 146 C4::Biblio - cataloging management functions
 147
 148 =head1 DESCRIPTION
 149
 150 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:
 151
 152 =over 4
 153
 154 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 155
 156 =item 2. as raw MARC in the Zebra index and storage engine
 157
 158 =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
 159
 160 =back
 161
 162 In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
 163
 164 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.
 165
 166 =over 4
 167
 168 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 169
 170 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 171
 172 =back
 173
 174 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:
 175
 176 =over 4
 177
 178 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 179
 180 =item 2. _koha_* - low-level internal functions for managing the koha tables
 181
 182 =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.
 183
 184 =item 4. Zebra functions used to update the Zebra index
 185
 186 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 187
 188 =back
 189
 190 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 :
 191
 192 =over 4
 193
 194 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 195
 196 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 197
 198 =item 3. save the marc record
 199
 200 =back
 201
 202 When dealing with items, we must :
 203
 204 =over 4
 205
 206 =item 1. save the item in items table, that gives us an itemnumber
 207
 208 =item 2. add the itemnumber to the item MARC field
 209
 210 =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
 211
 212 When modifying a biblio or an item, the behaviour is quite similar.

 218 =head2 AddBiblio
 219
 220   ($biblionumber,$biblioitemnumber) = AddBiblio($record,$frameworkcode);
 221
 222 Exported function (core API) for adding a new biblio to koha.
 223
 224 The first argument is a C<MARC::Record> object containing the
 225 bib to add, while the second argument is the desired MARC
 226 framework code.
 227
 228 This function also accepts a third, optional argument: a hashref
 229 to additional options.  The only defined option is C<defer_marc_save>,
 230 which if present and mapped to a true value, causes C<AddBiblio>
 231 to omit the call to save the MARC in C<bibilioitems.marc>
 232 and C<biblioitems.marcxml>  This option is provided B<only>
 233 for the use of scripts such as C<bulkmarcimport.pl> that may need
 234 to do some manipulation of the MARC record for item parsing before
 235 saving it and which cannot afford the performance hit of saving
 236 the MARC record twice.  Consequently, do not use that option
 237 unless you can guarantee that C<ModBiblioMarc> will be called.

 282
 283   ModBiblio( $record,$biblionumber,$frameworkcode);
 284
 285 Replace an existing bib record identified by C<$biblionumber>
 286 with one supplied by the MARC::Record object C<$record>.  The embedded
 287 item, biblioitem, and biblionumber fields from the previous
 288 version of the bib record replace any such fields of those tags that
 289 are present in C<$record>.  Consequently, ModBiblio() is not
 290 to be used to try to modify item records.
 291
 292 C<$frameworkcode> specifies the MARC framework to use
 293 when storing the modified bib record; among other things,
 294 this controls how MARC fields get mapped to display columns
 295 in the C<biblio> and C<biblioitems> tables, as well as
 296 which fields are used to store embedded item, biblioitem,
 297 and biblionumber data for indexing.

2705 FIXME - this is necessary because prefixing each column
2706 name with the table name would require changing lots
2707 of code and templates, and exposing more of the DB
2708 structure than is good to the UI templates, particularly
2709 since biblio and bibloitems may well merge in a future
2710 version.  In the future, it would also be good to
2711 separate DB access and UI presentation field names
