Multilingual Drupal

Though Drupal core has some basic multilingual support built in, it still needs some help -contributed modules- for being able to build a fully featured multilingual site. I've been working on building better multilingual support into Drupal for some years and still keep maintaining Internationalization module to translate what's left by Drupal core.
Currently we are working on the D8MI initiative to make Drupal 8 really fully multilingual.

As it seems a brand new Drupal localization site is coming to life any of these days, we still need to work out some issues like how the translations will be packaged to support all of our existing deployment models and maybe some new ones. We've been thinking and talking for some time about it...
