FHIR DSTU2 is published

The FHIR team is pleased to announce that FHIR DSTU is now published at The 2nd DSTU is an extensive rewrite of all parts of the specification. Some of the highlights this version accomplishes:

  • Simplifies the RESTful API
  • Extends search and versioning significantly
  • Increases the power and reach of the conformance resources and tools
  • Defines a terminology service
  • Broadens functionality to cover new clinical, administrative and financial areas
  • Incorporates thousands of changes in existing areas in response to trial use

As part of publishing this version, we have invested heavily in the quality of the process and the specification, and the overall consistency is much improved. A full list of changes to the FHIR standard can be found at

In addition, DSTU2 is published along with several US-realm specific implementations developed in association with the ONC: DAF, SDC, and QICore.
