[Data-modeling] New Extrasolar Planet type is up for your consideration (hope to promote to Astronomy soon)

User metapsyche initiated the type and has done of most of the hard  
work of modeling/adding the properties to hang off of exoplanet. He  
has also added most if not all instances of exoplanets Freebase  
currently contains from previous topic refreshes from Wikipedia.

We hope you find the properties useful. If there are any mistakes,  
missing properties or units of measurement questions please reply to  
me (and the list).

Several questions I have been pondering:

Use of parsec versus light year (from what I understand, light years  
are used as a unit of length/distance for science popularization  
purposes and parsecs is preferred?)?

Trying to figure out if a survey, like that of the TrES that is  
composed of three telescopes at different observatories, is an  
Astronomical Organization or that of an Astronomical Survey? Super  
WASP? Minor Planet Center?

IAU, definitely an astronomical organization.

We've just started with the organization and the instrumentation  
(Astronomical Observatory and Telescope just placeholder types at the  
moment). As for Astronomical Observatory, it probably should be two  
types at first in an enumerated list: Space Observatory (includes  
satellite/spacecraft types) and Terrestrial Observatory (includes  
Structure). But unsure how to accomplish this.

It would be great to be able to have two different set of properties  
populate a topic when a trigger property (boolean I guess) would be  
the only initial property. E.G. Astronomical Observatory, is it  
Terrestrial-based? (True /False) and depending on the state of the  
boolean, space or structural properties would be made available for  
data.
