Introduction

This IG defines extensions and their valuesets + code systems used internally by FHIR tools that support the implementation community. These tools include:

• Validators
• Code Generators
• Profile & Terminology tooling
• Implementation Guide Authoring Tooling

These extensions are not intended to appear in health systems implementations unless they are concerned with code generation from the FHIR packages.

In addition, there are a few extensions and logical models that are defined in this IG to allow for experimental use; once more experience has been gained, these are intended to move into the main FHIR Extensions package (at which time their URL will change). Those extensions and the supporting terminology resources are clearly labeled.

Tooling IG Lifecycle

This IG is not subject to formal balloting. It is maintained by the FHIR-I Working Group on behalf of the tooling providers, and updated regularly to keep in sync with the various tools. Changes are proposed and managed using the standard Jira process (see right link on the footer).
