2.27 DomainResource Resource

http://www.hl7.org/Special/committees/fiwg/index.cfmMaturity Level: N Normative (from v4.0.0) Compartments: Not linked to any defined compartments

A domain resource is a resource that:

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

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.

dom-6Guideline (base)A resource should have narrative for robust managementtext.div.exists()
This is (only) a best practice guideline because:

When a resource has no narrative, only systems that fully understand the data can display the resource to a human safely. Including a human readable representation in the resource makes for a much more robust eco-system and cheaper handling of resources by intermediary systems. Some ecosystems restrict distribution of resources to only those systems that do fully understand the resources, and as a consequence implementers may believe that the narrative is superfluous. However experience shows that such eco-systems often open up to new participants over time.

To search for extensions, define a SearchParameter 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.

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