I'd do that quite differently: Collect metadata about files in extended attributes (which are rather universally useable), and do it =66rom an userspace daemon/application/file manager plugin which uses dynamically loadable plugins for the different file types differentiated by libmagic. This has nothing to do in the kernel.
