I think the missing element is this: you need to establish that the domain that you are trying to measure is a metric space before trying to measure distance us

I think the missing element is this: you need to establish that the domain that you are trying to measure is a metric space before trying to measure distance using this formula.

edit: read the second section on how to establish something is a metric space. (in the wiki article)
