Following numerous discussions and after input from many people, we are happy to present the new version of the proposal that would lead to Wikidata supporting structured data for the Wiktionaries.
http://www.wikidata.org/wiki/Wikidata:Wiktionary
I am very thankful to all those that provided input, and am also happy to be able to send this out before Wikimania, and thus potentially have a good discussion there. But obviously everyone feel free to chime in beyond that.
I would be glad if I could again ask the community to spread the word to the Wiktionary communities, in order to gain as much feedback from them as possible, and hopefully support.
Cheers, Denny
