Trust criteria

Five versioned indices — no sixth composite “truth” score. Version: mvp-2026-08

Freshness

Measures: Dates, versions and signals of dated content.

Auto / human: Auto when signals are clear; lower level if undated.

What it is not: Not a guarantee of absolute pedagogical currency.

Licence clarity

Measures: Consistency between declared licence and signals in the resource.

Auto / human: Auto if consistent; always human review on conflict.

What it is not: Not legal advice.

Metadata completeness

Measures: Coverage of required / optional LRMI fields.

Auto / human: Auto. Empty optional fields lower the level without blocking alone.

What it is not: Not a rating of pedagogical content quality.

Accessibility

Measures: Technical / readability signals (structure, alternatives, limits by type).

Auto / human: Partial auto; gaps → lower level or N/A.

What it is not: Does not claim full RGAA/WCAG certification.

Sources and references

Measures: Identifiable author/organisation and presence/consistency of references.

Auto / human: Auto only if trivially clear; otherwise AI assistance + human.

What it is not: Not a measure of “truth” or absolute credibility.
