Tiki handles an unilingual website very well.
Goal: To become:
1- a strong tool for multilingual sites (non-parallel and parallel) using version control and document workflow & roles
And then:
2- an open source Translation Management System (TMS) using the Translation Memory eXchange open standard.
Tiki could then easily handle multilingual documentation.
Why do we need all this? Please see the video
