 150 C4::Biblio - cataloging management functions
 151
 152 =head1 DESCRIPTION
 153
 154 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:
 155
 156 =over 4
 157
 158 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 159
 160 =item 2. as raw MARC in the Zebra index and storage engine
 161
 162 =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
 163
 164 =back
 165
 166 In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
 167
 168 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.
 169
 170 =over 4
 171
 172 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 173
 174 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 175
 176 =back
 177
 178 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:
 179
 180 =over 4
 181
 182 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 183
 184 =item 2. _koha_* - low-level internal functions for managing the koha tables
 185
 186 =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.
 187
 188 =item 4. Zebra functions used to update the Zebra index
 189
 190 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 191
 192 =back
 193
 194 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 :
 195
 196 =over 4
 197
 198 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 199
 200 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 201
 202 =item 3. save the marc record
 203
 204 =back
 205
 206 When dealing with items, we must :
 207
 208 =over 4
 209
 210 =item 1. save the item in items table, that gives us an itemnumber
 211
 212 =item 2. add the itemnumber to the item MARC field
 213
 214 =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
 215
 216 When modifying a biblio or an item, the behaviour is quite similar.

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

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

 518 object C<$marc>, looking for a matching authority record,

2738
2739   items.cn_source & biblioitems.cn_source
2740   items.cn_sort & biblioitems.cn_sort

2742 Columns that are currently NOT distinguished (FIXME

2745   biblio.notes and biblioitems.notes
2746   biblionumber

2748   biblioitemnumber
2749
2750 FIXME - this is necessary because prefixing each column
2751 name with the table name would require changing lots
2752 of code and templates, and exposing more of the DB
2753 structure than is good to the UI templates, particularly
2754 since biblio and bibloitems may well merge in a future
2755 version.  In the future, it would also be good to
2756 separate DB access and UI presentation field names
2757 more.
