CLR 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/clr-v2.0.json (generated 2026-06-22), sha256 8a10283a194fbcfce0132387c4ae9683a1119b04e9fd8ff239b6daa6e0e203db.
  • Requirements: 14/14 done across 3 profile(s) — displayer, host, issuer.
  • Information model: 299/409 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.

Section titled “Profile: displayer — 5/5 done”
Req Level Status Statement Verified by / justification Spec source
CLR-DSP-1 MUST ✅ done A displayer MUST verify a presented ClrCredential and correctly determine its state — valid, expired or revoked — before display, and MUST allow a viewer to trigger verification and retrieve the result. clr:2.0:conf:displayer/CLR-DSP-1 CLR 2.0 Cert §4.2 (Displayer Tests) — https://www.imsglobal.org/spec/clr/v2p0/cert/#displayer
CLR-DSP-2 MUST ✅ done A displayer MUST present the record’s name, description, issuer name, issue date (validFrom), verification status, and the image when present. clr:2.0:conf:displayer/CLR-DSP-2 CLR 2.0 Cert §4.2 (Displayer — displayed data) — https://www.imsglobal.org/spec/clr/v2p0/cert/#displayer
CLR-DSP-3 MUST ✅ done A ClrCredential MUST be treated as expired when the current date-time is after its validUntil. clr:2.0:conf:displayer/CLR-DSP-3 CLR 2.0 Cert §4.1 (Verification and Status — expired) — https://www.imsglobal.org/spec/clr/v2p0/cert/#status
CLR-DSP-4 MUST ✅ done A ClrCredential MUST be treated as revoked when credentialStatus is present with type ‘1EdTechRevocationList’; credentialStatus.id MUST be the URL of the issuer’s credential status method. clr:2.0:conf:displayer/CLR-DSP-4 CLR 2.0 Cert §4.1 (Verification and Status — revoked) — https://www.imsglobal.org/spec/clr/v2p0/cert/#status
CLR-DSP-5 MUST ✅ done A displayer MUST support the Data Integrity proof cryptosuites and MUST verify credentials expressed against the W3C VC Data Model 2.0 context. clr:2.0:conf:displayer/CLR-DSP-5 CLR 2.0 Cert §4.2 (Displayer — VC 2.0 + proof) — https://www.imsglobal.org/spec/clr/v2p0/cert/#displayer
