PlaceAuth Gives Places a Protocol for Admitting Machines
PlaceAuth proposes an open interoperability layer through which physical environments express machine-readable requirements and autonomous systems present evidence of conformance.
Field notes
The SPP model divides the exchange into spatial requirements, conformance evidence, and an operating profile. Its example policy inherits from a hospital policy, denies video retention in a patient area, makes pharmacy entry conditional on staff authorization, and lets elevator access expire after 30 seconds. The homepage labels SPP 0.1.0 an experimental Apache-2.0 release and links to specification, security, contributing, and repository materials.
