[OPEN-ILS-DEV] [OPEN-ILS-GENERAL] bibkey field issues when importing holdings into staging_items table

I'd be tempted to make one.  Use Perl and MARC::Record and run through
each record and add a custom tag, say 901, and put an incrementing
number in subfield a.  Make sure you start the sequence above the
max(id) of the biblio.record_entry (BRE) table in your database.  When
you load the bibs, modify the loading process to use that value as the
BRE id.  After loading the bibs, reset the sequence in the database to
make sure its "nextval" will start above the new max(id) of BRE.

Then when you parse out the holdings, you know the exact BRE id used
and can link them up.

If I'm understanding correctly (just looking at the holdings import
demo bundle), the bibkey is supposed to point to the BRE id for the
bib record.  If you're just using a sequence there, then you may not
be linking them to bib records at all, much less the right ones.

Am I misunderstanding?
