Roles & implementations

A non-normative map of distinct sponsor, property-management, physical-infrastructure, software-operation, and workflow-engineering roles around tenant-governed sovereign environments.

Role architecture

Different layers. Clear responsibilities.

The specification defines the reference. Commercial parties implement distinct property, infrastructure, and software responsibilities around it.
