I am trying to implement RBAC using ory keto.I have an API which fetches data from db and i want to restrict user such that a user of a particular type can only access the data . For eg if i have two types of data in my db such as A and B ,what is want is A to be accessed by admin and B to be accessed by other user.how can i achieve this?

yes Keto can totally do that they call it "namespace" what kubernetes calls Resource
