 114
 115 C4::Biblio - cataloging management functions
 116
 117 =head1 DESCRIPTION
 118
 119 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:
 120
 121 =over 4
 122
 123 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 124
 125 =item 2. as raw MARC in the Zebra index and storage engine
 126
 127 =item 3. as MARC XML in biblio_metadata.metadata
 128
 129 =back
 130
 131 In the 3.0 version of Koha, the authoritative record-level information is in biblio_metadata.metadata
 132
 133 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.
 134
 135 =over 4
 136
 137 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 138
 139 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 140
 141 =back
 142
 143 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:
 144
 145 =over 4
 146
 147 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 148
 149 =item 2. _koha_* - low-level internal functions for managing the koha tables
 150
 151 =item 3. Marc management function : as the MARC record is stored in biblio_metadata.metadata, 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.
 152
 153 =item 4. Zebra functions used to update the Zebra index
 154
 155 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 156
 157 =back
 158
 159 The MARC record (in biblio_metadata.metadata) 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 :
 160
 161 =over 4
 162
 163 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 164
 165 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 166
 167 =item 3. save the marc record
 168
 169 =back
 170
 171 =head1 EXPORTED FUNCTIONS
 172
 173 =head2 AddBiblio
 174
 175   ($biblionumber,$biblioitemnumber) = AddBiblio($record,$frameworkcode);
 176
 177 Exported function (core API) for adding a new biblio to koha.
 178
 179 The first argument is a C<MARC::Record> object containing the
 180 bib to add, while the second argument is the desired MARC
 181 framework code.
 182
 183 This function also accepts a third, optional argument: a hashref
 184 to additional options.  The only defined option is C<defer_marc_save>,
 185 which if present and mapped to a true value, causes C<AddBiblio>
 186 to omit the call to save the MARC in C<biblio_metadata.metadata>
 187 This option is provided B<only>
 188 for the use of scripts such as C<bulkmarcimport.pl> that may need
 189 to do some manipulation of the MARC record for item parsing before
 190 saving it and which cannot afford the performance hit of saving
 191 the MARC record twice.  Consequently, do not use that option
 192 unless you can guarantee that C<ModBiblioMarc> will be called.

 243
 244   ModBiblio( $record,$biblionumber,$frameworkcode, $disable_autolink);
 245
 246 Replace an existing bib record identified by C<$biblionumber>
 247 with one supplied by the MARC::Record object C<$record>.  The embedded
 248 item, biblioitem, and biblionumber fields from the previous
 249 version of the bib record replace any such fields of those tags that
 250 are present in C<$record>.  Consequently, ModBiblio() is not
 251 to be used to try to modify item records.
 252
 253 C<$frameworkcode> specifies the MARC framework to use
 254 when storing the modified bib record; among other things,
 255 this controls how MARC fields get mapped to display columns
 256 in the C<biblio> and C<biblioitems> tables, as well as
 257 which fields are used to store embedded item, biblioitem,
 258 and biblionumber data for indexing.
 259
 260 Unless C<$disable_autolink> is passed ModBiblio will relink record headings
 261 to authorities based on settings in the system preferences. This flag allows
 262 us to not relink records when the authority linker is saving modifications.
 263
 264 Returns 1 on success 0 on failure
