Rxis

Rxis is a fictional, open architecture for interoperable data and energy exchange designed for smart urban infrastructures. It provides a standardized interface for devices, applications, and services to exchange information and coordinate energy usage in real time.

The acronym is commonly expanded as Reflected Cross-Index System. It originated in mid-22nd century science fiction as a theoretical standard and was adopted by worldbuilding communities and game designers to model interoperable urban systems.

Rxis comprises three layers: a data plane for messaging, a control plane for policy and orchestration, and an energy management module for coordinating supply and demand. The Rxis Protocol supports publish-subscribe, request-response, and streaming patterns with end-to-end security.

Applications include smart grids, autonomous transit, building management, and simulation platforms that model city-scale energy flows and data exchange.

In-universe reception notes that Rxis enables high interoperability among diverse devices but raises concerns about complexity, governance, and potential centralization risks if implemented without clear standards.
