Generic Functions for Wellbeing (Gezondheid en Welzijn) — FHIR Implementation Guide

This repository contains the FHIR Implementation Guide for Generic Functions for Wellbeing (Generieke Functies Gezondheid en Welzijn), published by Stichting GIDS Open Standaarden.

It defines the generic functions needed for citizen-driven, community-based digital data exchange in the context of health promotion, prevention, and wellbeing — complementing the Generic Functions for Healthcare (Zorg) published by Stichting Nuts, which focuses on professional healthcare delivery (cure and care).
