# Meeting Notes 2024-01-16 ## New members Welcome 👋 to the NIST team, Cloudentity, Radiant Logic, and Cerbos. ## Prior Art: Cedar Background Darin's [AWS Cedar Overview](https://docs.google.com/document/d/1FAwPXX3dN1sOB8ICihP9rqC4TDtjsZs2cOuE0pYa29Q/edit) - There is consensus that we are trying to harmonize how to send a request and process a response - Cedar uses the PARC model. Atul's current design doesn't have room for context. We need to add that - Cedar's model is symmetric i.e. Principal, Action, Resource, and Context are all equivalent. - Passing in the policies that are to be crunched: @davidbrossard seems to think it's out of bounds - Passing in the data to be used: that goes against the PIP model but addresses issues of scale ## Action Items - @davidbrossard will build a comparison between different models in the prior art doc to drive the next iteration of the spec - We need to agree on what we want to show in the interop - Is it a Postman collection that can be used against any vendor (Aserto, Axiomatics, 3Edges?) ## Next Steps - 2 calls scheduled to go over OAuth (David Hyland) and ALFA (David Brossard) on Thursday and Friday 11am PT - Design patterns doc (@alexbabeanu): Alex will schedule a follow-up ## Other Items - Identiverse participation: interop exercise prior to the conference followed by a readout during the main agenda - All, please read up @xmlgrrl's [interop scenarios](https://hackmd.io/@oidf-wg-authzen/InteropScenarios)
