Again, because of VOEvent and RTML, I'd like to suggest we include at  
least

	event				(physical or observational event)
	event.burst			("sudden" observed change in state)
	event.chirp			(continuous change in frequency)
	event.discovery		(discovery of previously unknown object)
	event.eclipse			(intrinsic eclipse of physically related objects)
	event.eruption			("sudden" physical change in state resulting in  
more/less observed emission)
	event.explosion		(physical explosion)
	event.glitch			(discontinuous change in frequency)
	event.occulation		(extrinsic occulation of physically unrelated  
objects)
	event.variation			(variation in some observable property)
	event.variation.phot		(photometric variation)
	event.variation.pos		(astrometric shift in position)
	event.variation.spect	(spectroscopic variation)

If we're going to have solar system UCD's, then it's only fair to have  
stellar and
extragalactic ones:  I suggest looking at

	http://monet.uni-sw.gwdg.de/twiki/bin/view/VOEvent/ 
UnifiedContentDescriptors

were there are unit UCD's like "stars", "ism", "galaxy" (as in milky  
way), "galaxies", and "cosmology".
Yes, we don't have to adopt ALL of them, but it would help to have the  
basic ones.

Rick
