Workload Identity in Multi System Environments (WIMSE) Architecture vs WIMSE AI Identity Management System (AIMS)
The map lists them as complementary: sites and agents commonly implement both. Workload Identity in Multi System Environments (WIMSE) Architecture is a prerequisite of WIMSE AI Identity Management System.

| Lifecycle step | 2 Identify: Who is this agent? Who is this site? | 2 Identify: Who is this agent? Who is this site? |
| Answers | How do workloads — including, per a related draft, AI agents — authenticate to each other and to services across platforms and trust domains? | What are the best practices for authenticating and authorising interactions between AI agents and the services they call? |
