OpenFGA — Modelling patterns & RBAC→ReBAC migration

OpenFGA — Patterns & RBAC→ReBAC migration — study / POC

The through-line of the series. After several POCs, this work consolidates the reusable patterns and a migration method from classic RBAC.

What I document / prototype

• Patterns: groups, inheritance, ownership, sharing, temporary delegation.
• RBAC → ReBAC migration method: map roles → relations without a big bang.
• Authorization tests (check assertions) as a safety net.
