 * Core:
     * Keycloak is responsible for handling the authentication with the standard OpenID Connect and manages user access with its Role Model.
-    * Keycloak is configured with a new custom extension :rocket: [keycloak-openfga-event-publisher](https://github.com/embesozzi/keycloak-openfga-event-publisher) which listens to the Keycloak events (User Role Assignment, Role to Role Assignment, etc), parses this event into an OpenFGA tuple based on the [Keycloak Authorization Schema](model.dsl) and publishes them to OpenFGA over HTTP.

+      * Publishes them to OpenFGA over HTTP using the [OpenFGA Java SDK](https://github.com/openfga/java-sdk).
     * OpenFGA is responsible for applying fine-grained access control. The OpenFGA service answers authorization checks by determining whether a relationship exists between an object and a user.
 * Other components
     * Store Web Application is integrated with Keycloak by OpenID Connect
     * Store API is protected by OAuth 2.0 and it utilizes the OpenFGA SDK for FGA
