# Building a Registry

OpenG2P Registry is a domain-agnostic core. To create a registry for a specific domain (Farmer, Vehicle, Health Worker, etc.), you extend the core with domain-specific ORM models, Pydantic schemas, and metadata configuration. This section covers the concepts, patterns, and step-by-step guidance.
