This repository contains the source for a nunber of FHIR packages the provide important implementation time support for FHIR implementers:

These packages are the master source for the FHIR NPM packages that represent the base FHIR specification

• hl7.fhir.core - wrapper package for the core specification, has multiple versions
• hl7.fhir.r[X].core - The base resources needed for validation, code generation etc.
• hl7.fhir.r[X].corexml - The base resources in XML format instead of JSON (all the other packages have json)
• hl7.fhir.r[X].examples - All the examples in the spec (including all the core resources, with narrative)
• hl7.fhir.r[X].elements - A set of data element definitions for all the resources in the spec
• hl7.fhir.r[X].expansions - expansions for all the value sets used as enumerations in the spec - to help with code generation

All these packages are found under /hl7.fhir.rX

A set of resources that support implementers converting resources across versions.

• conversion - Resource and Search Parameter name mappings
• r3 - maps between R2 and R3 (both directions)
• r4 - maps between R3 and R4 (both directions)

All these resources are found under /interversion. They are distributed in the packages hl7.fhir.xver.r4 and hl7.fhir.xver.r3 (both contain the same content, but in different FHIR versions)

The folder /packages also contains the source for hl7.fhir.xver-extensions, a special package that contains the source to allow the validator to validate cross-version extensions, as described in the R4 specification.

• fhir.test.data.r[X] - Contains useful test data (synthetic data from Synthea)
• fhir.tx.support.r[X]- Contains useful support terminology resources for terminology servers
• hl7.fhir.pubpack - Special package that contains the images and other binary files used in FHIR Implementation Guides

These packages are in /packages

Pull requests are welcome. Updated versions of these packages are released in NPM by the FHIR Product Director. The core packages are under the authority of the FMG
