While uploading into IA books from an interesting Italian library (http://www.opal.unito.it) we are exploring anything useful to automatize upload and to collect into Internet Archive anu metadata useful to automatize IA->Commons->wikisource flow and IA metadata retrieval (both by python and by jQuery).
A new collection: opallibriantichi - collects recents uploads from http://www.opal.unito.it
and is used to tests and scripts debugging. I got admin privileges for this collection. Most of upload work is going on using itsource tool into Tool Labs at dev-login.
Please notify in that page (or its Talk page) existence of similar pages/projects/experiences here or there.
