FHIR, pronounced "fire," stands for Fast Healthcare Interoperability Resources. FHIR is standard for exchanging healthcare information between different systems, designed to be flexible and easy to implement. It uses modern web technologies like RESTful APIs and JSON, XML, or RDF for data representation.
FHIR provides multiple releases. The current release as of 2024 is release 5 which is known as "R5".
This repository contains the worldwide-compatible FHIR R5 specifications files using JSON, and explains how to create this repository for yourself if you wish.
On the FHIR R5 downloads page, the most important file is the definitions file. This is the master set of worldwide-compatible definitions that should be the first choice whenever generating any implementation artifacts.
