 152
 153 C4::Biblio - cataloging management functions
 154
 155 =head1 DESCRIPTION
 156
 157 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:
 158
 159 =over 4
 160
 161 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 162
 163 =item 2. as raw MARC in the Zebra index and storage engine
 164
 165 =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
 166
 167 =back
 168
 169 In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
 170
 171 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.
 172
 173 =over 4
 174
 175 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 176
 177 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 178
 179 =back
 180
 181 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:
 182
 183 =over 4
 184
 185 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 186
 187 =item 2. _koha_* - low-level internal functions for managing the koha tables
 188
 189 =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.
 190
 191 =item 4. Zebra functions used to update the Zebra index
 192
 193 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 194
 195 =back
 196
 197 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 :
 198
 199 =over 4
 200
 201 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 202
 203 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 204
 205 =item 3. save the marc record
 206
 207 =back
 208
 209 When dealing with items, we must :
 210
 211 =over 4
 212
 213 =item 1. save the item in items table, that gives us an itemnumber
 214
 215 =item 2. add the itemnumber to the item MARC field
 216
 217 =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
 218
 219 When modifying a biblio or an item, the behaviour is quite similar.

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

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

 519 Links bib headings to authority records by checking

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

 525 If $allowrelink is false, existing authids will never be

2707 FIXME - this is necessary because prefixing each column
2708 name with the table name would require changing lots
2709 of code and templates, and exposing more of the DB
2710 structure than is good to the UI templates, particularly
2711 since biblio and bibloitems may well merge in a future
2712 version.  In the future, it would also be good to
2713 separate DB access and UI presentation field names
