Summarytrue
Comments

The subject of a data requirement is critical, as the data being specified is determined with respect to a particular subject. This corresponds roughly to the notion of a Compartment in that it limits what data is available based on its relationship to the subject. In CQL, this corresponds to the context declaration.

DataRequirement.mustSupport
Element IdDataRequirement.mustSupport
Definition

Indicates that specific elements of the type are referenced by the knowledge module and must be supported by the consumer in order to obtain an effective evaluation. This does not mean that a value is required for this element, only that the consuming system must understand the element and be able to provide values for it if they are available.

The value of mustSupport SHALL be a FHIRPath resolveable on the type of the DataRequirement. The path SHALL consist only of identifiers, constant indexers, and .resolve() (see the Simple FHIRPath Profile for full details).

Standards StatusThis element has a standards status of "Trial Use"
Element IdTriggerDefinition
Definition

A description of a triggering event. Triggering events can be named events, data events, or periodic, as determined by the type element.

Cardinality0..*
TypeElement
Summarytrue
Comments

If an event is a named-event, it means the event is completely pre-coordinated, and no other information can be specified for the event. If the event is one of the data- events, the data and condition elements specify the triggering criteria. The data element specifies the structured component, and the condition element provides additional optional refinement of that structured component. If the event is periodic, the timing element defines when the event is triggered. For both data- and periodic events, a name can be provided as a shorthand for the formal semantics provided by the other elements.

Cardinality0..1
TypeExpression
Requirements

Need to be able to formally describe the triggering criteria.

Summarytrue
Comments

This element can be only be specified for data type triggers and provides additional semantics for the trigger. The context available within the condition is based on the type of data event. For all events, the current resource will be available as context. In addition, for modification events, the previous resource will also be available. The expression may be inlined, or may be a simple absolute URI, which is a reference to a named expression within a logic library referenced by a library element or extension within the containing resource. If the expression is a FHIR Path expression, it evaluates in the context of a resource of one of the type identified in the data requirement, and may also refer to the variable %previous for delta comparisons on events of type data-changed, data-modified, and data-deleted which will always have the same type.
