Comment 4 for bug 254595

The basic problem underlying both these bugs is that we have no representation for the file's metadata. Sending GET to the file just redirects you to the library. If there was a JSON representation of the file we could serve filename, timestamp, etc for clients who requested JSON. For clients who expressed no preference as to file type we could serve the redirect.

But there's another problem specific to this bug, which is that when Launchpad overwrites a file it changes its name to 'data' instead of using the existing filename. I'm looking into that now.
