Hi,<br>
<br>
there is no good way to un-merge.<br>
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.<br>

<div>Btw. when reading the PIMO guide [3], it
says on page 31 to copy all identifiers. Do
I understand it correctly that it should
copy all identifiers from new
NCO:PersonContact into PIMO:Person (and
should I do that too)? This seems like
an unnecessary data duplication. <br>

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.<br>

This is why it would be good to copy all identifiers

<div class="im">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). </div>

<div>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.</div>
<div><br>
</div>
<div>Or is there any good way how the un-merge can be done?</div>
