Source catalog · the registry, live

The research-data landscape, mapped.

Finding any dataset means knowing where data lives, how it's indexed, how it's described, and how it connects. This catalog is the single source of truth - served from GET /v1/source-catalog, it maps that landscape and marks what Meridian has onboarded.
