Bug ID: 18265
Summary: Followup to Buuug 17196. deletedbiblio_metadata is not
used. biblioitemnumber was forgot.
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5 - low
Component: Cataloging

Exhibit 1:
The MARCXML is lost when the biblio is deleted because the values in
biblio_metadata-table from biblioitems-table are never moved to
deletedbiblio_metadata-table.
Previously the marcxml was preserved in the oldbiblioitems-table
This is a challenge for gathering statistics
For example item has been ordered, received, and removed from collection during
the statistics period
Information in marcxml is needed to accurately categorize the item
Exhibit 2:
[15:22:38] <kivilahtio> also. In Koha there once was a great idea that one
biblio-entry can have multiple biblioitems
[15:22:45] <kivilahtio> and the marcxml was tied to the biblioitems-table
[15:23:11] <kivilahtio> this is a nice idea, but nobdy really cared for it and
now biblionumber and biblioitemnumber are used interchangeably
[15:23:22] <kivilahtio> except when they get out of sync during a data
migration
[15:23:41] <kivilahtio> then things start to work really interestingly
[15:23:47] <kivilahtio> but the point is
[15:23:57] <kivilahtio> biblio_metadata has a biblionumber-column
[15:24:15] <kivilahtio> shouldn't it have a biblioitemnumber-column, just for
old time's sake?
In the biblioitems-table we had marcxml. primary keyed with biblioitemnumber.
Now the marcxml is moved to biblio_metadata and the foreign key reference was
simplified to biblionumber.
This makes the existing FRBR-bug worse.
