But DwC is already normalized this way.  There is no LocalityID term in the
Event Class. There is no EventID in the Occurrence class.  In fact, the only
"foreign key" term I know of in DwC (internet too slow here for me to
consult it online) is "IndividualID", and this doesn't even serve the
function even a "Foreign Key" because there is not yet any "indivudal" class
to provide "PK" of the corresponding linked instance.

So...I've been asking various people how one is supposed to represent the
fact that "This Event instance took place at this Locality instance", or
"This Identification instance refers to this Taxon instance", or "This
Occurrence instance involves this Event instance and this Identified Taxon
instance".  So far, I don't know the answer to this.  For the BiSciCol
project, these relationships between instances of DwC classes are the core
item being indexed, so we are assuming that the purpose of
ResourceRelationship is, in fact, to establish these relationships between
instances of DwC classes.

I hope someone will correct me if I'm wrong.
