[Data-modeling] Astronomy: Discovery Properties

[Jeff Prucher]

To model it as an event, assuming that this means to use the "event" type to
record information about the discovery of an object, requires the creation
of topics like "The Discovery of Pluto". But all using the "event" type gets
us is the start and end dates, and an inclusion/included by tree, the latter
of which probably doesn't apply. This actually seems like more work for less
payoff than just using the properties "discovered by" and "discovery date",
since "discovered by" would have to be on a new type ("astronomical
discovery") that included the type "event". Unless you had something else in
mind, in which case kindly ignore this message.
