as usual no time to write a long mail, but I wanted to quickly respond
to your 3 intended uses below.
The idea is that everyone of them has a dwc:scientificName term and
potentially also the other terms you listed at the end like rank.
originalTaxonNameID and acceptedTaxonID are still properties of the
described dwc:scientificName and act like foreign keys linking one
name/taxon to another. So if you have some sort of synonym (indicated
by dwc:taxonomicStatus) the dwc:acceptedTaxonID will point to what is
considered the accepted taxon. While originalTaxonNameID will point to
the original name record. The verbatim non ID versions of these two
terms do essentially the same, but are based on name string matching.
They are not meant to replace the use of dwc:scientificName in a record.
Maybe its best to look at the examples Dave put together:
(the tax/nom status columns are subject to change)
