Ugh.

Indeed.  And the layout probably will change, if not soon then
eventually.

There is one, here:
http://openclipart.org/clipart/index.xml

This file indexes the most important metadata (authors, keywords,
titles, and title words) and gives the relative path to each file that
has them.

We have thought about also including a manifest.xml that would not
index the metadata but just list every included file, but at the
time of this writing we have not done that.

If we did, which would be better for you to use, the index, or the
manifest?  Why?

This is similar to what a manifest would look like, if we included
one.  It wouldn't be exactly like that, but along those lines.  It
probably would also list the .png thumbnails and the various
meta-files (LICENSE and so forth) somehow.  We had not worked out
a format for it in detail yet, mainly because we just hadn't gotten
around to it.
