In July 2011, Achal Prabhala start an oral citation research "helping overcome a lack of published material in emerging languages on Wikipedia". But unfortunately, no more of this kind of initiative seams created and oral knowledge don't still really have places in Wikimeida projects. So, the question is still there : what can we do to introduce knowledge from oral culture into the Wikimedia movement?
