Expansion based on Capability Features v4.6.0 (CodeSystem)

All codes in this table are from the system

trueValue is true
falseValue is false
no-versionNo VersionId SupportVersionId meta-property is not supported (server) or used (client).
versionedVersionedVersionId meta-property is supported (server) or used (client).
versioned-updateVersionId tracked fullyVersionId must be correct for updates (server) or will be specified (If-match header) for updates (client).
not-supportedNot SupportedNo support for conditional reads.
modified-sinceIf-Modified-SinceConditional reads are supported, but only with the If-Modified-Since HTTP Header.
not-matchIf-None-MatchConditional reads are supported, but only with the If-None-Match HTTP Header.
full-supportFull SupportConditional reads are supported, with both If-Modified-Since and If-None-Match HTTP Headers.
singleSingle Deletes SupportedConditional deletes are supported, but only single resources at a time.
multipleMultiple Deletes SupportedConditional deletes are supported, and multiple resources can be deleted in a single interaction.
literalLiteral ReferencesThe 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').
logicalLogical ReferencesThe server allows logical references (i.e. using Reference.identifier).
resolvesResolves ReferencesThe 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).
enforcedReference 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.
localLocal References OnlyThe server does not support references that point to other servers.

Explanation of the columns that may appear on this page:

LvlA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
