Personally I have been using
aarddict for offline wikipedia content.
As already mentioned, stardict used to have wikipedia support, and I still have a copy of simple wiki in stardict format.
I opened it in goldendict, but it looks awful. So, I guess goldendict does not support maketypesequence=w.
Although, I remember that stardict itself did not have very good wikipedia support either. Also, the author of stardict had not managed to compile the largest wikipedias (en, fr, de) due to size limitations.
So, stardict format is pretty much a no-go.
