Records with no 901 values

Asked by George Duimovich on 2011-06-17

EG 2.0.6
PG 8.4

Probably a local data issue, but if so not sure how common this might be for other 1.6->2.0 upgrades.

I came across a record without an 901 system generated tag so we looked at how many others were in the system since the 2.0.6 upgrade. We found about 11,000 such records (or about 2% of our bibs):

select id from biblio.record_entry
where id not in (select distinct(record) from metabib.real_full_rec where tag = '901' and subfield = 'c')

Looking at a bunch of these records we can see one common thread is that they have empty 001 tags (no indicators / subfields). A snippet from the Flat Text Editor view of such a record looks like this:

=LDR 00881nam a22001937a 4500
=005 20100520153539.0

If I view and then save the record in the Staff Client, the 001 and 901 values are populated.

Unless otherwise advised, I'll just proceed with re-ingesting them the 2.0 way:

Note, this was resolved during the 2.2-2.3 upgrade scripts and involves reingesting the bib records after upgrading to newer versions of Evergreen.

Can you help with this problem?
