Quoting Alan Rykhus <[email protected]>:
Hello,
I had a question about the config.global_flag cat.bib.use_id_for_tcn
setting.
I was working on a migration and was having issues because of this. I
was planning on using the tcn_value for linking purposes later on as I
had in a previous conversion. I put the a number in here from the old
system that helps me find the bib and link items, loans, holds, etc. to
the bib.
1. What ramifications will we have if we set this flag to false?
Your bib ids will not match the TCN.
2. What happens if we then set it to true after we are done with the
migration? I can see where the actual biblio.record_entry.id will
eventually become the same value as migrated
biblio.record_entry.tcn_value entries and there would be duplicates.
Will this be a problem?
Yes, it most likely will. If you set the flag to false, you should
leave it false. TCNs are supposed to be unique per record source.
I see there are a couple of bug reports on this(really 1, the second is
a duplicate). But I did not find anything referring to the functionality
this flag is trying to accomplish.
thanks -- al
