## Service type description file format

Services types for libaccounts-glib providers are described with a simple XML file. An example for a hypothetical `CoolProvider` chat service is shown below:

Example 7. Service type description for e-mail

    <?xml version="1.0" encoding="UTF-8"?>
    <service-type id="e-mail">
      <name>Electronic mail</name>
      <description>Send mail without harming snails</description>
      <icon>email</icon>
      <translations>email</translations>
      <tags>
        <tag>e-mail</tag>
        <tag>messaging</tag>
      </tags>

    </service-type>

The example service type description describes a service type called `e-mail`, indicated by the `id` attribute on the `service-type` root element. The `name` element contains a human-readable version of the service type name. The `description` is a string that describes the service type in general. The `icon` element specifies a themed icon to represent the service type. The `translations` element is used to indicate the gettext translation domain for the name and description elements, to be used by applications when showing those elements in a UI. The `tags` element is a container of `tag` elements, which are used to describe the service type in abstract terms.

### Installation

Service type description filenames should end in `.service-type` and be installed to `${prefix}/share/accounts/service_types`, which normally expands to `/usr/share/accounts/service_types`. The path can be queried with pkg-config by checking the `servicetypefilesdir` variable of the libaccounts-glib pkg-config file, for example:

    pkg-config --variable=servicetypefilesdir libaccounts-glib
