We could rewrite all our Author modules in Lua for authors, and put all our authors in Wikidata. That is probably the first thing we should do.
On fr.ws whe have http://fr.wikisource.org/wiki/Cat%C3%A9gorie:Pages_%C2%AB_Auteur_%C2%BB_sans... ; same cat on en.ws http://en.wikisource.org/wiki/Category:Author_pages_not_connected_to_Wikidat...
It is very useful to fill Wikidata !
