Constraints

Id	Grade	Path(s)	Details	Requirements
dom-2	error	Observation	If the resource is contained in another resource, it SHALL NOT contain nested Resources : contained.contained.empty()
dom-3	error	Observation	If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource : contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()
dom-4	error	Observation	If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated : contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()
dom-5	error	Observation	If a resource is contained in another resource, it SHALL NOT have a security label : contained.meta.security.empty()
dom-6	best practice	Observation	A resource should have narrative for robust management : text.`div`.exists()
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
ext-1	error	**ALL** extensions	Must have either extensions or value[x], not both : extension.exists() != value.exists()
obs-3	error	Observation.referenceRange	Must have at least a low or a high or text : low.exists() or high.exists() or text.exists()
obs-6	error	Observation	dataAbsentReason SHALL only be present if Observation.value[x] is not present : dataAbsentReason.empty() or value.empty()
obs-7	error	Observation	If Observation.code is the same as an Observation.component.code then the value element associated with the code SHALL NOT be present : value.empty() or component.code.where(coding.intersect(%resource.code.coding).exists()).empty()
vs-1	error	Observation.effective[x]	if Observation.effective[x] is dateTime and has a value then that value shall be precise to the day : $this is dateTime implies $this.toString().length() >= 10
vs-2	error	Observation	If there is no component or hasMember element then either a value[x] or a data absent reason must be present. : (component.empty() and hasMember.empty()) implies (dataAbsentReason.exists() or value.exists())
vs-3	error	Observation.component, Observation.component:FlowRate, Observation.component:Concentration	If there is no a value a data absent reason must be present : value.exists() or dataAbsentReason.exists()

Summary

Mandatory: 2 elements(12 nested mandatory elements)
Must-Support: 20 elements
Fixed: 6 elements

Structures

This structure refers to these other structures:

• TW Core CarePlan (https://twcore.mohw.gov.tw/ig/twcore/StructureDefinition/CarePlan-twcore)
• TW Core MedicationRequest (https://twcore.mohw.gov.tw/ig/twcore/StructureDefinition/MedicationRequest-twcore)

• TW Coding (https://twcore.mohw.gov.tw/ig/twcore/StructureDefinition/Coding-tw)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Observation.code.coding
• The element 1 is sliced based on the value of Observation.value[x]
• The element 1 is sliced based on the value of Observation.component
• The element 1 is sliced based on the value of Observation.component.value[x]
