5.3.11.1 Operation $subset on CapabilityStatement

FHIR Infrastructure icon Work Group Maturity Level: 5Trial Use Compartments: N/A

This operation asks the server to return a subset of the CapabilityStatement resource - just the REST parts that relate to a set of nominated resources - the resources that the client is interested in.

The canonical URL for this operation definition is

 http://hl7.org/fhir/OperationDefinition/CapabilityStatement-subset

Formal Definition (as a OperationDefinition).

URL: [base]/CapabilityStatement/$subset

URL: [base]/CapabilityStatement/[id]/$subset

This is an idempotent operation

In Parameters:
Name Scope Cardinality Type Binding Profile Documentation
server type, system 0..1 uri

The canonical URL - use this if the subset is not invoked on an instance (or on the /metadata end-point)

resource 1..* code

A resource that the client would like to include in the return

Out Parameters:
Name Scope Cardinality Type Binding Profile Documentation
return 1..1 CapabilityStatement

The subsetted CapabilityStatement resource that is returned. This should be tagged with the SUBSETTED code

Note: as this is the only out parameter, it is a resource, and it has the name 'return', the result of this operation is returned directly as a resource
