Hi,
there is no good way to un-merge.
its of course ok to not copy the identifiers to the pimo:Person. The
spec was implemented in scientific prototypes and they did not have
to stand the test of time.

identifiers:
Copying the email addresses and other identifiers to
the pimo:Person will help you identifying arbitrary
data. Given you have some new data coming into the
system, you may want to check if its already known.
("is this "Dirk"
guy someone we know?). This is the "Check identifiers"
step In Section 11.1 on page 30, where you check if
you find a Pimo:Person that represents the resource
you are working with.
This is why it would be good to copy all identifiers
over to the pimo:Person, to speed up lookups later.
its data duplication, but it doesn't
matter. The key point here is: you want to be veeery
quick when identifying if any new data does mean
something to you. And optimizing this read-accesses
is always good. Say you read 100 emails a day,
roughly 10.000 a year. Quickly checking them against
the 1000 contacts you have is nicer if the
identifying information is all in one place (that
would be the pimo:Persons).
Actually after giving it some thought, it is not a good
idea to copy data into PIMO:Person. Imagine a use case, where
you accidentally merge NCO:PersonContact with PIMO:Person,
which is not supposed to be there. Then it's very hard and
problematic to un-merge it. If you add it just as a grounding
occurence, it's easy to just remove this relation.
Or is there any good way how the un-merge can be done?
