4.4.1.534.2 Expansion

This expansion generated 20 Aug 2020

This value set contains 5 concepts

Expansion based on ReferenceHandlingPolicy v4.5.0 (CodeSystem)

All codes from system http://hl7.org/fhir/reference-handling-policy

Code	Display	Definition
literal	Literal References	The server supports and populates Literal references (i.e. using Reference.reference) where they are known (this code does not guarantee that all references are literal; see 'enforced').
logical	Logical References	The server allows logical references (i.e. using Reference.identifier).
resolves	Resolves References	The server will attempt to resolve logical references to literal references - i.e. converting Reference.identifier to Reference.reference (if resolution fails, the server may still accept resources; see logical).
enforced	Reference Integrity Enforced	The server enforces that references have integrity - e.g. it ensures that references can always be resolved. This is typically the case for clinical record systems, but often not the case for middleware/proxy systems.
local	Local References Only	The server does not support references that point to other servers.

Explanation of the columns that may appear on this page:

Lvl

A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')

Display

The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application

Definition

An explanation of the meaning of the concept
