when it comes to a registry, I suggest we ask Mitsuharu Nagamori to  
give us his - he has built the registry for the Dublin Core Initiative  
and other things and I think as a trusted and ready-to-roll registry,  
we could not do better. In fact, I am not sure we even need our own  
one - we could simply add our schemas etc to the existing registry, I  
think, to our benefit.
