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.
