--- Comment #10 from Phil Ringnalda <[email protected]> --- Created attachment 201871 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=201871&action=edit Bug 31925: Add thesaurus/008 lookup and default MARC21 008 builder to Koha::Authority AutoCreateAuthorities builds a brand-new authority record whenever a bib subject heading (6XX) has no match, but always lets the record fall back to C4::AuthoritiesMarc::AddAuthority()'s default 008/040, which hardcodes 008 position 11 ("Subject heading system/thesaurus") to 'a' (LCSH) no matter what thesaurus the source heading actually uses. This is the first step towards fixing that. Adds two things to Koha::Authority: - $MARC21_THESAURUS_TO_CONTROL_FIELD_008_11: a single-source-of-truth lookup mapping a thesaurus name (as already derived by C4::Heading from MARC indicator 2 / subfield $2, e.g. 'lcsh', 'mesh', or a raw $2 code such as 'fast') to its MARC21 authority 008/11 code, per the LOC ad008 code list. This table previously only existed once, for a different purpose, in Koha::SearchEngine::Elasticsearch::QueryBuilder (used for building thesaurus search queries) - it's promoted here so both that and the authority-creation fix that follows can read from one place instead of two copies that can silently drift apart. - default_marc21_008($thesaurus): builds the default 34-character body of a new MARC21 authority's 008 field, honouring the MARCAuthorityControlField008 system preference. When $thesaurus is given, position 11 is set from the table above instead of whatever the default/syspref value carries, falling back to 'z' (Other) for a thesaurus with no dedicated code. AddAuthority() is refactored to build its own (thesaurus-less, LCSH default) 008 via this new method too, replacing its previous inline copy of the same defaulting logic - pure refactor, no behaviour change. Nothing thesaurus-aware calls it yet.
