Organization property improvement

[JulieWinchester]

Need to survey organization properties for improvements that could be made. As a start:

• We have the field http://www.morphosource.org/terms/ms/address. This is currently a sub-property of dwc:locality, and ms:address could be replaced entirely with dwc:locality. However, probably better would be to replace it with https://schema.org/address and then note somewhere it’s more or less equivalent to dwc:locality.
