-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.

 ===== Authority Index =====
-The authority index lives alongside the bib index within VuFind's Solr instance to store Authority records.
+The authority index lives alongside the bib index within VuFind®'s Solr instance to store Authority records.
 The field schema is structured as follows:
 ^ Field ^ Value ^
 | id | control number |
-| fullrecord | full MARC authority record |
+| record_format | record format (used to load the appropriate [[development:plugins:record_drivers|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 MARC fields to augment searching |

 | record_type | type of authority record (i.e. Personal Name, Corporate Name, etc. |
 | lccn | Library of Congress card number for authority record |

 | scope_note | Scope note |
 | heading_keywords / use_for_keywords / see_also_keywords | Copy-fielded versions of heading / use_for / see_also used in full-text searching |

+The authority schema also supports the [[solr_index_schema#dynamic_field_suffixes|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.
-===== Obtaining Authority Records =====
+==== Changelog ====
-In addition to exporting records from your ILS, you may be able to load them from public sources.
+=== Version 5.0 ===
+Changed "allfields" to multi-valued and added institution and record_format fields.
+=== Version 3.1 ===
-==== Loading OCLC FAST Records ====
+Added birth_date / death_date / birth_place / death_place / country / related_place / field_of_activity / occupation / gender / language fields.
-There used to be an OCLC API for loading the LC Name Authority File, and VuFind 1.x included a tool for importing records from this API; as of this writing, that service is no longer available, and the FAST names are a preferable data source.
+=== Version 1.1 ===
-See the [[indexing:open_data_sources#oclc_fast|OCLC Fast]] section of the [[indexing:open_data_sources|Open Data Sources]] page for details on importing free authority records from OCLC.
+Authority system introduced.
-===== Authority Import Script =====
+===== Obtaining Authority Records =====
-VuFind has a separate indexing script that uses [[indexing:solrmarc|SolrMarc]] to load authority records into the authority index.  See [[:indexing:marc#importing_authority_records|Importing Authority Records]] for more details.
+In addition to exporting records from your ILS, you may be able to load them from public sources.
-===== Bibliographic Records =====
+==== Loading OCLC FAST Records ====
-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 [[indexing:alphabetical_heading_browse|Alphabetical Heading Browse]] takes advantage of authority data.  It is also possible to implement [[:development:plugins:recommendation_modules|Recommendations Modules]] and/or [[:autocomplete#building_custom_suggestions|Custom Autosuggestions]] to take advantage of authority data, though this work is not yet complete.

It is also possible to implement additional [[:development:plugins:recommendation_modules|Recommendations Modules]] and/or [[configuration:autocomplete#building_custom_suggestions|Custom Autosuggestions]] to take advantage of authority data.
