Profiles

UofA uses a two-tier profile system. Minimal captures the bare evidence package. Complete adds the full credibility assessment.

Minimal Profile

The minimum viable UofA. Suitable for evidence capture during live pipeline execution or as a lightweight audit artifact.

Property	Type	Purpose
`bindsRequirement`	IRI	The requirement this UofA substantiates
`hasContextOfUse`	IRI	The V&V 40 Context of Use for this assessment
`hasValidationResult`	IRI	At least one validation result
`hasDecisionRecord`	IRI	The credibility decision (accepted/rejected + rationale)
`generatedAtTime`	xsd:dateTime	When this UofA was created
`hash`	string	Content hash (format-validated: `sha256:<64 hex chars>`)
`signature`	string	Digital signature (format-validated: `ed25519:<hex>`)

Complete Profile

Extends Minimal with full V&V 40 credibility assessment, provenance chain, and quality metrics. Required for regulatory submissions and formal credibility arguments.

Everything in Minimal, plus:

Property	Type	Purpose
`bindsModel`	IRI	The computational model assessed
`bindsDataset`	IRI	The dataset(s) used in validation
`wasDerivedFrom`	IRI	Provenance link to parent artifact
`wasAttributedTo`	IRI	Responsible actor or organization
`hasCredibilityFactor`	CredibilityFactor[]	Per-factor assessment (V&V 40 Table 5-1)
`hasWeakener`	WeakenerAnnotation[]	(optional) Detected quality gaps
`credibilityIndex`	xsd:decimal [0–1]	Overall credibility score
`traceCompleteness`	xsd:decimal [0–1]	Provenance chain completeness
`verificationCoverage`	xsd:decimal [0–1]	Verification evidence coverage
`validationCoverage`	xsd:decimal [0–1]	Validation evidence coverage
`uncertaintyCIWidth`	xsd:decimal [≥0]	Uncertainty confidence interval width
`assuranceLevel`	string	`Low` / `Medium` / `High`
`criteriaSet`	IRI	Reference criteria set (e.g., `ASME-VV40-2018`)

CredibilityFactor

Each factor maps to one row in V&V 40 Table 5-1 or NASA-STD-7009B:

Property	Constraint	Purpose
`factorType`	Factor name from the active pack’s taxonomy	Which credibility factor is being assessed
`factorStandard`	String (e.g., `"ASME-VV40-2018"`, `"NASA-STD-7009B"`)	Which standard defines this factor
`assessmentPhase`	`"capability"` or `"results"` (NASA-STD-7009B only)	NASA CAS assessment phase
`requiredLevel`	Integer (1–5 for V&V 40, 0–4 for NASA-7009B)	Target credibility level for this COU
`achievedLevel`	Integer (1–5 for V&V 40, 0–4 for NASA-7009B)	Actual credibility level achieved
`hasEvidence`	IRI or IRI[] (optional)	Links to backing evidence entities

WeakenerAnnotation

Quality gap annotations detected by the Jena rule engine (C3). Optional — a UofA with zero weakeners is valid (and desirable).

Property	Constraint	Purpose
`patternId`	Format: `W-XX-NN` or `COMPOUND-NN`	Catalog ID from the weakener pattern taxonomy
`severity`	`Critical` / `High` / `Medium` / `Low`	Impact severity
`affectedNode`	IRI	The specific graph node flagged by this pattern
`description`	string (optional)	Human-readable explanation of why this weakener fires
