How to: Translating language for multiple products/categories

Question

My current setup is like this (new install).

• main website
  • main website store
    • store view English
    • store view German

Using Magmi, I know how to create my category structure (on the fly) - and how to add my 100 products to the default category.

However, how should I handle it, when I want to have my same product catalog translated into German when that store view is selected?

From what I can tell, this is a two part problem.

1. How to handle from a Magento perspective:

   • Do I create two unique root categories for each language and duplicate the product list into each?
   • Do I have one list/category, by somehow manage the translation for name and description somewhere else?? ..... I'm a bit lost!

2. How to then manage that with Magmi... but maybe its better to resolve point 1 first. Hopefully it becomes clear and simple to me by then :)

Thank you!
