FHIR Definitions	All the value sets, profiles, etc.defined as part of the FHIR specification, and the included implementation guides: XML JSON Forge: Special version of definitions for Forge (temporary) These is the master set of definitions that should be the first choice whenever generating any implementation artefacts. 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	Examples - all the example resources in XML format Validation Schemas (includes support schemas, resource schemas, modular & combined schemas, and Schematrons) Code Generation Schemas (See notes about code-generation schemas)
JSON	Examples - all the example resources in JSON format JSON Schemas (includes both modular and combined schema)
RDF	Examples - all the example resources in Turtle format ShEx Schemas - ShEx definitions for validating RDF resources Definitions - the formal definitions that define the predicates and classes used in the RDF format (not up to date)
FHIR Specification	The whole specification so that you can host your own local copy (does not include the downloads)
Implementation Tools
Validator	The official FHIR validator - a Java jar file that can be used to validate resources. See Validation Tools for further information
IG Publisher	The Implementation Guide Publishing Tool (see IG Publishing documentation ) (note: use the current build version, and set the version in your control file)
Translation File	Translations of common FHIR names and messages into multiple languages (see wiki for instructions on how to add to this)
Icon Pack	The FHIR Icon at various resolutions. The FHIR icon is an HL7 trademark, and written permission is required to make use of this icon. See the FHIR Trademark policy and the application forms for event or product use.
Reference Implementations
There are many open source reference implementations available to help implementers. Here are a 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 : Object models, Parsers/Serialisers, Utilities, and a Client. Source code on GitHub at http://github.com/ewoutkramer/fhir-net-api
Pascal	FhirServer : Object models, Parsers/Serialisers, Validator, Utilities, Client, and the FHIR Reference server. Requires Delphi (unicode versions)
XML	XML Tools: Document Rendering Stylesheet, supplementary implementation schemas and transforms
Javascript	FHIR.js : Javascript Client and Utilities
Swift	Swift-FHIR : Object Model, Client and Utilities

Note: These reference implementations are provided for implementer interest and assistance. While they may be used (and are) in production system, 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, 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 the HL7 wiki .

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.
