I'm thinking about implementing (yet another ;-) a middleware solution for our library system using Zope. The challenge is I need to pass metadata from one web catalog to another (imagine adding books from Amazon.com to a Barnes & Noble.com shopping cart). The system on the recieving end provides for this capability using OpenURL (http://library.caltech.edu/openurl/). I know I've heard of this before, but have always overlooked it in favor of a more popular XML-RPC type communication. Now that I'm taking the time to examine it, I see more potential here than I originally assumed. Is anyone else familiar with this spec? It seems the NISO has not yet made this an official standard, as all that is available is lots of draft papers. It should solidify over the next year or so, however. I'm always on the hunt for new things to Zope-ify, and this might be a good one.
