[Clipart] metadata: aren't the keywords actually categories (and can keywords be added)?

One big XML is totally useless to applications that don't understand the 
format.  Currently, I can use OCAL images in the GIMP, Inkscape, Mozilla 
Composer, etc. etc.  Many of those can only handle bitmaps; that's fine, 
since the package contains bitmaps.

It's true that people who can run the specialized clipart-tool can extract 
files from the XML and save them to somewhere in their home directory, but 
this adds an extra step before using the image in each of those programs. 
And if you can't use the specialized clipart-tool... (for example, I don't 
have a Java VM on my machine).

If the problem is "what do you do with files in multiple categories", there 
are lots of solutions.  Hard links are great; symlinks are fine too.  If 
you use tar, whatever tool untars the files will presumably do a credible 
job of simulating them on machines that don't have them (probably make 
copies for hardlinks and shortcuts (?) for symlinks).  Extra copies are 
fine too, unless we get loads of files in too many categories.  You could 
even just fall back to putting the file in the "best" (or first) place that 
comes to mind.

Surely you can support any format we document, without much trouble?
