 144
 145 C4::Biblio - cataloging management functions
 146
 147 =head1 DESCRIPTION
 148
 149 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:
 150
 151 =over 4
 152
 153 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 154
 155 =item 2. as raw MARC in the Zebra index and storage engine
 156
 157 =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
 158
 159 =back
 160
 161 In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
 162
 163 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.
 164
 165 =over 4
 166
 167 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 168
 169 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 170
 171 =back
 172
 173 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:
 174
 175 =over 4
 176
 177 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 178
 179 =item 2. _koha_* - low-level internal functions for managing the koha tables
 180
 181 =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.
 182
 183 =item 4. Zebra functions used to update the Zebra index
 184
 185 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 186
 187 =back
 188
 189 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 :
 190
 191 =over 4
 192
 193 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 194
 195 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 196
 197 =item 3. save the marc record
 198
 199 =back
 200
 201 When dealing with items, we must :
 202
 203 =over 4
 204
 205 =item 1. save the item in items table, that gives us an itemnumber
 206
 207 =item 2. add the itemnumber to the item MARC field
 208
 209 =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
 210
 211 When modifying a biblio or an item, the behaviour is quite similar.

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

 275 Replace an existing bib record identified by C<$biblionumber>
 276 with one supplied by the MARC::Record object C<$record>.  The embedded
 277 item, biblioitem, and biblionumber fields from the previous
 278 version of the bib record replace any such fields of those tags that
 279 are present in C<$record>.  Consequently, ModBiblio() is not
 280 to be used to try to modify item records.
 281
 282 C<$frameworkcode> specifies the MARC framework to use
 283 when storing the modified bib record; among other things,
 284 this controls how MARC fields get mapped to display columns
 285 in the C<biblio> and C<biblioitems> tables, as well as
 286 which fields are used to store embedded item, biblioitem,
 287 and biblionumber data for indexing.

2131 name with the table name would require changing lots
2132 of code and templates, and exposing more of the DB
2133 structure than is good to the UI templates, particularly
2134 since biblio and bibloitems may well merge in a future
2135 version.  In the future, it would also be good to
2136 separate DB access and UI presentation field names
