Guessing the filetype is something I was working on in a newer version
of the upload script, but I have to iron out some performance problems
with that before it will be ready to replace the current one. (I have
a pretty good idea what I have to do; I just have to do it.) So, for
now, the filetype still has to be specified.
As far as the upload box on the main page not having any way to
specify that, it used to, but that got lost in the site redesign. The
upload form that you get if you click the "Submit Clip Art" link in
the sidebar is more complete. (You don't need to fill out anything
that is already specified in the metadata.)

The embedded RDF cannot be read until the filetype is determined.
(Some supported filetypes do not embed RDF, and the ones that do don't
all embed it in the same way.) If you specify the filetype, the RDF
should be read then, and these other errors should vanish.
Once again, guessing the filetype if possible *is* on the TODO list;
it just isn't done yet.

What does everyone else think about this?

The upload script on the server does not know what the filename was on
your computer; it creates a new filename based on the title. I could
fix this by replacing CGI::Lite with a handrolled form-parsing
routine, which I have thought about doing anyway, due to a bug we have
been experiencing wherein some files get corrupted in the upload

This is something I definitely need to look into. We've been seeing
similar things like this happen in various places, from time to time.

I'm not sure what SVG::Metadata currently supports in the way of
dates. I'd have to investigate that.
