Formal Definition (as a OperationDefinition).

URL: [base]/$closure

This is not an idempotent operation

In Parameters:
Name Scope Cardinality Type Binding Profile Documentation
name 1..1 string

The name that defines the particular context for the subsumption based closure table

concept 0..* Coding

Concepts to add to the closure table

version 0..1 string

A request to resynchronise - request to send all new entries since the nominated version was sent by the server

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

A list of new entries (code / system --> code/system) that the client should add to its closure table. The only kind of entry mapping relationships that can be returned are equivalent, source-is-broader-than-target and source-is-narrower-than-target.

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
