AuthDisplayHierarchy

Predefinito: Non mostrare

Chiede: ___ le gerarchie tra Broader Terms e Narrower Terms quando mostri le autorità.

Valori:

• Visualizza

  

• Non mostrare

Descrizione:

• Se i tuoi record di autorità comprendono dei campi 5xx con riferimenti «vedi anche» a BT o NT, questa preferenza abilita la visualizzazione di queste autorità in alto nel record.

AuthorityControlledIndicators

Asks: Use the following text to edit how authority records control indicators of attached biblio fields (and possibly subfield $2). Lines starting with a comment symbol (#) are skipped. Each line should be of the form: (marc21|unimarc), tag, ind1:(auth1|auth2|some_value), ind2:(auth1|auth2|thesaurus|some_value). Here auth1 and auth2 refer to the indicators of the authority record, tag is a biblio field number or an asterisk (*), and some_value is a fixed value (one character). The MARC21 option thesaurus refers to indicators controlled by authority field 008/11 and 040$f.

Descrizione:

• Used when merging authorities.

• Controls how the indicators of linked authority records affect the corresponding biblio indicators. Currently, the default value is fine-tuned for MARC21 and copies the authority indicators for UNIMARC.

• For example, a MARC21 field 100 in a biblio record should pick its first indicator from the linked authority record. The second indicator is not controlled by the authority. This report supports such MARC conventions.

AuthorityMergeLimit

Chiede: Quando si modifica un record di autorità, non aggiornare i record bibliografici associati se il loro numero eccede ___. (Sopra questo limite, provvederà il :ref:` cron job merge_authority <cron-update-authorities-label>`.)

Default: 50

Descrizione:

• This system preference determines the maximum number of bibliographic records that can be updated when an authority record changes.

• This helps prevent overusing resources if an authority record is linked to many bibliographic records.

• Make sure to enable the merge_authority cron job to catch the updates that wouldn’t otherwise be transferred to bibliographic records.

AuthorityMergeMode

Default: loose

Chiede: quando si aggiornano i record bibliografici da un record di autorità associato («merging»), gestisce i sottocampi dei campi record del record bibliografico nella modalità ___. Nella modalità strict i sottocampi che non si trovano nel record di autorità vengono eliminati. Nella modalità loose li manterrà. La modalità loose è il comportamento storico e rimane l’impostazione predefinita.

Valori:

• loose

• strict

AutoCreateAuthorities

Predefinito: non generare in automatico

Chiede: Quando modifichi i record bibliografici, ___ i record di autorità mancanti.

Valori:

• Non generare

• genera in automatico

  Importante

  BiblioAddsAuthorities deve essere impostata su «Permetti» affinché questo abbia effetto

Descrizione:

• Quando questa e la preferenza BiblioAddsAuthorities sono entrambe attive, vengono automaticamente creati dei record di autorità per le intestazioni che non sono presenti negli indici. Quando BiblioAddsAuthorities è attiva e AutoCreateAuthorities non lo è, non vengono automaticamente creati dei record di autorità al salvataggio del record bibliografico, ma l’utente può inserire delle intestazioni non presenti negli indici di autorità. Se BiblioAddsAuthorities è disattivata, la preferenza non ha effetto.

BiblioAddsAuthorities

Predefinito: permetti

Chiede: quando modifichi i record bibliografici, ___ di creare nuovi record di autorità, anziché dover necessariamente fare riferimento a record di autorità già esistenti.

Valori:

• permette

  • Questa impostazione permette di inserire valori nei campi controllati dagli authority e aggiungere un nuovo record di autorità se non esiste già

• don’t allow

  • This setting will lock the authority controlled fields, forcing you to search for an authority versus allowing you to type the information in yourself.

MARCAuthorityControlField008

Default: || aca||aabn | a|a d

Asks: Use the following text for the contents of MARC21 authority control field 008 position 06-39 (fixed length data elements).

Importante

Do not include the date (position 00-05) in this preference, Koha will calculate automatically and put that in before the values in this preference.

Descrizione:

• This preference controls the default value in the 008 field on Authority records. It does not effect bibliographic records.

UNIMARCAuthorityField100

Default: afrey50 ba0

Asks: Use the following text for the contents of UNIMARC authority field 100 position (fixed length data elements).

Importante

Do not include the date (position 00-07) in this preference, Koha will calculate automatically and put that in before the values in this preference.

Descrizione:

• This preference controls the default value in the 100 field on Authority records cataloged in UNIMARC. It does not effect bibliographic records.

UseAuthoritiesForTracings

Default: Don’t use

Asks: ___ authority record numbers instead of text strings for searches from subject tracings.

Valori:

• Don’t use

  • Search links look for subject/author keywords (example: opac-search.pl?q=su:Business%20networks)

• Use

  • Search links look for an authority record (example: opac-search.pl?q=an:354)

Descrizione:

• For libraries that have authority files, they may want to make it so that when a link to an authorized subject or author is clicked on the OPAC or staff client it takes the searcher only to a list of results with that authority record. Most libraries do not have complete authority files and so setting this preference to “Don’t use” will allow searchers to click on links to authors and subject headings and perform a keyword search against those fields, finding all possible relevant results instead.

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.

Valori:

• Do

• Do not

Descrizione:

• 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.

Valori:

• Do

• Do not

Descrizione:

• 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.

Valori:

• 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

Descrizione:

• 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 ___

Importante

This feature is experimental and shouldn’t be used in a production environment until further expanded upon.

Descrizione:

• 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.

Valori:

• Do

• Do not

Descrizione:

• 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.
