If autolinking is enabled, there are scenarios where the authorities merge process
updates the record, then sends it to ModBiblio which then AutoLinks the record, undoing
the changes in the record (as the 'from' authority is not removed until the process is complete)
This patch simply disables the autolinking process when merging authorities
To test:
Set system preferences
AutoCreateAuthorities = don't generate
RequireChoosingExistingAuthority = don't require
AutoLinkBiblios = Do
CatalogModuleRelink = Do
LinkerKeepStale = Don't
LinkerModule = first match
LinkerRelink = Do
1. Create an authority record
1.1. Go to Authorities
1.2. Click on "New authority" and choose an authority type (I chose Corporate name)*
1.3. Fill in the mandatory fields (000, 003, 005, 008, 040)
1.4. In tab 1, click on the label of the main heading (110 for Corporate name)
1.5. Fill in subfield
1.6. Copy content of subfield
1.7. Click on "Save"
1.8. Note the authority record number
2. Duplicate the authority record
2.1. Click on "Edit" and choose "Edit as new (duplicate)"
2.2. Click on "Save"
2.3. Click on "No: Save as new authority"
2.4. Note the authority record number (should be the number from step 1.8 +1)
3. Link one of the authority records to a bibliographic record
3.1 In another tab, do a catalog search
3.2. Click on "Edit record" under one of the search results
3.3. Go to the relevant tab (for corporate name, I used field 710 in tab 7)
3.3.a. If there are no empty fields for that tag, click the "Repeat this tag" button (two rectangles)
3.4. Paste the text previously copied in subfield
3.5. Click on "Link authorities automatically" at the top of the page
3.6. Note the authority record number in subfield
--> The linked authority record should be the first authority record (step 1.8)
3.7. Click on "Save"
4. Merge the two authority records, keep the one that is not linked to the bibliographic record
4.1. Go back to the tab with the authorities
4.1. Go to Authorities
4.2. Search for the aurhorities previous created
4.2. Click on "Actions" and choose "Merge" for both records
4.3. Select the record number that is NOT linked to the bibliographic record
4.4. Click on "Next"
4.5. Click on "Merge"
5. Check the bibliographic record
5.1. Go back to the tab with the bibliographic record and refresh the page (Ctrl+F5)
5.2. Hover the mouse cursor over the name or term, without clicking
5.3. Note the record number that appears at the bottom of the screen
--> The record number was not changed
6. Apply the patch
6.1. Run prove t/AuthoritiesMarc_MARC21.t
6.2. Repeat Previous steps 1, 2, 3, 4, 5
--> The record number is change

|

[ override_limit => 1, ]
|
|
});
|
|
|
|
Merge biblios linked to authority $mergefrom (mandatory parameter).
|
|
If $mergeto equals mergefrom, the linked biblio field is updated.
|
|
If $mergeto is different, the biblio field will be linked to $mergeto.
|
|
If $mergeto is missing, the biblio field is deleted.
|
|
|
|
MARCfrom is used to determine if a cleared subfield in the authority record
|
|
should be removed from a biblio. MARCto is used to populate the biblio
|
|
record with the updated values; if you do not pass it, the biblio field
|
|
will be deleted (same as missing mergeto).
|
|
|
|
Normally all biblio records linked to $mergefrom, will be considered. But
|
|
you can pass specific numbers via the biblionumbers parameter.
|
|
|
|
The parameter override_limit is used by the cron job to force larger
|
|
postponed merges.
|
|
|
|
Note: Although $mergefrom and $mergeto will normally be of the same
|
|
authority type, merge also supports moving to another authority type.
