Handling multilingual documentation (for multiple apps) -

we have (web)apps used in multiple countries , therefore apps/documentation translated languages being used.

we're starting have problems keeping documentation date in languages.

normal scenario:

• change made in app
• changes made eng documentation
• same changes language-specific screenshots should done other languages (and different people responsible of different translations)

we never seem in status, our documentation date.

currently our documentation handled powerpoints (i know!!!). find better solution. have tested atlassians confluence, not seem meet our need in multilingual-part.

we should able that:

• this english documentation
  • then should able that:
    • a missing norwegian documentation
    • a's norwegian documentation has not been updated, though english on has changes.

english master , should have date documentation in - if missing part b norwegian, english shown.

i rid of old powerpoints (which have thousands of pages , versions)... :) think i'm looking wiki-type-solution, there should way inform responsible persons when changes made master language (and therefore changes needed other languages).

if decide author documentation in non-binary , non-proprietary format such xml, keeping under source control (such svn) accurate , reliable way keep track of changes. example, if store english documentation in folder called "english" , have parallel folders other languages, changes "english" folder become to-do list other languages.

one of tools possible author xml documentation in wysiwyg interface help&manual (by way, not affiliated them in way).
