That indeed will help. We planned on creating the XMP from the RDF, but 
getting it directly would be much better.

So I gathered. Is there a plan to add them to the web service?

I read the api documentation and gathered that.

Then again, the public domain license is also static, i.e., doesn't have any 
questions to be answered. So why aren't the rest of the licenses (the various 
GNU licenses, the Wiki, Developing Nations, etc.) supported?

And in addition, is there a way to work with a specific future version of the 
web service? I wouldn't want to write code that uses the /dev web service, 
because when the next version is stabilized, the URL will change to 2.0 or 
3.0 or whatnot, and the /dev version will move on. So is there an option to 
use the 2.0 version (even while it is being developed) from a /2.0 URL?
