There is no translation doc per-se. I'm not super familiar with OPA terminology either, but from a cursory google: PEP -> policy enforcement point -> in zed this would most likely be an if statement calling out to one of our client libraries in your code, or a custom written plugin to act as an authorization middleware in your framework of choice PDP -> policy decision point -> authzed/spicedb itself PIP -> policy information point -> no such equivalent in authzed, you can use zed/playground to figure out if your schemas are working/correct, and then you can use zed to run specific queries APIGW -> not an OPA/ABAC component? presumably this means using a PEP for guarding API calls, which again you would do with a custom middleware
