120 C4::Biblio - cataloging management functions
124 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:
128 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
130 =item 2. as raw MARC in the Zebra index and storage engine
132 =item 3. as MARC XML in biblio_metadata.metadata
136 In the 3.0 version of Koha, the authoritative record-level information is in biblio_metadata.metadata
138 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.
142 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
144 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
148 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:
152 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
154 =item 2. _koha_* - low-level internal functions for managing the koha tables
156 =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.
158 =item 4. Zebra functions used to update the Zebra index
160 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
164 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 :
168 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
170 =item 2. add the biblionumber and biblioitemnumber into the MARC records
172 =item 3. save the marc record

320 with one supplied by the MARC::Record object C<$record>. The embedded
321 item, biblioitem, and biblionumber fields from the previous
322 version of the bib record replace any such fields of those tags that
323 are present in C<$record>. Consequently, ModBiblio() is not
324 to be used to try to modify item records.
326 C<$frameworkcode> specifies the MARC framework to use
327 when storing the modified bib record; among other things,
328 this controls how MARC fields get mapped to display columns
329 in the C<biblio> and C<biblioitems> tables, as well as
330 which fields are used to store embedded item, biblioitem,
331 and biblionumber data for indexing.
333 The C<$options> argument is a hashref with additional parameters:
337 =item C<overlay_context>
339 This parameter is forwarded to L</ApplyMarcOverlayRules> where it is used for
340 selecting the current rule set if MARCOverlayRules is enabled.
341 See L</ApplyMarcOverlayRules> for more details.
343 =item C<disable_autolink>
345 Unless C<disable_autolink> is passed ModBiblio will relink record headings
346 to authorities based on settings in the system preferences. This flag allows
347 us to not relink records when the authority linker is saving modifications.
349 =item C<skip_holds_queue>
351 Unless C<skip_holds_queue> is passed, ModBiblio will trigger the BatchUpdateBiblioHoldsQueue
352 task to rebuild the holds queue for the biblio if I<RealTimeHoldsQueue> is enabled.
