AdditionalFieldsInZ3950ResultAuthSearch
Version
This system preference was introduced in version 23.11 of Koha.
Asks: Display the MARC field/subfields ___ in the ‚Additional fields‘ column of Z39.50 search results (use comma as delimiter e.g.: „001, 035$a“).
Beschreibung:
This system preference lets you display additional information from the MARC record in the authority Z39.50/SRU search result lists.
AuthDisplayHierarchy
Fragt: ___ Hierarchien für weitere/engere Terme zwischen Normdaten.
Standardwert: Zeige keine
Werte:
Zeige keine
Zeige
Beschreibung:
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.
Bemerkung
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 4Warnung
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.
AutoLinkBiblios
Asks: ___ attempt to automatically link headings when saving records in the cataloging module.
Default: Don’t
Werte:
Verlinke
Don’t
Beschreibung:
This system preference determines whether or not Koha will attempt to link terms in authority controlled field to existing authority records upon saving a new bibliographic record.
This system preference is used when creating new bibliographic records. CatalogModuleRelink and LinkerRelink are used when editing bibliographic records.
If set to „Do“, Koha will search in the thesaurus to find a matching authority record. If it finds one, it will link it. If it finds more than one, LinkerModule will determine which one is linked.
If set to „Don’t“, no linking attempt will be made when saving a new bibliographic record.
CatalogModuleRelink
Fragt: ___ zuvor bereits in der Katalogisierung verlinkte Ansetzungen erneut.
Default: Don’t
Werte:
Verlinke
Don’t
Beschreibung:
This system preference determines whether or not authority links are checked and adjusted when saving a bibliographic record.
When set to „Do“, Koha will automatically relink headings when a record is saved in the cataloging module when LinkerRelink is turned on, even if the headings were manually linked to a different authority by the cataloger.
Bemerkung
This system preference requires that AutoLinkBiblios be set to „Do“.
LinkerConsiderThesaurus
Asks: ___ compare the source for 6XX headings to the thesaurus source for authority records when linking.
Default: Don’t
Werte:
Don’t
Verlinke
Beschreibung:
This system preference is used to enable multiple thesauri support for authorities.
The thesaurus used for the term is added to the authority record using 040$f.
In the bibliographic record, set the second indicator to 7 for 650 and add the source to 650$2. For local terms, use 4 (Source not specified) as the indicator.
Example for a bibliographic record:
650 _ 0 $a Feminism 650 _ 7 $a Feminism $2 sao 650 _ 7 $a Feminism $2 barn
The first example above is the LCSH term. The other two terms are from sao (controlled Swedish subject heading system) and barn (Swedish children subject heading system). These three are using the same TOPIC_TERM Feminism, but they belong to different thesauri.
Warnung
In existing systems, enabling this preference may require a reindex, and may generate new authority records if AutoCreateAuthorities is enabled.
Bemerkung
Support for multiple authority thesauri currently only works with ElasticSearch.
LinkerKeepStale
Standardeinstellung: Verlinke nicht
Fragt: ___ bestehende Verlinkungen der Ansetzungsformen, wenn der Linker keinen Treffer erzielt.
Werte:
Verlinke
Verlinke nicht
Beschreibung:
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
Voreinstellung: Default
Fragt: Verwende das ___ Linker-Modul um Ansetzungen mit Normdatensätzen zu verlinken.
Werte:
Standard
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
erster Treffer
Creates a link to the first authority record that matches a given heading, even if there is more than one authority record that matches
letzter Treffer
Creates a link to the last authority record that matches a given heading, even if there is more than one record that matches
Beschreibung:
This preference tells Koha which match to use when searching for authority matches when saving a record.
LinkerOptions
Fragt: Verwende folgende Optionen für den Normdaten-Linker ___
Wichtig
Diese Funktion ist experimentell und sollte nicht in einer Produktionsumgebung verwendet werden, solange sie noch nicht weiter ausgebaut ist.
Beschreibung:
Dies ist eine durch einen pipe (|) getrennte Liste von Optionen. Die einzige momentan verfügbare Option ist „broader_headings.“ Wenn dies eingestellt ist, versucht der Linker, die folgenden Normdaten wie folgt zuzuordnen:
=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
Standardwert: Verlinke
Fragt: ___ Ansetzungen erneut, die bereits zuvor mit Normdaten verlinkt wurden.
Werte:
Verlinke
Verlinke nicht
Beschreibung:
Bei der Einstellung „Verlinke“ verlinkt der Linker bei der Ausführung die Links für Ansetzungen, die zuvor mit einem Normdatensatz verknüpft wurden erneut, und korrigiert alle fehlerhaften Links, die er möglicherweise findet. Bei der Einstellung „Verlinke nicht“ werden alle Ansetzungen mit einem vorhandenen Link ignoriert, auch wenn der vorhandene Link ungültig oder falsch ist.
