+-------------------------------------------------------
+
+These resource fields are examples on how Drools-PDP implements its "guard" application to make Decision API calls. This
+structure is a transition from the legacy guard API calls. So each of these resources are contained under a "guard" object
+in the "resource" object of the JSON structure.
