Looking for an open source CMS with excellent internationalization and localization [closed]

Question

Can anyone suggest a CMS able to offer the following features:

• Free/open source
• Support for multiple languages (both frontend and backend)
• Support for translating content (i.e. an article can have 1+ translations)
• Support for different content types, namely pages, articles (timestamped, with comments) and image (galleries).
• Support for basic categorization (just a level of sections is sufficient)
• Support for media management (localizable image galleries)
• User friendly
• lightweight and fast
• PHP or Ruby based
• mature enough

Personally, I can only think of Drupal 6, but it's quite an overkill for what I want to do, and localization is not working 100%. I basically can live with anything which was built from the ground up with localization in mind.

Answer 1

After days of looking around and tryng out various demo site, SPIP seems to be the only proper solution to my problem. Any other idea?

Answer 2

Daisy was built from the ground-up with localization in mind.

In Daisy, each document can have one or more language variants, and Daisy tracks whether the source document and the translated variant are in-sync or not. This makes it very easy to manage change.

For example, I can ask Daisy 'Give me a list of documents for which either the Japanese translation doesn't exist, or it is not longer in sync with the original'. You can do this for any file type, including screenshots.

I think it hits all of your requirements except that it's built on the Java stack.

Answer 3

How about Joomla? I'm not sure if it fulfills all your requirements, but it's a suggestion nonetheless.

Answer 4

Probably under-kill, but WordPress with the qTranslate plugin works well for i18n of the admin interface plus the main content block of your page.
