=head1 NAME
C4::Biblio - cataloging management functions
=head1 DESCRIPTION
Biblio.pm contains functions for managing storage and editing of bibliographic data within Koha. Most of the functions in this module are used for cataloging records: adding, editing, or removing biblios, biblioitems, or items. Koha's stores bibliographic information in three places:
=over 4
=item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
=item 2. as raw MARC in the Zebra index and storage engine
=item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
=back
In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
Because the data isn't completely normalized there's a chance for information to get out of sync. The design choice to go with a un-normalized schema was driven by performance and stability concerns. However, if this occur, it can be considered as a bug : The API is (or should be) complete & the only entry point for all biblio/items managements.
=over 4
=item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
=item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
=back
Because of this design choice, the process of managing storage and editing is a bit convoluted. Historically, Biblio.pm's grown to an unmanagable size and as a result we have several types of functions currently:
=over 4
=item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
=item 2. _koha_* - low-level internal functions for managing the koha tables
=item 3. Marc management function : as the MARC record is stored in biblioitems.marc(xml), some subs dedicated to it's management are in this package. They should be used only internally by Biblio.pm, the only official entry points being AddBiblio, AddItem, ModBiblio, ModItem.
=item 4. Zebra functions used to update the Zebra index
=item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
=back
The MARC record (in biblioitems.marcxml) contains the complete marc record, including items. It also contains the biblionumber. That is the reason why it is not stored directly by AddBiblio, with all other fields . To save a biblio, we need to :
=over 4
=item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
=item 2. add the biblionumber and biblioitemnumber into the MARC records
=item 3. save the marc record
=back
When dealing with items, we must :
=over 4
=item 1. save the item in items table, that gives us an itemnumber
=item 2. add the itemnumber to the item MARC field
=item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
When modifying a biblio or an item, the behaviour is quite similar.
=back
=head1 EXPORTED FUNCTIONS
=head2 AddBiblio
($biblionumber,$biblioitemnumber) = AddBiblio($record,$frameworkcode);
Exported function (core API) for adding a new biblio to koha.
The first argument is a C<MARC::Record> object containing the
bib to add, while the second argument is the desired MARC
framework code.
This function also accepts a third, optional argument: a hashref
to additional options. The only defined option is C<defer_marc_save>,
which if present and mapped to a true value, causes C<AddBiblio>
to omit the call to save the MARC in C<bibilioitems.marc>
and C<biblioitems.marcxml> This option is provided B<only>
for the use of scripts such as C<bulkmarcimport.pl> that may need
to do some manipulation of the MARC record for item parsing before
saving it and which cannot afford the performance hit of saving
the MARC record twice. Consequently, do not use that option
unless you can guarantee that C<ModBiblioMarc> will be called.

ModBiblio( $record,$biblionumber,$frameworkcode);
Replace an existing bib record identified by C<$biblionumber>
with one supplied by the MARC::Record object C<$record>. The embedded
item, biblioitem, and biblionumber fields from the previous
version of the bib record replace any such fields of those tags that
are present in C<$record>. Consequently, ModBiblio() is not
to be used to try to modify item records.
C<$frameworkcode> specifies the MARC framework to use
when storing the modified bib record; among other things,
this controls how MARC fields get mapped to display columns
in the C<biblio> and C<biblioitems> tables, as well as
which fields are used to store embedded item, biblioitem,
and biblionumber data for indexing.

=head2 _disambiguate
$newkey = _disambiguate($table, $field);
This is a temporary hack to distinguish between the
following sets of columns when using TransformMarcToKoha.
items.cn_source & biblioitems.cn_source
items.cn_sort & biblioitems.cn_sort
Columns that are currently NOT distinguished (FIXME
due to lack of time to fully test) are:
biblio.notes and biblioitems.notes
biblionumber
timestamp
biblioitemnumber
FIXME - this is necessary because prefixing each column
name with the table name would require changing lots
of code and templates, and exposing more of the DB
structure than is good to the UI templates, particularly
since biblio and bibloitems may well merge in a future
version. In the future, it would also be good to
separate DB access and UI presentation field names
more.
