If your team manages identity federation across trust boundaries, you're about to encounter two new OpenID Federation extension specifications. The OpenID Foundation's review and voting process runs from August 21 to September 4, 2026. Regardless of whether you vote, it's essential to evaluate these extensions against your current federation setup.
Here's a checklist to assess readiness for any OpenID Federation extension. Customize it to fit your technical environment and use it before the voting period ends.
Purpose of This Checklist
This checklist helps you determine if a proposed OpenID Federation extension will disrupt, enhance, or complicate your existing federation architecture. Use it when:
- The OpenID Foundation releases a new draft specification.
- Your relying parties or identity providers request a federation feature.
- You're planning a multi-tenant or cross-domain federation deployment.
- You need to justify budget for federation infrastructure changes.
The checklist requires you to map abstract specification language to your actual environment: which systems handle Federation Metadata, where Policy Decision Points evaluate trust chains, and who maintains your Entity Configuration endpoints.
Prerequisites
Before using this checklist, ensure you have:
- A current federation topology diagram showing all entities (Relying Parties, Identity Providers, Trust Anchors).
- Access to your Federation Metadata repository.
- A list of all Entity Configuration endpoints you publish or consume.
- Documentation of any custom trust evaluation logic beyond standard OpenID Federation 1.0 rules.
- Contact information for downstream relying parties who use your federation services.
If you lack these resources, create them first. You can't assess an extension's impact without understanding your current setup.

How to Customize It
For small federations (under 10 entities): Skip section 3.1 and 3.2 counts. Focus on section 2 (technical impact) and section 5.1 (security). You don't have the interop complexity of large federations, but you still need to validate trust chains correctly.
For Open Banking deployments: Expand section 3.3. Add specific FAPI conformance questions: Does this extension modify the Authorization Code Flow? Does it introduce new token types? Does it change how you handle Proof Key for Code Exchange?
For government/eIDAS federations: Add a subsection under 5.2 for assurance level mapping. If the extension changes how you express Level of Assurance in Federation Metadata, you need legal review before implementation.
For hybrid cloud federations: Add infrastructure questions to section 4.1: Which cloud regions host your Entity Configuration endpoints? Does the extension require synchronous metadata updates across regions? Can your CDN cache the new metadata structure?
Replace placeholder fields with your actual system names. "Policy Decision Point" becomes "Keycloak trust evaluator in us-east-1" or "Custom PDP in the API gateway layer." Specificity prevents the checklist from becoming a formality.
Validation Steps
After completing the checklist:
Cross-reference with the specification's security considerations section. Every OpenID spec includes this. If your risk assessment missed something listed there, update section 5.1.
Test one extension feature in staging. Pick the simplest new metadata claim or endpoint. Implement it in your staging federation. Verify that your monitoring catches the change and your logs record it correctly. If this 30-minute test surfaces problems, your production rollout estimate in section 4.1 is too optimistic.
Share with one downstream relying party. Send them section 3.1 of your completed checklist. Ask: "If we implement this extension, does it break your integration?" Their answer validates your interoperability analysis.
Schedule the next review. Federation extensions build on each other. The OpenID Foundation, founded in 2007, releases specifications in waves. If you assess this extension in isolation, you'll miss dependencies. Set a calendar reminder for the next voting period and run this checklist again.
The two-week voting window isn't long enough to do this analysis from scratch. Run the checklist during the 45-day review period, when you still have time to test in staging and consult with partners. By the time voting opens, you should know your decision.
