Maybe the thing to do is take a simple example like books and start 
growing RDF and XML Schema representations with evolving emphasis on 
data description, data querying, and data display.  (Did someone say 
use case?)  Detailed implementations, such as were recently 
referenced on this list, are valuable resources, but starting at the 
beginning might provide real value.  Then maybe we can add some meat 
to the Cambridge Communique.
