(OPA co-founder here.) The semantics of OPA's policy language are based on Datalog, a non-Turing complete subset of Prolog. This means that all policy queries in OPA are guaranteed to terminate (which makes it a good fit for problems l

OPA draws some inspiration from XACML. For example, OPA helps systems separate policy decision-making from policy enforcement. Decoupling means that policy decisions can be more easily updated and more readily understood. XACML as a specifi

Hello! The semantics are based on Datalog--but we've added a few features that make it more expressive than just plain Datalog. For example, OPA has first-class support for accessing nested data structures like JSON. At the same time,

There are a few ways of doing this. 1. You can include JSON data as input when you execute a policy query. In your example, you could include the management hierarchy or a user in a JWT that's provided as input to the policy query. 2.
