AuthDisplayHierarchy
Asks: ___ broader term/narrower term hierarchies when viewing authorities.
Default: Don’t show
Values:
Don’t show
Show
Description:
When set to 『Show』 broader and narrower 『See also』 references will be displayed in a tree at the top of the record in both the staff interface and the OPAC.
For MARC21, in order for this display to appear, the records must have 5XX with the relationship code in $w and the authority number (authid) in $9.
備註
The relationship codes in $w can be found on the Library of Congress website under Tracings and references-General information
g - Broader term
h - Narrower term
For example, the records in the above screenshot have the following information:
Authority #3 001 3 151 $a Germany 551 $w h $a Baden-Württemberg (Germany) $9 4 Authority #4 001 4 151 $a Baden-Württemberg (Germany) 551 $w g $a Germany $9 3 551 $w h $a Konstanz (Germany) $9 5 Authority #5 001 5 151 $a Konstanz (Germany) 551 $w g $a Baden-Württemberg (Germany) $9 4警告
The relationships must be bidirectional, meaning the broader term must reference the narrower term and the narrower term must reference the broader term.
Linker
These preferences will control how Koha links bibliographic records to authority records. All bibliographic records added to Koha after these preferences are set will link automatically to authority records, for records added before these preferences are set there is a script (misc/link_bibs_to_authorities.pl) that your system administrator can run to link records together.
CatalogModuleRelink
Default: Do not
Asks: ___ automatically relink headings that have previously been linked when saving records in the cataloging module.
Values:
Do
Do not
Description:
Longtime users of Koha don’t expect the authority and bib records to link consistently. This preference makes it possible to disable authority relinking in the cataloging module only (i.e. relinking is still possible if link_bibs_to_authorities.pl is run). Note that though the default behavior matches the previous behavior of Koha (retaining links to outdated authority records), it does not match the intended behavior (updating biblio/authority link after bibliographic record is edited). Libraries that want the intended behavior of authority control rather than the way Koha used to handle linking should set CatalogModuleRelink to 『Do』. Once setting this to 『Do』 the following preferences can also be set.
LinkerKeepStale
Default: Do not
Asks: ___ keep existing links to authority records for headings where the linker is unable to find a match.
Values:
Do
Do not
Description:
When set to 『Do』, the linker will never remove a link to an authority record, though, depending on the value of LinkerRelink, it may change the link.
LinkerModule
Default: Default
Asks: Use the ___ linker module for matching headings to authority records.
Values:
Default
Retains Koha’s previous behavior of only creating links when there is an exact match to one and only one authority record; if the LinkerOptions preference is set to 『broader_headings』, it will try to link headings to authority records for broader headings by removing subfields from the end of the heading
First match
Creates a link to the first authority record that matches a given heading, even if there is more than one authority record that matches
Last match
Creates a link to the last authority record that matches a given heading, even if there is more than one record that matches
Description:
This preference tells Koha which match to use when searching for authority matches when saving a record.
LinkerOptions
Asks: Set the following options for the authority linker ___
Important
This feature is experimental and shouldn’t be used in a production environment until further expanded upon.
Description:
This is a pipe separated (|) list of options. At the moment, the only option available is 「broader_headings.」 With this option set to 「broader_headings」, the linker will try to match the following heading as follows:
=600 10$aCamins-Esakov, Jared$xCoin collections$vCatalogs$vEarly works to 1800.
First: Camins-Esakov, Jared–Coin collections–Catalogs–Early works to 1800
Next: Camins-Esakov, Jared–Coin collections–Catalogs
Next: Camins-Esakov, Jared–Coin collections
Next: Camins-Esakov, Jared (matches! if a previous attempt had matched, it would not have tried this)
LinkerRelink
Default: Do
Asks: ___ relink headings that have previously been linked to authority records.
Values:
Do
Do not
Description:
When set to 『Do』, the linker will confirm the links for headings that have previously been linked to an authority record when it runs, correcting any incorrect links it may find. When set to 『Do not』, any heading with an existing link will be ignored, even if the existing link is invalid or incorrect.
