Yes, your requirement is clear. You want to create a relationship where a user with email X has the same permissions as the 'superuser'. This can be achieved by creating a relationship where the 'superuser' is the 'subject_set' and the user with email X is the 'subject_id'. Here is an example of how you can structure your request:

json PUT <http://localhost:4467/admin/relation-tuples/> {   "namespace": "data-reference-app",   "object": "country",   "relation": "read",   "subject_id": "user_with_email_X",   "subject_set": {     "namespace": "data-reference-app",     "object": "country",     "relation": "read"   } }

In this request, 'user_with_email_X' is the 'subject_id' and the 'superuser' is represented as the 'subject_set'. This means that 'user_with_email_X' will have the same permissions as the 'superuser'. Please replace 'user_with_email_X' with the actual email of the user. This is based on the information provided in the [Ory Keto API documentation](https://www.ory.sh/docs/keto/reference/rest-api) for creating a relationship.

In Ory Keto, a subject set is a set of all subjects that have a specific relation on an object. In your case, the 'superuser' has a 'read' relation on the 'country' object in the 'data-reference-app' namespace. This is represented as a subject set. When you add this subject set to the relation tuple for 'user_with_email_X', you are essentially saying that 'user_with_email_X' has the same permissions as all subjects in the subject set. Since the 'superuser' is the only subject in this set, 'user_with_email_X' will have the same permissions as the 'superuser'. However, I apologize for the confusion, but upon reviewing the knowledge sources, it seems there might be a misunderstanding. The 'subject_set' field in the relation tuple is not used to inherit permissions from another user. Instead, it is used to define a set of subjects that have a specific relation on an object. To achieve your requirement of having 'user_with_email_X' inherit permissions from 'superuser', you would need to implement this logic in your application. This could be done by checking if a user is a 'member' of 'superuser' and then granting them the same permissions. For more information on subjects and subject sets, you can refer to the [Ory Keto documentation on subjects](https://www.ory.sh/docs/keto/concepts/subjects).

To implement this logic, you would need to create a new relation that represents the 'member' relationship between 'user_with_email_X' and 'superuser'. Then, when checking permissions for 'user_with_email_X', you would also check if they are a 'member' of 'superuser' and if so, grant them the same permissions. Here's a high-level overview of how you could implement this: 1. Create a 'member' relation: You would need to create a new relation that represents the 'member' relationship. This could be done by creating a new relation tuple where 'user_with_email_X' is the 'subject_id' and 'superuser' is the 'object'. The 'relation' would be 'member'. Here's an example of how you could structure this request:

json PUT <http://localhost:4467/admin/relation-tuples/> {{   "namespace": "data-reference-app",   "object": "superuser",   "relation": "member",   "subject_id": "user_with_email_X" }}

2. Check 'member' relation when checking permissions: When checking if 'user_with_email_X' has a certain permission, you would also need to check if they are a 'member' of 'superuser'. If they are, you would grant them the same permissions as 'superuser'. This would require modifying your permission checking logic in your application. Please note that this is a high-level overview and the exact implementation would depend on the specifics of your application and how you have set up your Ory Keto server.

Yes, you can configure Ory Keto to determine a user's role based on their email. This involves creating relation tuples that associate a user (identified by their email) with a specific role. Here's an example of how you could structure a relation tuple to associate a user with a role:

json PUT <http://localhost:4467/admin/relation-tuples/> {{   "namespace": "roles",   "object": "admin",   "relation": "member",   "subject_id": "user_with_email_X" }}

In this example, 'user_with_email_X' is the user's email and 'admin' is the role. The 'relation' is 'member', indicating that the user is a member of the 'admin' role. To check a user's role, you would use the

keto relation-tuple get

command with the user's email as the

--subject-id

parameter. Here's an example:

bash keto relation-tuple get --subject-id=user_with_email_X --relation=member --format json --read-remote localhost:4466

This command would return a list of all relation tuples where the user is the subject, allowing you to determine their role. Please replace 'user_with_email_X' with the actual email of the user.
