CodeSystem: ReferenceHandlingPolicy

Official URL: http://hl7.org/fhir/reference-handling-policy Version: 3.0.2
Standards status: Trial-use Maturity Level: 3 Computable Name: ReferenceHandlingPolicy

A set of flags that defines how references are supported.

This Code system is referenced in the content logical definition of the following value sets:

  • This CodeSystem is not used here; it may be used elsewhere (e.g. specifications and/or implementations that use this content)

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

CodeDisplayDefinition
literal Literal References The server supports and populates Literal references where they are known (this code does not guarantee that all references are literal; see 'enforced')
logical Logical References The server allows logical references
resolves Resolves References The server will attempt to resolve logical references to literal references (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
