XAPI 2.0 — certification dossier

Generated by bun run conformance:render — do not edit by hand.

Point-by-point certification submission: every conformance requirement against the literal published schema (conform-ed ADR-0013), with emergent’s implementation status, the spec citation, the modelled schema anchors, and the verifying evidence (emergent ADR-0028).

  • Denominator: pinned Coverage Map docs/conformance/maps/xapi-v2.0.json (generated 2026-06-22), sha256 dc8dc9395db83ffe611b1ec1e593b9d35ef9f141b7ae7a151ee9188b04f937a5.
  • Requirements: 11/11 done across 3 profile(s) — attachment, context, statement.
  • Information model: 92/125 literal items modelled.
  • Evidence: each claim cites its [covers:] evidence key; run bun run conformance:prove to resolve these to the proving test names for a submission copy.

Profile: context — 2/2 done

Section titled “Profile: context — 2/2 done”
Req Level Status Statement Verified by / justification Spec source
XAPI-CTX-1 MUST ✅ done When a Context references an Activity through contextActivities, each of parent, grouping, category and other is a list of Activities. xapi:2.0:conf:context/XAPI-CTX-1 IEEE Std 9274.1.1-2023 (xAPI Base Standard, Part Two: Data) — https://opensource.ieee.org/xapi
