The "cutting edge" will always be such that one won't have a useful  
classification scheme other than unusual combinations of the more  
general bits and pieces.  That's why the UCD has to be hierarchical (to  
emphasize/extract general properties even when given specifics) and  
easily combined.  Let's see.....

		cosmology.dark_energy	<==	cosmology.background;em.microwave
								cosmology.background.polarization;em.microwave
								stars.supernova.Type_Ia;process.eruption.hydrodynamic; 
process.eruption.thermonuclear
								galaxies.velocity_curve
								cosmology.abund
								....

(Aha - already discovered a few important UCD's to add....!)
