Normative Candidate Note: This page is candidate normative content for R4 in the Infrastructure Package. Once normative, it will lose it's Maturity Level, and breaking changes will no longer be made.

2.26.1 Scope and Usage

A domain resource is an resource that:

As an abstract resource, this resource is never created directly; instead, one of its descendent resources (see List of Resources) is created.

2.26.2 Boundaries and Relationships

This resource extends the base resource. All of the listed Resources except Bundle, Parameters and Binary extend this resource.

DomainResource (Resource)A human-readable narrative that contains a summary of the resource and can 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 safetytext : Narrative [0..1]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 scopecontained : Resource [0..*]May be used to represent additional information that is not part of the basic definition of the resource. 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 extensionextension : Extension [0..*]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. 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.

2.26.3.1 Constraints

  • dom-1: If the resource is contained in another resource, it SHALL NOT contain any narrative (expression : contained.text.empty())
  • dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (expression : contained.contained.empty())
  • dom-3: 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 (expression : contained.all(('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists()))
  • 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())

2.26.4 Searching Extensions

To search for extensions, define a search parameter for the extension. All other search parameters are named aliases for existing content in the resource. In some cases, though not all, the search parameter name is the same as the element that it searches, but this is not required. Searching for extensions is the same - define a name that identifies the value extension by its URL, and then searches can filter based on the value of the extension.

2.26.5 Search Parameters

Common search parameters defined by this resource. See Searching for more information about searching in REST, messaging, and services.
