I've just started looking at JSON data, and for (my) educational purposes, would like to see how the entire task gets done in the greatest generality. It seems that all of the values for 'label' are the ones beginning with caps. JSON material gets bought up in SoPW fairly frequently, but I don't see any tutorial about it as I scroll through. (Maybe a question like this could motivate one.)
