Optional Extension Element - found in all resources.

ShortR5: Triggering observation(s) (new)Optional Extensions Element
Comments

Element Observation.triggeredBy has a context of Observation based on following the parent source element upwards and mapping to Observation. Element Observation.triggeredBy has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).

Definition

An Extension


May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

          Element Observation.triggeredBy.type is part of an existing definition because parent element Observation.triggeredBy requires a cross-version extension. Element Observation.triggeredBy.type has a context of Observation based on following the parent source element upwards and mapping to Observation. Element Observation.triggeredBy.type has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).

          Definition

          May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

          There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
