## ⁠2.12. Localization

### ⁠2.12.1. Localization

The `localization` component type describes language packs for individual software components or groups of software components. A language pack includes anything necessary to localize a software component for a specific language and/or country. This is usually translations, but may also be translated media content, currency information and other things. A `localization` component `extends` one or multiple other components and defines the languages it provides via its `languages` tag.
Language packs can ship one or more metainfo files as `/usr/share/metainfo/%{id}.metainfo.xml`.

### ⁠2.12.2. Example file

A localization metainfo file can look like this:

    ​
    ​<?xml version="1.0" encoding="UTF-8"?>
    ​<component type="localization">
    ​  <id>org.kde.l10n.de</id>
    ​  <name>KDE German Language</name>
    ​  <summary>German localization for the KDE desktop and apps</summary>
    ​
    ​  <extends>org.kde.plasmashell</extends>
    ​  <extends>org.kde.gwenview.desktop</extends>
    ​  <extends>org.kde.dolphin.desktop</extends>
    ​  ...
    ​
    ​  <url type="homepage">http://i18n.kde.org/team-infos.php?teamcode=de</url>
    ​  <metadata_license>FSFAP</metadata_license>
    ​
    ​  <developer_name>The KDE German L10N team</developer_name>
    ​
    ​  <languages>
    ​    <lang>de_DE</lang>
    ​    <lang percentage="96">de_AT</lang>
    ​    <lang percentage="100">de</lang>
    ​    ...
    ​  </languages>
    ​</component>

### ⁠2.12.3. File specification

Note that the XML root must have the `type` property set to `localization`. This clearly identifies this metainfo document as describing a language pack.

⁠<id/>
  For localizations, the value of the `<id/>` tag must follow the reverse-DNS scheme as described for generic components. Ideally, the name of the component this language pack is for should be suffixed with `.l10n.%{lang}`, where `%{lang}` is the language code of the language pack.
  For example, if your applications component-id is `org.gimp.gimp` the ID of the German language pack for GIMP should be `org.gimp.gimp.l10n.de`.
⁠<extends/>
  The `extends` tags contain all the components this language pack can be used with.
⁠<languages/>
  This tag gives information about the locale a localization component provides support for.
  The tag is allowed to only occur once per component, and contains multiple `<lang/>` child nodes, which have a language code as value. Each `<lang/>` node may have a `percentage` property, which describes the percentage value to which a component has been translated.
  Tag example:

      ​<languages>
      ​  <lang>de_DE</lang>
      ​  <lang percentage="94">de_AT</lang>
      ​</languages>

For a component of type `localization`, the following tags are required and must be present for a valid document: <id/>, <name/>, <summary/>, <metadata_license/>, <extends/>, <languages/>.
