+To set the `og:locale` property:
+
+```php
+seo()->locale('de_DE');

+Expected format is `language_TERRITORY`.

 ### Modifiers
 
 You may want to modify certain values before they get inserted into the template. For example, you may want to suffix the meta `<title>` with `| ArchTech` when it has a non-default value.
