Description David Bourgault 2018-05-04 18:04:03 UTC
When choosing an authority for a zone in the bibliographic notice editor, existing fields are not cleared.

So if I have a information in the subfields $a $v $9 and I import a authority notice with subfields $a $9 $x, the previous $v value is not cleared.

Hi David,
We solved a similar (but not identical!) problem in AuthoritiesMarc::merge while updating biblio records for a changed authority. Merge now looks at the pref AuthorityMergeMode and in strict mode deletes the other fields (like $v above).
It sounds logical to me now to clear the fields too in the editor when you set this pref to strict mode.
But note historical behavior is 'loose' mode and default. And perhaps even closer to the MARC standard..

In short, we cannot delete the other values no-matter-what.
