noteAuth0 Fine Grained Authorization (FGA) is the early-stage product we are building at Auth0 to solve fine-grained authorization at scale. Sign up for the Developer Community Preview to try it out, and join our Discord community if you are interested in learning more about our plans. Please note that at this point in time, it is not considered production-ready and does not come with any SLAs; availability and uptime are not guaranteed. Limitations of Auth0 FGA during the Developer Community Preview can be found here. In this short guide, you'll learn how to represent a concentric relationships. For example, if you want to have all editors of a document also be viewers of said document. When to use Concentric relations make the most sense when your domain logic has nested relations, where one having relation implies having another relation. For example:
This allows you to only create a single relationship tuple rather than creating n relationship tuples for each relation. Before you startTo better understand this guide, you should be familiar with some Auth0 FGA Concepts and know how to develop the things listed below. You will start with the authorization model below, it represents a document type that can have users related as editor and viewer. Let us also assume that we have a document called "meeting_notes.doc" and bob is assigned as editor to this document.
type document The current state of the system is represented by the following relationship tuples being in the system already: [ In addition, you will need to know the following: Modeling User GroupsYou need to know how to add users to groups and grant groups access to resources.

Step by StepWith the current type definition, there isn't a way to indicate that all editors of a certain document are also automatically viewers of that document. So for a certain user, in order to indicate that they can both edit and view a certain document, two relationship tuples need to be created (one for editor, and another for viewer). 01. Modify our model to imply editor as viewerInstead of creating two relationship tuples, we can leverage concentric relationships by defining editors are viewers. Our authorization model becomes the following:
type document infoviewer of a document are any of:
With this authorization model change, having an editor relationship with a certain document implies having a viewer relationship with that same document. 02. Check that editors are viewersSince we had a relationship tuple that indicates that bob is an editor of document:meeting_notes.doc, this means bob is now implicitly a viewer of document:meeting_notes.doc. If we now check: is bob a viewer of document:meeting_notes.doc? we would get the following:
Initialize the SDK // FGA_ENVIRONMENT can be "us" (default if not set) for Developer Community Preview or "playground" for the Playground API
NoteWhen creating relationship tuples for Auth0 FGA make sure to use unique ids for each object and user within your application domain. We're using first names and simple ids to just illustrate an easy-to-follow example. Modeling Google Drive See how to indicate that editors are commenters and viewers in Google Drive.
Modeling GitHub See how to indicate that repository admins are writers and readers in GitHub.
