2.0.1-sd - release
Clinical Document Architecture, published by Health Level 7. This guide is not an authorized publication; it is the continuous build for version 2.0.1-sd built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/CDA-core-sd/ and changes regularly. See the Directory of published versions
| Official URL: http://hl7.org/cda/stds/core/StructureDefinition/ObservationMedia | Version: 2.0.1-sd | |||
| Active as of 2025-10-02 | Computable Name: ObservationMedia | |||
A derivative of the RIM Observation class that represents multimedia that is logically part of the current document. This class is only for multimedia that is logically part of the attested content of the document. Rendering a referenced ObservationMedia requires a software tool that recognizes the particular MIME media type.
An XML attribute "ID" of type XML ID, is added to ObservationMedia within the CDA Schema. This attribute serves as the target of a renderMultiMedia reference (see renderMultiMedia). All values of attributes of type XML ID must be unique within the document (per the W3C XML specification).
The distinction between ObservationMedia and ExternalObservation is that ObservationMedia entries are part of the attested content of the document whereas ExternalObservations are not. For instance, when a clinician draws a picture as part of a progress note, that picture is represented as a CDA ObservationMedia. If that clinician is also describing a finding seen on a chest-x-ray, the referenced chest-x-ray is represented as a CDA ExternalObservation.
