121 C4::Biblio - cataloging management functions
125 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:
129 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data
131 =item 2. as raw MARC in the Zebra index and storage engine
133 =item 3. as MARC XML in biblio_metadata.metadata
137 In the 3.0 version of Koha, the authoritative record-level information is in biblio_metadata.metadata
139 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.
143 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation
145 =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases
149 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:
153 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection
155 =item 2. _koha_* - low-level internal functions for managing the koha tables
157 =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.
159 =item 4. Zebra functions used to update the Zebra index
161 =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm
165 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 :
169 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber
171 =item 2. add the biblionumber and biblioitemnumber into the MARC records
173 =item 3. save the marc record

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