## ⁠2.9. Input Methods

### ⁠2.9.1. Introduction

It is a nice feature for a software center to allows users the installation of additional input methods. This meta-info specification describes how metadata about input methods should be structured.
Software components providing an input method can ship one or more files in `/usr/share/metainfo/%{id}.metainfo.xml`.
Input method metadata files can – just like all other metainfo files – be translated. See the section about translation for more information.

### ⁠2.9.2. Example file

The input method meta-info file should look like this:

    ​
    ​<?xml version="1.0" encoding="UTF-8"?>
    ​<component type="inputmethod">
    ​  <id>com.github.ibus.mathwriter-ibus.db</id>
    ​  <metadata_license>FSFAP</metadata_license>
    ​  <name>Mathwriter</name>
    ​  <summary>Math symbols input method</summary>
    ​  <description>
    ​    <p>
    ​      The input method is designed for entering mathematical symbols.
    ​    </p>
    ​    <p>
    ​      Input methods are typing systems allowing users to input complex languages.
    ​      They are necessary because these contain too many characters to simply be laid
    ​      out on a traditional keyboard.
    ​    </p>
    ​  </description>

    ​</component>

### ⁠2.9.3. File specification

Note that the XML root must have the `type` property set to `inputmethod`. This clearly identifies this metainfo document as describing an input method instead of a generic software component.

⁠<id/>
  For input methods, the `%{id}` should follow the standard reverse-domain-name scheme. For the product name part, it is recommended to take the database filename of the input method.
<metadata_license/>
  The `<metadata_license/>` tag is required. See Section 2.1, “Generic Component” for a description of this tag.
<name/>
  Set a name for your input method.
<summary/>
  A short description of the input method described in this metainfo file.
<description/>
  Add a long description of the input method.
  Do not assume the format is HTML. Only paragraph, ordered list and unordered list are supported at this time.
<screenshots/>
  A screenshot may be included, showing the input method in use in an application.
  Refer to <screenshots/> for a detailed description of this tag.
<url/>
  This is a recommended tag for links of type `homepage`. Links of type `homepage` should be a link to the upstream homepage for the application. See See <url/> for a description of this tag.
<provides/>
  This tag is described for generic components at <provides/> in detail.
  You can add one or more children of type `<library/>` in case you publish some additional shared libraries. If not, and there are no public binaries involved, you may omit the `provides` tag for input methods.

For a component of type `inputmethod`, the following tags are required and must be present: <id/>, <name/>, <summary/>, <metadata_license/>.
