CMS/Wiki focused on content translations?

Question

CMS

You need to launch the help portal and user documentation. Each page should be available in multiple languages. Are there any CMS or wikis with built-in translation support? I want these features:

• Paragraph translation. This means that when translating, each paragraph is a separate block. At the same time, the system remembers which block of the source text corresponds to the block of the translated text and allows you to make changes in a convenient form after;
  
• Warnings that translated content is out of date - after there have been changes in the corresponding paragraph in another language;
  
• Convenient switching between languages ​​(eg "this page is accessible in the following other languages: ...");
  
• The ability to choose whether to show a paragraph on the page for which there is no translation in the original language.
  

I found a plugin for MediaWiki that has at least some of the above. Are there other systems natively supporting translation and synchronization features?

Answer 1

For Drupal, there are modules that implement the specified functionality.

Answer 2

Three years ago, this was not the case. I had to finish MediaWIKI on my own... Apparently, there are no systems that fully satisfy your requirements. You can only blind from the same MediaWIKI with the help of several extensions. At a minimum, versioning of individual paragraphs is possible, as well as multilingualism.

Answer 3

So far, only www.anwiki.com/ has been found. This wiki seems to fulfill all the requirements given in the question.
But there's a problem. Yes, this wiki does a really good job of keeping translations up to date. But all the other functions are implemented extremely poorly :( And the look of this wiki is very, very simple. If you use it, you will need to finish a lot of things manually.
