Nexus EMR profile for the Observation resource, based on CA-Core. Represents measurements, tests, and simple assertions originating from source EMRs for aggregation.
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.
