Authority Control in VuFind
Starting with version 1.1, VuFind includes an authority control system. This page provides some details on how it is being used and how its application could be expanded.
The authority index lives alongside the bib index within VuFind's Solr instance to store Authority records.
The field schema is structured as follows:
|record_format||record format (used to load the appropriate record driver – prefixed with “SolrAuth” to create a service alias). Added in release 5.0; prior to that, all authority records were assumed to be MARC.|
|fullrecord||full authority record in raw form (usually MARC, but see record_format)|
|marc_error||errors reported by the SolrMarc import tool|
|allfields||content of all human-readable fields in the authority record, used to augment searching|
|source||source of the authority record (i.e. Library of Congress Name Authority File, Local System, etc.)|
|institution||institution controlling authority record; potentially useful for faceting. Added in release 5.0.|
|record_type||type of authority record (i.e. Personal Name, Corporate Name, etc.|
|lccn||Library of Congress card number for authority record|
|heading||Primary legal heading for authority record (i.e. 1XX field)|
|use_for||Variant names for authority record (i.e. 4XX fields)|
|see_also||Related authority records (i.e. 5XX fields)|
|heading_keywords / use_for_keywords / see_also_keywords||Copy-fielded versions of heading / use_for / see_also used in full-text searching|
|birth_date / death_date / birth_place / death_place / country / related_place / field_of_activity / occupation / gender / language||Fields for storing data added in RDA to describe people; used primarily for faceting. Added in release 3.1.|
|first_indexed / last_indexed||Index dates used for tracking record changes|
The authority schema also supports the dynamic field suffixes _date, _date_mv, _str, _str_mv, _txt, and _txt_mv. Some of VuFind's default import configurations take advantages of these suffixes to index some additional facet fields: chronological_facet_str_mv, form_facet_str_mv, general_facet_str_mv and geographic_facet_str_mv.
Changed “allfields” to multi-valued and added institution and record_format fields.
Added birth_date / death_date / birth_place / death_place / country / related_place / field_of_activity / occupation / gender / language fields.
Obtaining Authority Records
In addition to exporting records from your ILS, you may be able to load them from public sources.

Authority Import Script
Authority records are not currently explicitly referenced inside VuFind's bibliographic Solr index – it is assumed that authority processing is done externally and that bib records contain consistent headings. It may be worth doing some additional work to store authorized and item-specific forms of headings in the Solr “biblio” index to allow more precise searching.
Separate search systems have been created to allow author searching and browsing. VuFind has a simple Authority module that allows searching of the authority index, and the Alphabetical Heading Browse takes advantage of authority data. The existing AuthorityRecommend recommendation module offers a simple mechanism for suggesting alternate searches based on authority data. It is also possible to implement additional Recommendations Modules and/or Custom Autosuggestions to take advantage of authority data.
