 115
 116 C4::Biblio - cataloging management functions
 117
 118 =head1 DESCRIPTION
 119
 120 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:
 121
 122 =over 4
 123
 124 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 125
 126 =item 2. as raw MARC in the Zebra index and storage engine
 127
 128 =item 3. as MARC XML in biblio_metadata.metadata
 129
 130 =back
 131
 132 In the 3.0 version of Koha, the authoritative record-level information is in biblio_metadata.metadata
 133
 134 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.
 135
 136 =over 4
 137
 138 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 139
 140 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 141
 142 =back
 143
 144 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:
 145
 146 =over 4
 147
 148 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 149
 150 =item 2. _koha_* - low-level internal functions for managing the koha tables
 151
 152 =item 3. Marc management function : as the MARC record is stored in biblio_metadata.metadata, 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.
 153
 154 =item 4. Zebra functions used to update the Zebra index
 155
 156 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 157
 158 =back
 159
 160 The MARC record (in biblio_metadata.metadata) 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 :
 161
 162 =over 4
 163
 164 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 165
 166 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 167
 168 =item 3. save the marc record
 169
 170 =back
 171
 172 =head1 EXPORTED FUNCTIONS
 173
 174 =head2 AddBiblio
 175
 176   ($biblionumber,$biblioitemnumber) = AddBiblio($record,$frameworkcode);
 177
 178 Exported function (core API) for adding a new biblio to koha.
 179
 180 The first argument is a C<MARC::Record> object containing the
 181 bib to add, while the second argument is the desired MARC
 182 framework code.
 183
 184 This function also accepts a third, optional argument: a hashref
 185 to additional options.  The only defined option is C<defer_marc_save>,
 186 which if present and mapped to a true value, causes C<AddBiblio>
 187 to omit the call to save the MARC in C<biblio_metadata.metadata>
 188 This option is provided B<only>
 189 for the use of scripts such as C<bulkmarcimport.pl> that may need
 190 to do some manipulation of the MARC record for item parsing before
 191 saving it and which cannot afford the performance hit of saving
 192 the MARC record twice.  Consequently, do not use that option
 193 unless you can guarantee that C<ModBiblioMarc> will be called.

 244
 245 Replace an existing bib record identified by C<$biblionumber>
 246 with one supplied by the MARC::Record object C<$record>.  The embedded
 247 item, biblioitem, and biblionumber fields from the previous
 248 version of the bib record replace any such fields of those tags that
 249 are present in C<$record>.  Consequently, ModBiblio() is not
 250 to be used to try to modify item records.
 251
 252 C<$frameworkcode> specifies the MARC framework to use
 253 when storing the modified bib record; among other things,
 254 this controls how MARC fields get mapped to display columns
 255 in the C<biblio> and C<biblioitems> tables, as well as
 256 which fields are used to store embedded item, biblioitem,
 257 and biblionumber data for indexing.

2596 Columns that are currently NOT distinguished (FIXME
2597 due to lack of time to fully test) are:
2598
2599   biblio.notes and biblioitems.notes
2600   biblionumber
2601   timestamp
2602   biblioitemnumber
2603
2604 FIXME - this is necessary because prefixing each column
2605 name with the table name would require changing lots
2606 of code and templates, and exposing more of the DB
2607 structure than is good to the UI templates, particularly
2608 since biblio and bibloitems may well merge in a future
2609 version.  In the future, it would also be good to
2610 separate DB access and UI presentation field names
2611 more.
