 156 C4::Biblio - cataloging management functions
 157
 158 =head1 DESCRIPTION
 159
 160 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:
 161
 162 =over 4
 163
 164 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 165
 166 =item 2. as raw MARC in the Zebra index and storage engine
 167
 168 =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
 169
 170 =back
 171
 172 In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
 173
 174 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.
 175
 176 =over 4
 177
 178 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 179
 180 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 181
 182 =back
 183
 184 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:
 185
 186 =over 4
 187
 188 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 189
 190 =item 2. _koha_* - low-level internal functions for managing the koha tables
 191
 192 =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.
 193
 194 =item 4. Zebra functions used to update the Zebra index
 195
 196 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 197
 198 =back
 199
 200 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 :
 201
 202 =over 4
 203
 204 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 205
 206 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 207
 208 =item 3. save the marc record
 209
 210 =back
 211
 212 When dealing with items, we must :
 213
 214 =over 4
 215
 216 =item 1. save the item in items table, that gives us an itemnumber
 217
 218 =item 2. add the itemnumber to the item MARC field
 219
 220 =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
 221
 222 When modifying a biblio or an item, the behaviour is quite similar.

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

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

2616
2617   items.cn_source & biblioitems.cn_source
2618   items.cn_sort & biblioitems.cn_sort

2620 Columns that are currently NOT distinguished (FIXME
2621 due to lack of time to fully test) are:
2622
2623   biblio.notes and biblioitems.notes
2624   biblionumber
2625   timestamp
2626   biblioitemnumber
2627
2628 FIXME - this is necessary because prefixing each column
2629 name with the table name would require changing lots
2630 of code and templates, and exposing more of the DB
2631 structure than is good to the UI templates, particularly
2632 since biblio and bibloitems may well merge in a future
2633 version.  In the future, it would also be good to
