Re: Historical events

Hi Allison

Yeah I think the Schema definition could change, the dictionary definition
doesn't mention a place requirement. Technically you could say it happened
on Earth, but I agree the requirement shouldn't be there.

In my view, just my view, the museum probably needs to specify it's own
type for period, which then may or may not be used to classify the
top-level events of any event hierarchies it describes (it could describe
more levels than just the top levels, how far down is probably subjective).
My reasoning is in my last message about types requiring a clear meaning in
Schema.

Ask me if I'm not clear, I like working this through.
