Currently, MARC authorities are indexed (assuming Zebra
is used) with Zebra's GRS-1 module. However, it does
not appear to be possible to index phrases that cross
subfield boundaries using the GRS-1 module's records.abs
config file's melm, elm, and xelm directives.
Since it is necessary to be able to efficiently search
an entire authority heading (e.g., to see if a given
bib heading is authorized), I'm proposing a switch
to Zebra's DOM XML filter module, which uses XSLT
to generate the words and phrases to be indexed from the
original MARC XML (or ISO2709) record.
The file authority-zebra-indexdefs.xml is an XSLT stylesheet
to implement the new indexing regime. It is based on the
MARC21 authority record.abs with the following changes:
* addition of 148/448/548
* changed name of "see" indexes to "see-from"
* changed name of "see-also" indexes to "see-also-from"
* added index on the subject thesaurus based on
the 008/11 and 040$f
* added indexes on the full heading
authority-zebra-indexdefs.xml was generated from
authority-koha-indexdefs.xml via the XSL transform
koha-indexdefs-to-zebra.xsl. authority-koha-indexdefs.xml
is the actual master version of the indexing definitions,
and was created to provide a much more compact syntax
over the raw XSLT that is to be passed to Zebra.
An experimental schema for Koha indexing definitions is
under way; my aim is to propose a simple format that can
be readily worked with, and perhaps even generated as
a serialization of indexing definitions that are set up
via administration settings in the Koha database itself.

* Defined local field 942$a to store the authority type
for MARC21 instead of 152$b
* Added 942$b to MARC21 authority framework.
* Added auth_header.authid and auth_header.authtypecode
to appropriate subfields in MARC21 authority framework.
* Started work on two new modules:
C4::AuthoritiesMarc::MARC21
C4::AuthoritiesMarc::UNIMARC
These modules will be used to extract MARC-format-specific
behavior out of C4::AuthoritiesMarc
* Updated Zebra config for MARC21 to use only the 942$a
for the authority type.
* For MARC21, added logic to move 152$b to 942$a for
existing authority records. Specifically, AddAuthority
now does this move when a record is saved, while
GetAuthority and GetAuthorityXML do this when
extracting a record for other use. This logic
is temporary, and can hopefully be removed later, once
use of 152$b in MARC21 authorities is confirmed to be
absent for Koha users. I will also create a batch
job to do this update in one fell swoop.

This commit is a partial fix to authority control for MARC21,
and better authority handling in general (for UNIMARC too).
Before this patch, authority searching, editing, saving, was
not functioning, or was extremely buggy.
WARNING: You will need to re-index your authority database after
applying this commit.
The following changes have been made:
* Normalizing record.abs index names (in both MARC21 and UNIMARC)
* Synching authorities/bib1.att, ccl.properties, AuthoritiesMarc.pm
with new indexes (UNIMARC too)
* Clean up biblios/bib1.att (remove duplicate att defs)
* Clean up authorities-* templates to conform to new styles
* Fixed search failure when using Default framework (now searches
All)
Also included are several fixes to the built-in SRU server for
Authority and Biblio, it's recommended that you update your
koha-conf.xml file:
* adding explain-authorities.xml and explain-biblios.xml
* adding necessary info to koha-conf.xml to enable SRU/W
* adding several example XSLT stylesheets, that can be used
for SRU on-the-fly transformations (to MODS, DC, RDF, etc.)
Still remaining for 3.0 are the following tasks:
* update MARC21 frameworks (authority and cross-reference bib)
* update display code/templates in authority results list
* update search code/templates to utilize index points
* implement 'grouping' of authtypes for searching (Name, Title, Subject)
* repair utility to import auths and perform matching
* repair bibliographic import to match auths and warn if no match

* prior to this commit, virtual shelvesn't did not function in
the OPAC! Now they do, except for deletion from virtual shelves
in list form
* I've re-named 'Virtual Shelves' to 'Lists' as per our agreed
upon convention
* while vshelves aren't perfect yet, they're in enough of a working
state for the RC1 now

All Zebra config files are now installed by default. The
ones specific to a MARC format or language are selected
by appropriate values in profilePath in zebra-biblios.cfg
and zebra-authorities.cfg. Changing the MARC format
or indexing language can now be done by editing
profilePath.
Inspired by work by Chris Cormack, move several base Zebra
configuration files to two new directories under etc/zebradb:
lang_defs - language-specific settings (e.g., French and English)
marc_defs - MARC format-specific settings (e.g., MARC21 & UNIMARC)
Installer will query user for language and MARC format and
copy the inital Zebra configs accordingly.
