This Code system is used in the following value sets:

4.2.12.203.1 Content

4.2.12.203.2 ReferenceHandlingPolicy

A set of flags that defines how references are supported.

This code system http://hl7.org/fhir/reference-handling-policy defines the following codes:

CodeDisplayDefinition
literal Literal ReferencesThe server supports and populates Literal references where they are known (this code does not guarantee that all references are literal; see 'enforced')
logical Logical ReferencesThe server allows logical references
resolves Resolves ReferencesThe server will attempt to resolve logical references to literal references (if resolution fails, the server may still accept resources; see logical)
enforced Reference Integrity EnforcedThe 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 OnlyThe server does not support references that point to other servers
