Comparable claims
State exactly which version, object set and behaviour an implementation supports.
Assurance layerProgramme in development
OATI Certified
Make compatibility a testable claim.
OATI Certified is the planned conformance and assurance programme for implementations, issuers and enterprise controls. Certification will be tied to published OATI and conformance-suite versions, with evidence of behaviour rather than a logo based on self-declaration.
The question it answers
“Does this implementation behave as the standard requires?”
Executable evidence
Use schemas, fixtures and conformance tests to demonstrate interoperability.
Layered assurance
Distinguish basic compatibility from issuer, enforcement, verification and enterprise assurance.
How it works
A precise part of the trust chain.
Each OATI component has one clear job. Together they create a transaction that another organisation can understand and verify.
- 01
Choose the profile
An implementer selects the applicable OATI version, component and certification mark.
- 02
Run conformance
The implementation passes required positive, negative, cryptographic and privacy tests.
- 03
Publish the claim
A versioned result and certification status can be checked by counterparties.
In the profile
Planned certification marks
- OATI Compatible
- OATI Passport Issuer Certified
- OATI Mandate Enforcement Certified
- OATI Receipt Verification Certified
- OATI Enterprise Assurance
Use the standard
Check published assurance
Inspect the assurance level and proof state published for an agent. Certification marks remain versioned and scope-specific.
