Modern RESTful healthcare interoperability standard. JSON-based, web-native.

Why it matters to buyers: The strategic direction of healthcare interop. CMS + ONC push FHIR adoption.

Why it matters to engineers: Not yet dominant for imaging — DICOMweb + DICOM WADO-RS / QIDO-RS / STOW-RS + FHIR ImagingStudy is the bridge pattern.
