Multilingual set up of the Data Portal¶

1) Install the following modules (see #5913)

 Multilingual                         Language Icons (languageicons)       
 Multilingual - Internationalization  Internationalization (i18n)         
 Multilingual - Internationalization  Menu translation (i18n_menu)        
 Multilingual - Internationalization  Multilingual content (i18n_node)    
 Multilingual - Internationalization  String translation (i18n_string)    
 Multilingual - Internationalization  Translation sets (i18n_translation) 
 Multilingual - Internationalization  Variable translation (i18n_variable)

Notes on automatic installation of translations:

The translations can be named as $langcode.po or with names ending with $langcode.po.

Translations are only automatically imported during the installation of the module for
all the languages already set up on the site,
see https://api.drupal.org/api/drupal/includes!locale.inc/function/locale_batch_by_component/8.x for details.

If the module is already enabled you need to disable and re-enable it. Alternatively you can use the following drush command:

drush php-eval "locale_system_update(array('yourmodule_name'));drush_backend_batch_process();"
