Cross Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (de.medizininformatikinitiative.kerndatensatz.meta.r4) and R4B (de.medizininformatikinitiative.kerndatensatz.meta.r4b) are available.

IG Dependencies

This IG contains the following dependencies on other IGs.

Package hl7.fhir.uv.extensions.r4#5.2.0 This IG defines the global extensions - the ones defined for everyone. These extensions are always in scope wherever FHIR is being used (built Mon, Feb 10, 2025 21:45+1100+11:00)

Package hl7.fhir.uv.extensions.r4#5.3.0 This IG defines the global extensions - the ones defined for everyone. These extensions are always in scope wherever FHIR is being used (built Sat, May 16, 2026 18:32+1000+10:00)

Package hl7.fhir.uv.crmi#2.0.0 This implementation guide defines profiles, operations, capability statements and guidance to facilitate the content management lifecycle for authoring, publishing, distribution, and implementation of FHIR knowledge artifacts such as value sets, profiles, libraries, rules, and measures. The guide is intended to be used by specification and content implementation guide authors as both a dependency for validation of published artifacts, and a guide for construction and publication of content. (built Thu, Jul 2, 2026 00:17+1000+10:00)

Package hl7.fhir.uv.tools.r4#1.1.2 This IG defines the extensions that the tools use internally. Some of these extensions are content that are being evaluated for elevation into the main spec, and others are tooling concerns (built Tue, Mar 24, 2026 11:13+1100+11:00)

Where the versions come from. Every package in the table is pinned directly in sushi-config.yaml (dependencies:) — including hl7.terminology.r4 (THO) and hl7.fhir.uv.extensions.r4, and those two deliberately so: the IG Publisher's automatic-packages rule consults only this guide's own dependency list, so without a direct pin every build would silently inject the latest THO/extensions release — a version pinned by the MII meta package alone cannot control the build (verified in the publisher source at the pinned release). A weekly check warns when these two pins drift from what the pinned meta package ships, and the exact versions a concrete build used are recorded in its qa-versions.json output.

Global Profiles

This IG declares the following global profiles — profiles that apply to every instance of their resource type exchanged under this guide. An empty table means this module declares none.

There are no Global profiles defined

Copyrights

No use of external IP (other than from the FHIR specification)

IG Parameter Settings and Expansion Parameters

Expansion parameters are query parameters that can be passed to a ValueSet $expand operation to control how the ValueSet is expanded — that is, how the full list of codes is generated from the ValueSet definition. The IG Parameters used for this IG are declared in sushi-config.yaml (parameters:). This module pins its expansion parameters through the Meta expansion manifest; see the Metadata Overview.
