Farmer Registry
Farmer Registry is a manifestation of OpenG2P Registry Platform with specifics related to a farmer registry.
This registry contains the following registers:
Farmer Register
Household Register
The domain models for these registers are available in the extensions repository.
The Farmer Registry inherits all the features of the registry platform.

Farmer Registry follows the branch-name-equals-version convention: the develop branch carries -develop pre-release tags on both the wrapper chart and all Docker images. Release branches drop the suffix and produce versioned artefacts (e.g. 1.1.0).
Source code at the 1.1.0 tag: github.com/OpenG2P/farmer-registry/tree/1.1.0
For platform-level release notes (which manifest Farmer Registry releases), see Registry versions.
Domain models
Each domain model below represents a database table in the Farmer Registry. The Farmer and Household models are registers (extending the core G2PRegister base); the remaining models are supporting tables that store related data linked to a register record. All models extend core platform base classes and add domain-specific columns. Fields inherited from the base classes (such as internal_record_id, functional_record_id, record_name, status, name fields, date of birth, gender, geo coordinates, address etc.) are not repeated here.
Core base classes:
G2PRegister
Abstract base for all registers — provides internal_record_id, functional_record_id, record_name, status, link_internal_record_id, and change management fields
G2PPerson
Mixin for person-level fields — given name, family name, additional name, date of birth, gender, marital status, foundational ID, email, phone
Every register model has a corresponding History table (e.g., g2p_register_history_farmers) with the same domain columns, used for version snapshots. History tables are not listed separately below.
