XForms and Orbeon are very interesting tools for developing metadata management tools.
The ONIX developers have used this stack to produce an interface for ONIX-PL called OPLE that people should try out.
Questions about Orbeon relate to performance and integrability, but I think it's an impressive use of XForms nonetheless.
