After reading the documentation that is sent along with the appointments bulk data, especially section 4.5, I have a question.
I seem to understand that:
1) the entity "person" in CH is composed with a name and a URA.
2) a "person" is given a pnr of the type 123456780000
3) As of 2009, URAs are not public, but CH does receive notifications of changes to both names and URAs for a specific appointment.
4) When changes to either name or URA (actual new values in URA are not public) happen, the last 4 figures of the pnr increment.
My question is then the following: it seems to me that to get the unique ID for a person, I need to get the first 8 digits of the pnr.
Is this correct? Or is there any unintended consequence in this approach?
Thanks a lot!
