I believe there's an alpha/beta-level release of both a dtrace kernel
module and the user-space tools for Linux. There's also SystemTap which
should give you similar data. I've only used dtrace on Solaris and
haven't used SystemTap at all, so YMMV.

I don't think so, but you might be able to accomplish the same thing at
the application level. If you have a limited set of applications, you
could have them write the metadata you need into a database as they
create and update files.
