Welcome, Christian! Thanks for joining the list - would you mind forwarding this note to talk-fr?
Those threads on talk-fr look like exactly what we have in mind for Historical OSM: http://lists.openstreetmap.org/pipermail/talk-fr/2012-December/052738.html http://forum.openstreetmap.fr/viewtopic.php?f=2&t=376&start=0 http://forum.openstreetmap.fr/viewtopic.php?f=2&t=395&start=0 And, the questions you ask about tagging are at the core of what we are trying to figure out, which is: how should we do this? Welcome aboard!
