 118 C4::Biblio - cataloging management functions
 119
 120 =head1 DESCRIPTION
 121
 122 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:
 123
 124 =over 4
 125
 126 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
 127
 128 =item 2. as raw MARC in the Zebra index and storage engine
 129
 130 =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml
 131
 132 =back
 133
 134 In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml
 135
 136 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.
 137
 138 =over 4
 139
 140 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
 141
 142 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
 143
 144 =back
 145
 146 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:
 147
 148 =over 4
 149
 150 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
 151
 152 =item 2. _koha_* - low-level internal functions for managing the koha tables
 153
 154 =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.
 155
 156 =item 4. Zebra functions used to update the Zebra index
 157
 158 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
 159
 160 =back
 161
 162 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 :
 163
 164 =over 4
 165
 166 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
 167
 168 =item 2. add the biblionumber and biblioitemnumber into the MARC records
 169
 170 =item 3. save the marc record
 171
 172 =back
 173
 174 When dealing with items, we must :
 175
 176 =over 4
 177
 178 =item 1. save the item in items table, that gives us an itemnumber
 179
 180 =item 2. add the itemnumber to the item MARC field
 181
 182 =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml)
 183
 184 When modifying a biblio or an item, the behaviour is quite similar.

 197
 198 Exported function (core API) for adding a new biblio to koha.
 199
 200 The first argument is a C<MARC::Record> object containing the
 201 bib to add, while the second argument is the desired MARC
 202 framework code.
 203
 204 This function also accepts a third, optional argument: a hashref
 205 to additional options.  The only defined option is C<defer_marc_save>,
 206 which if present and mapped to a true value, causes C<AddBiblio>
 207 to omit the call to save the MARC in C<bibilioitems.marc>
 208 and C<biblioitems.marcxml>  This option is provided B<only>
 209 for the use of scripts such as C<bulkmarcimport.pl> that may need
 210 to do some manipulation of the MARC record for item parsing before
 211 saving it and which cannot afford the performance hit of saving
 212 the MARC record twice.  Consequently, do not use that option
 213 unless you can guarantee that C<ModBiblioMarc> will be called.

 255 Replace an existing bib record identified by C<$biblionumber>
 256 with one supplied by the MARC::Record object C<$record>.  The embedded
 257 item, biblioitem, and biblionumber fields from the previous
 258 version of the bib record replace any such fields of those tags that
 259 are present in C<$record>.  Consequently, ModBiblio() is not
 260 to be used to try to modify item records.
 261
 262 C<$frameworkcode> specifies the MARC framework to use
 263 when storing the modified bib record; among other things,
 264 this controls how MARC fields get mapped to display columns
 265 in the C<biblio> and C<biblioitems> tables, as well as
 266 which fields are used to store embedded item, biblioitem,
 267 and biblionumber data for indexing.

1732 This is a temporary hack to distinguish between the
1733 following sets of columns when using TransformMarcToKoha.
1734
1735 items.cn_source & biblioitems.cn_source
1736 items.cn_sort & biblioitems.cn_sort
1737
1738 Columns that are currently NOT distinguished (FIXME
1739 due to lack of time to fully test) are:
1740
1741 biblio.notes and biblioitems.notes
1742 biblionumber
1743 timestamp
1744 biblioitemnumber
1745
1746 FIXME - this is necessary because prefixing each column
1747 name with the table name would require changing lots
1748 of code and templates, and exposing more of the DB
1749 structure than is good to the UI templates, particularly
1750 since biblio and bibloitems may well merge in a future
1751 version.  In the future, it would also be good to
1752 separate DB access and UI presentation field names
1753 more.
