1.19.5 Resource DomainResource - Detailed Descriptions

Detailed Descriptions for the elements in the DomainResource Resource.

DomainResource
Definition	A resource that includes narrative, extensions, and contained resources.
Control	1..1
Invariants	Defined on this element dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (expression: contained.text.empty(), xpath: not(parent::f:contained and f:text)) dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (expression: contained.contained.empty(), xpath: not(parent::f:contained and f:contained)) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource (expression: contained.select(('#'+id in $context.descendents().reference).not()).empty(), xpath: not(exists(for $id in f:contained//@id return $id[not(ancestor::f:contained/parent::/descendant::f:reference/@value=concat('#', $id))]))) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (expression: contained.meta.versionId.empty() and contained.meta.lastUpdated.empty(), xpath: not(exists(f:contained//f:meta/f:versionId)) and not(exists(f:contained//f:meta/f:lastUpdated)))
DomainResource.text
Definition	A human-readable narrative that contains a summary of the resource, and may be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Control	0..1
Type	Narrative
Alternate Names	narrative; html; xhtml; display
Comments	Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative.
Invariants	Affect this element dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (expression: contained.text.empty(), xpath: not(parent::f:contained and f:text))
DomainResource.contained
Definition	These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
Control	0..*
Type	Resource
Alternate Names	inline resources; anonymous resources; contained resources
Comments	This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again.
DomainResource.extension
Definition	May be used to represent additional information that is not part of the basic definition of the resource. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Control	0..*
Type	Extension
Alternate Names	extensions; user content
Comments	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.
DomainResource.modifierExtension
Definition	May be used to represent additional information that is not part of the basic definition of the resource, and that modifies the understanding of the element that contains it. Usually modifier elements provide negation or qualification. In order 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 is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.
Control	0..*
Type	Extension
Is Modifier	true
Alternate Names	extensions; user content
Comments	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.
