In thinking about how to mesh VOEvent with the science ontology, it
appears that VOEvent is a kind of Publication. Perhaps under Report.
This is where IAU_Circular would also go. Publications would have
hasDescription and that would have subProperty hasExplanation. The
range of hasExplanation would include Explanation, Hypothesis, Theory,
Postulate, Fact and Axiom where:
VOEvent would take Hypothesis and Theory
Hypothesis - One of several possible testable explanations
Theory - Only known explanation that fits the observed data.
Hypothesis and Theory could in turn have hasExplanation of:
Postulate - statements of assumptions needed to continue the line of
Axiom - a truth commonly accepted and in no need of proof.
Fact - Real world facts (New York is in the US) and Mathematically or
logically proven statements.
The VOEvent is different from ast:Event because an instance of an
ast:Event is the event itself not claims about the event. However,
times, locations and measurements of the event do belong in ast:Event.
Once there is a theory of the event it can be subclassed to the specific
type of event that it is (ast:supernova etc).
