This Code system is used in the following value sets:

  • ValueSet: Version Algorithm (Indicates the mechanism used to compare versions to determine which is more current.)

Indicates the mechanism used to compare versions to determine which is more current.

This case-sensitive code system http://hl7.org/fhir/version-algorithm defines the following codes:

semver SemVer

Uses the semantic versioning scheme as defined in semver.org icon.

btn btn
integer Integer

Versions are integers and ordered numerically

btn btn
alpha Alphabetical

Simple alphabetic sort on a case-insensitive and accent-insensitive basis. (Sorting of different cases or accented versions of a character is indeterminate)

btn btn
date Date

Versions are expressed as an ISO date/time syntax (including syntaxes with only portions of a date)

btn btn
natural Natural

Sorted according to the algorithm defined here: naturalordersort.org icon

btn btn

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. 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
