There's been some interest lately on this list in the use of W3C XForms for library metadata (e.g. MODS, EAD, VRA Core...). Several institutions have committed in one degree or another to their use, and many more are investigating the possibility. To provide a venue for more specific discussion (implementations, code sharing, etc.) I've created a list at:

https://list.mail.virginia.edu/mailman/listinfo/xforms4lib

I hope we can generate some useful discussion there, and perhaps even some partnership-building. As my colleague Ethan Gruber has pointed out to me, there are at least four or five institutions implementing MODS editors alone. It would seem that there's a lot of room to help each other.
