FHIR Infrastructure icon Work Group Maturity Level : N/A Standards Status : Informative
Validator The official FHIR validator - a Java jar file that can be used
Specification Downloads
FHIR Definitions All the value sets, profiles, etc. defined as part of the FHIR specification, and the included implementation guides: This is the master set of definitions that should be the first choice whenever generating any implementation artifacts. All the other forms below include only subsets of the information available in these definition files, and do not contain all of the rules about what makes resources valid. Implementers will still need to be familiar with the content of the specification and with any profiles that apply to the resources in order to make a conformant implementation.
XML
JSON
RDF
GraphQL
FHIR Specification The whole specification so that you can host your own local copy (does not include the downloads)
Implementation Tools
In addition to validate resources. See Validation Tools for further information, or Using the resources listed below, the HL7 Confluence contains an overview of commonly used tools to help with implementing FHIR Validator for parameter documentation IG Publisher The Implementation Guide Publishing Tool (see IG Publishing documentation icon ) .
NPM Packages There are several packages that support the FHIR specification:
  • hl7.fhir.r4b.core hl7.fhir.r5.core : Contains all the resources needed to test conformance to the FHIR specification, and/or generate code
  • hl7.fhir.r4b.expansions hl7.fhir.r5.expansions : Contains the expansions of the subset of the value sets the have a required binding (other than those that can't be expanded at all)
  • hl7.fhir.r4b.examples hl7.fhir.r5.examples : All the resources that are defined as part of the FHIR specification
  • hl7.fhir.r4b.elements hl7.fhir.r5.search : A set of StructureDefinition resources that represent Just the resources and data types as search parameters. In this package, the combined search parameters are uncombined so that there is a series set of independently defined data elements search parameters for each resource (performance considerations)
  • hl7.fhir.r4b.corexml hl7.fhir.r5.corexml : The same content as hl7.fhir.r4b.core, hl7.fhir.r5.core, but with the resources in XML, not JSON
These packages are used by many of the FHIR tools (e.g. the IG publisher and the validator). Note that the tools usually find this package directly through the NPM-based distribution framework, and there's no need to download them
Spreadsheets All the resource structures in a Spreadsheet Format - mostly provided to assist with mapping
Translation File Translations of common FHIR names and messages into multiple languages (see chat.fhir.org translations stream icon for guidance on how to add to more)
Icon Pack The FHIR Icon at various resolutions icon . Any FHIR Implementation created by an organization that has attended a connectathon is allowed to use the FHIR icon in association with the application (this policy will be reviewed in the future).
Test Cases Test cases can mainly be found in the org.hl7.fhir.core fhir-test-cases icon repository
Code Generation Support ValueSet expansions for the value sets used in schema generation ( XML or JSON ) + a list of all choice elements & backbone elements . Note that names relevant for code generation, including resource names, element & slice names, codes, etc. may collide with reserved words in the relevant target language, and code generators will need to handle this
Reference Implementations
There are many open source reference implementations available to help implementers. Here are a A current list of the more common implementations used by implementers: Java HAPI-FHIR : Object Models, Parsers, Client + Server Framework, FHIR Validator, & Utilities. The specification is built with this Java code C# Hl7.Fhir.R4 / Hl7.Fhir.STU3 : Object models, Parsers/Serializers, Utilities, and a Client. Source code on GitHub at https://github.com/FirelyTeam/firely-net-sdk Pascal FhirServer : Object models, Parsers/Serializers, Validator, Utilities, Client, and the FHIR Reference server. Requires Delphi (Unicode versions) XML XML Tools : Document Rendering Stylesheet, supplementary implementation schemas and transforms Javascript See the HL7 wiki for Javascript libraries (Clients and Utilities for both servers and clients) Python Python SMART can be found on FHIR client : Object Model, Client and Utilities Swift Swift-FHIR HL7's Confluence site here icon : Object Model, Client and Utilities .

Implementation Note: These The reference implementations and servers are provided for implementer interest and assistance. While they may be used (and are) in production systems, HL7 and their various contributors accept no liability for their use. Note that these reference implementations are provided to assist to implementers to adopt the specification, and some are maintained by the FHIR project team, but are not part of the specification, and implementations are not required to conform to these, the reference implementations, nor are they subject to the formal standards process.

Full blown open source implementations for FHIR, some of which use these reference implementations, are listed on HL7 Confluence icon .

It is not necessary to use these particular implementations in order to be conformant. Any other approach may be used, including code generated from the schemas.
