Fast Healthcare Interoperability Resources is now normative, and the new edition brings thousands of other updates. Health Level Seven announced on Wednesday that a new version of its interoperability specification is now available.WHY IT MATTERSMany in the healthcare industry have been eagerly awaiting the fourth iteration of FHIR 4 because future changes will now be backward compatible.”Applications that implement the normative parts of R4 no longer risk being non-conformant to the standard,” said FHIR Product Director Grahame Grieve on the FHIR blog.Grieve also noted that in addition of the base platform several key piece of FHIR are also now normative, including the RESTful API, the XML and JSON formats, the terminology layer, the conformance framework as well as Patient and Observation resources.THE BIGGER TRENDFHIR and open APIs are widely considered to be critical to making health data more interoperable.
