rawctx is a package registry for semantic models like npm, but for dbt MetricFlow, OSI, and Cube definitions. Semantic model sharing is becoming real. Several companies recently agreed on a common format called Open Semantic Interchange (OSI) and released v1.0. rawctx is built to be the neutral registry that no single vendor can own - a place to publish, discover, and reuse semantic packages across tools and organizations. + There's also a private workspace.
