Import translation file only for specific core module I am creating a multilingual D7 website. I am using core module locale and i18n contrib module. I am trying to import the localization files for a language.

I know that I can download the unified .po file for a language from https://localize.drupal.org and import it in the multilingual website from http://EXAMPLE.COM/admin/config/regional/translate/import.

Is there a way I can export from https://localize.drupal.org a .po file only for a specific core module (eg contact)? I can do this for a contrib module but not for a core module.

Thanks a lot.
Nope, you cannot. 

Translations are stored per project, not per module, and core is one project. Of course there is experimental Contact project on Drupal.org, but it's translation stays pretty empty as it's not needed.

Worse, in exported files (at least in my language) there is no metadata, no comments about modules these strings originated. So manually cutting this file to your needs would be pretty hard, too.
