On the topic of multilingual coordination at large, I have often thought when adding interwiki links to pages that it would be nice to have a central, language-independent repository of cross-language links.
(Probably these issues have been raised before; sorry if I'm rehashing old points or raising them in the wrong place.)
I've seen essentially two problems as is: - links to new translations don't get added everywherewikipedia - erroneous cross-language links can persist even after being corrected somewhere
Robots can solve the first problem but not the second. An example of the second is 'Germanic languages'. There are not too many wikipedias that have any entry for this topic specifically. However, someone had linked a number of them to the equivalent for 'German language' in other wikipedias, probably not realizing the difference.
I don't see how a robot could solve this problem without semantic knowledge of the equivalents of 'Germanic language' in various languages.
