| Official URL: https://fhir.onyxhealth.io/us/arex/StructureDefinition/arex-binary | Version: 0.1.0 | |||
| Draft as of 2026-08-12 | Computable Name: ARexBinary | |||
A retrievable content object served as raw octets. Binary is used in preference to any base64-in-JSON representation: retrieval with a non-FHIR Accept header returns the native bytes and native content type, with no encoding inflation. NOTE: Binary is not a DomainResource and cannot carry extensions; all ARex metadata for an object lives on its ARex Content Entry.
