Good point. I think we are talking about this:

1) gnumed-internal patient record primary key
   - this we got handled with
   - we use this inside one database for foreign keys
   - we do use it across services via xlnk_identity
   - we cannot, however, rely on the latter

2) to alleviate the latter in 1) we need
   - an identifier with meaning
   - for use across databases
   - suited to computation (eg. defined structure, not just
     arbitrary free text)
   - human readable, however
   - short, concise format
   - which to me is the GnuMed PUPIC

3) the GnuMed "internal" Patient ID
   - this is just some assigned identifier within one
     "GnuMed eChart system" handy for referring to patients
   - eg, the primary key of a patient can change across
     dump/reload of the entire database
   - the GnuMed internal Patient ID cannot, however
   - this is easily done via ext_person_id rows

So the order of importance is like this ?

1) full name at birth
2) date of birth in Gregorian Calendar
3) mothers name at birth of person

4) ethnicity
5) country of birth at time of birth

with 4 and 5 only really starting to be useful in countries
with high percentages of first-generation immigrants...

Ethnicity before country of birth since second-generation
immigrants are often still of original ethnicity but not of
different cob.

Comments ?  Should the results of this discussion be collected
in the Wiki ?

My experience from Thailand makes me suggest this, BTW.
