Resource Note Extension

Canonical	../StructureDefinition/nexus-emr-resource-note
Status	draft · 1.26.0
Base	Extension (constraint)
Context	DomainResource (element)
Source	FSH · JSON

An attributed note recorded on a resource with no note element of its own, such as the comment thread on a DocumentReference. Each repeat is one note in the Task Note turn shape -- author and time required, markdown text, machine authors as identifier-only logical references -- so every thread in the EMR reads and validates identically. The thread is append-only and readers order it by the value's time, oldest first. Where a resource defines a native note element, that element is the home and this extension is not used.

Invariants

Every rule in force on a conforming instance. This profile rows are stated here; inherited rows come from the base resource and are listed so that a constraint named on an element is findable. Invariant keys elsewhere on this page link into this table.
