In this episode, Clemens introduces CNCF xRegistry (xregistry.io), explains how it evolved from CloudEvents work in the CNCF Serverless Working Group, and shows why teams need machine-readable metadata for events, schemas, and endpoints to build reliable event-driven systems. He walks through the core idea of an extensible, model-driven registry with consistent APIs, built-in versioning, and support for common formats and protocols, then highlights the surrounding tooling (server, CLI, code generator, and viewer). The episode closes with a practical look at how Microsoft Fabric uses xRegistry concepts to power typed event pipelines and schema-aware integration, and previews deeper dives in upcoming sessions.
