The German language version of the online encyclopaedia will restrict instant editing to allow "trusted editors" to look over the content before it appears online.
The changes will come into effect later this year, and could be applied to the English language version of Wikipedia if feedback from users is positive.

Griffith cited several worrying examples, including the CIA editing a page on the 2003 invasion of Iraq to highlight the "speculative" nature of civilian casualty figures.
Sony, meanwhile, was caught editing information about Microsoft's upcoming Halo 3 game.
