ValueSet

Expansion performed internally based on codesystem Version Algorithm v6.0.0-ballot3 (CodeSystem)

This value set contains 8 concepts

SystemCodeDisplayDefinition
http://hl7.org/fhir/version-algorithm   semver SemVer

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

http://hl7.org/fhir/version-algorithm   integer Integer

Versions are integers and ordered numerically

http://hl7.org/fhir/version-algorithm   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)

http://hl7.org/fhir/version-algorithm   date Date

Versions are expressed as an ISO date/time syntax (including syntaxes with only portions of a date) in the general format of YYYY-MM-DD (with or without separators). Inclusion of the time portion is optional.

http://hl7.org/fhir/version-algorithm   natural Natural

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

http://hl7.org/fhir/version-algorithm   major-minor Major/Minor

Similar to semver, but having only two components - i.e. a major and minor (integer) version number separated by a '.'. The specific nature of what constitutes a major vs. minor increment is locally defined.

http://hl7.org/fhir/version-algorithm   sct-url SNOMED-CT URL

Versions are expressed according to the SNOMED URL scheme. See the Versions icon topic for more details.

http://hl7.org/fhir/version-algorithm   us-date US Date

Versions are expressed as an US date format, i.e. MMDDYYYY (with or without separators).

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
Comments Additional notes about how to use the code
