HL7 is an ANSI Accredited Standards Development Organization. As such, ANSI reviews HL7 processes both in general, and also specifically with regard to each standard. While ANSI certified that portions of this release of

FHIR (Release 4) met its requirements for development of a formal standard, this version (R4B) is a trial use version, and ANSI Release 5 will not be asked to certify R4B. HL7 has still treated these portions of the specifications as Normative, and no breaking changes have been made submitted to the specifications. Given that many areas of the FHIR specification are still undergoing Trial Use by the HL7 Community, and hence are not ready ANSI for balloting consideration as a formal ANSI standard, and in order to manage the processes around the ballot process, four specific portions of this specification are considered as Normative Specifications: Infrastructure The core framework on which FHIR solutions depend (Abstract base types, data types, formats, standard. None of the RESTful API, and new content in R5 is considered Normative, and typing rules) Conformance The terminology infrastructure and will be subject for futher review during the base resources that define FHIR implementations review and ballot process for Release 6. Note that represent how the specification, and conformance to it, is defined Patient The Patient resource and related content Observation The Observation resource and related content Given that the Normative parts of the standard are still a subset of what implementers need to use, implementers are generally focusing on conforming to FHIR R4 as a whole rather than the formal standards. Future versions of this specification was normative for Release 4 remains in effect normative, and will extend be treated accordingly during the coverage of format standards. R6 process.
