OrionBelt Semantic Layer

Open-source semantic sidecar that compiles YAML models into governed SQL, KPIs, and data-quality rules across databases.

PlatformWebfreemium

OrionBelt Semantic Layer is an open-source semantic sidecar that injects governed business definitions into existing analytics and AI systems without requiring an architecture change. Teams define dimensions, measures, and rules once in YAML, and it compiles them into SQL across multiple database dialects, exposed via a REST API, an MCP server, and a direct PostgreSQL connection. It's aimed at data engineers and analytics teams who want a single reusable semantic model for BI tools, AI agents, and data-quality checks.
