>Subject: [PATCH] Bug 38142: Choose language to report from authority to
> bibliographic record.
>MIME-Version: 1.0
>Content-Type: text/plain; charset=UTF-8
>Content-Transfer-Encoding: 8bit
>
>Currently, when reporting authority field to the bibliographic records,
>the merge function uses the first matching authority field.
>
>However, authorities can provide multiple versions of the same field, with
>different languages, identified by a code in the $7 field.
>
>French reference for languages codes for example, but any code system could be
>used:
>https://documentation.abes.fr/sudoc/formats/unmb/DonneesCodees/CodesZone104.htm#$d
>
>This patch introduces the LanguageToReportOnMerge system preference, which
>allows to specify a language code.
>
>When set, if there is an authority field with the given language code, it will
>be used to report to the bibliographic record.
>
>If the system preference is not set, or there is no matching field, the default
>behavior will apply: the first field will be used.
>
>The $7 in the authority field can be in a short or long form:
>
> - the short form is 2 characters long. Example: ba
> - the long form is 8 characters long, with the short form in position 5 and 6
>   (starting from 1). Example: ba0yba0y
>
>Test plan:
>----------
>
>1) Edit the 'Personal Name' authority type framework to make the 100 field
>repeatable
>
>2) Add an authority with several languages, like this (the order is important):
>
>100    _7ba0yda0y
>       _aä¼æ±è±é
>100    _7ba0yba0y
>       _aItÅ
>
>3) Add a bibliographic record linked to that authority.
>(Click on the "tag editor" icon next to the 100$a field in the bibliographic record to
> search for the authority, then Search main heading ($a only): contains ItÅ)
>
>Note that you can choose which version you want when searching for the
>authority, under the "Get it!" column
>
>For this example, choose the latin version: ItÅ
>
>You should now have this in your bibliographic record:
>100    _aItÅ
>       _92646
>
>4) Edit the authority, you don't have to change anything, just edit and save.
>Note that your bibliographic record now looks like this:
>
>100    _7ba0yda0y
>       _aä¼æ±è±é
>       _92646
>
>The first 100 field of the authority has been reported back to the bibliographic
>record, regardless of what you chose when selecting the authority.
>
>5) Apply the patch, set the LanguageToReportOnMerge system preference to: 'ba'
>
>6) Edit the authority again, and check that your bibliographic record now looks
>like this, according to the system preference:
>
>100    _7ba0yba0y
>       _aItÅ
>       _92646
>
>7) Edit the authority again, but set the $7 of the latin field to its short
>form:
>
>100    _7ba0yda0y
>       _aä¼æ±è±é
>100    _7ba
>       _aItÅ
>
>8) Check that the bibliographic record still has the latin field reported:
>
>100    _7ba
>       _aItÅ
>       _92646
>
>9) prove koha/t/db_dependent/Authority/Merge.t
>
>10) Sign-off :)
