[Zope] LocalFS customization - Upload Method

Hi everybody, I'm trying to build a big file library which can be accessible through my zope server. So I've installed LocalFS. It's very good but I'd like to customize it a little bit : I made a Zclass wich contain informations concerning one file (like title, author, subject...). I'd like to be able to upload a file in my LocalFS object (easily with a form) and then to create a Zclass instance whith the id of the file. How can I modify the upload method to be able to do that ? Thank you in advance.
