I'm discussing here and there a trick to assign good keywords to items in a *consistent way* into any wiki project. The advantage could be, that they could be searched *by presently running search engine*. I'm working into a couple of wikisource projects, but I presume that the need of a comfortable keyword search is much mandatory into Commons.
Here the links to my contributions: http://meta.wikimedia.org/wiki/Meta:Babel#Keyword_search http://en.wikisource.org/wiki/User_talk:Jayvdb#Thoughts_about_keywords
I's like to know your opinion about.
