We are pleased to announce an InCommon Federation community consultation for the new guidance document, Deploying Subject Identifiers for InCommon Federation Participants.
This consultation is open through Aug. 31, 2025, at 8 p.m. ET. You will need to sign into the Internet2 wiki to post your feedback — and we hope you will.
Your input will help shape the final guidance to support interoperable, privacy-preserving deployments across the federation.
What is Deploying Subjectifiers Guidance?
This document was prepared by a community working group chartered by the InCommon Technical Advisory Committee (TAC). It provides deployment guidance to help InCommon Federation participants adopt and manage the subject-id and pairwise-id attributes as defined in the OASIS SAML V2.0 Subject Identifier Attributes Profile.
The guidance outlines identifier characteristics, generation strategies, privacy considerations, and deployment options across identity management platforms and services. It also addresses migration from legacy identifiers, such as eduPersonTargetedID.
A Forum for Your Feedback
This consultation provides an opportunity for the InCommon community to review the draft, suggest improvements, and help shape the final version.
You’ll find the proposed guidance and a feedback log here: Deploying Subject Identifiers for InCommon Federation Participants.
