US Core Implementation Guide
8.0.0-ballot - Ballot United States of America flag

US Core Implementation Guide, published by HL7 International / Cross-Group Projects. This guide is not an authorized publication; it is the continuous build for version 8.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/US-Core/ and changes regularly. See the Directory of published versions

ValueSet: Language codes with language and optionally a region modifier

Official URL: http://hl7.org/fhir/us/core/ValueSet/simple-language Version: 8.0.0-ballot
Standards status: Trial-use Maturity Level: 3 Computable Name: LanguageCodesWithLanguageAndOptionallyARegionModifier
Other Identifiers: OID:2.16.840.1.113883.4.642.40.2.48.4

Copyright/Legal: ISO Maintains the copyright on the country codes and controls it's use carefully. For further details, see the ISO 3166 Home Page

This value set includes codes from BCP-47. This value set matches the ONC 2015 Edition LanguageCommunication data element value set within C-CDA to use a 2 character language code if one exists, and a 3 character code if a 2 character code does not exist. It points back to RFC 5646, however only the language codes are required, all other elements are optional.

References

Changes since version 7.0.0:

  • The logical definition of the value set has changed

    • The publication tooling cannot expand the language value set because they are based on a grammar. To aid in the reader's understanding, sample codes are shown below:

    Examples of 2-character codes for common languages

    ISO 639-1 Code English name of Language
    en English
    es Spanish
    zh Chinese
    fr French
    tl Tagalog
    vi Vietnamese

    Examples of 3-character code for languages where a 2-character code does not exist

    ISO 639-2 Code English name of Language
    yue Cantonese
    chn Chinook jargon
    cho Choctaw
    chp Chipewyan
    chr Cherokee

    Logical Definition (CLD)

    Generated Narrative: ValueSet simple-language

    • Include codes fromurn:ietf:bcp:47 where icon Changed:ext-lang doesn't exist, icon Changed:script doesn't exist, icon Changed:variant doesn't exist, icon Changed:extension doesn't exist and icon Changed:private-use doesn't exist

     

    Expansion

    This value set cannot be expanded because of the way it is defined - it has an infinite number of members

    Explanation of the columns that may appear on this page:

    Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
    System 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)
    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
