deterministic membership checks.
8DO‑178C / DO‑333Operational conditions; DAL; formal method objectives; TQLWork scope (operating conditions); F (proof‑grade), R (assurance objectives)Operational applicability = Work scope; formal method objectives lift F; Tool qualification impacts TA/R, not G.
9ISO 26262Operational situation & operating modes; ASIL; OSEDWork scope (operating modes/situations)OSED/operating modes define where capability can be exercised → Work scope. Assurance level (ASIL) relates to R, not G.
10IEC 61508SIL; demand mode; proof test intervalWork scope (demand vs continuous mode) + R freshnessMode concepts influence where/how a function can be claimed → Work scope; proof test interval sits in R (freshness/decay).
11ACM ArtifactsAvailable/Evaluated/Reusable; Reproduced/ReplicatedR signals; ContextSlice (reproduction environment)Badges encode evidence availability and warrant level; the declared environment maps to a slice; scope of claim is often implicit → USM makes it explicit.
12SRE / Cloud SLOSLOs; error budgets; regions/tiers; rollout windowsWork scope (regions/tiers) + measures; gammaTime only for a membership-changing rollout intervalSLO measures and error-budget windows stay in their measure or reliance guards. A rollout interval enters Work scope only when crossing its exact start or end changes whether that job slice belongs.

Summary. Across all Contexts, two stable notions recur: (1) evaluate in a concrete context (→ U.ContextSlice), and (2) declare where something holds or is deliverable (→ set‑valued Scope). “Context of use,” “operating modes,” “targets,” “class extension,” and “OSED” are all Context‑flavored presentations of Claim scope or Work scope. Terms like validity and operation are semantically close but collide with LA and FPF’s Work and Run lexicon; we therefore do not adopt them as characteristic names.
