  97 C4::Items - item management functions
  98
  99 =head1 DESCRIPTION
 100
 101 This module contains an API for manipulating item
 102 records in Koha, and is used by cataloguing, circulation,
 103 acquisitions, and serials management.
 104
 105 A Koha item record is stored in two places: the
 106 items table and embedded in a MARC tag in the XML
 107 version of the associated bib record in C<biblioitems.marcxml>.
 108 This is done to allow the item information to be readily
 109 indexed (e.g., by Zebra), but means that each item
 110 modification transaction must keep the items table
 111 and the MARC XML in sync at all times.
 112
 113 Consequently, all code that creates, modifies, or deletes
 114 item records B<must> use an appropriate function from
 115 C<C4::Items>.  If no existing function is suitable, it is
 116 better to add one to C<C4::Items> than to use add
 117 one-off SQL statements to add or modify items.
 118
 119 The items table will be considered authoritative.  In other
 120 words, if there is ever a discrepancy between the items
 121 table and the MARC XML, the items table should be considered
 122 accurate.
 123
 124 =head1 HISTORICAL NOTE
 125
 126 Most of the functions in C<C4::Items> were originally in
 127 the C<C4::Biblio> module.
 128
 129 =head1 CORE EXPORTED FUNCTIONS
 130
 131 The following functions are meant for use by users
 132 of C<C4::Items>

 136 =head2 GetItem
 137
 138   $item = GetItem($itemnumber,$barcode,$serial);
 139
 140 Return item information, for a given itemnumber or barcode.
 141 The return value is a hashref mapping item column
 142 names to values.  If C<$serial> is true, include serial publication data.

 186 Set the current shelving location of the item record
 187 to its stored permanent shelving location.  This is
 188 primarily used to indicate when an item whose current
 189 location is a special processing ('PROC') or shelving cart
 190 ('CART') location is back in the stacks.

 232       = AddItemFromMarc($source_item_marc, $biblionumber);

 235 record and a biblionumber, create a new item record.

 259 Given a hash containing item column names as keys,
 260 create a new Koha item record.
 261
 262 The first two optional parameters (C<$dbh> and C<$frameworkcode>)
 263 do not need to be supplied for general use; they exist
 264 simply to allow them to be picked up from AddItemFromMarc.
 265
 266 The final optional parameter, C<$unlinked_item_subfields>, contains
 267 an arrayref containing subfields present in the original MARC
 268 representation of the item (e.g., from the item editor) that are
 269 not mapped to C<items> columns directly but should instead
 270 be stored in C<items.more_subfields_xml> and included in
 271 the biblio items tag for display and indexing.

 316
 317 Efficiently create item records from a MARC biblio record with
 318 embedded item fields.  This routine is suitable for batch jobs.
 319
 320 This API assumes that the bib record has already been
 321 saved to the C<biblio> and C<biblioitems> tables.  It does
 322 not expect that C<biblioitems.marc> and C<biblioitems.marcxml>
 323 are populated, but it will do so via a call to ModBibiloMarc.
 324
 325 The goal of this API is to have a similar effect to using AddBiblio
 326 and AddItems in succession, but without inefficient repeated
 327 parsing of the MARC XML bib record.
 328
 329 This function returns an arrayref of new itemsnumbers and an arrayref of item
 330 errors encountered during the processing.  Each entry in the errors
 331 list is a hashref containing the following keys:
 332
 333 =over
 334
 335 =item item_sequence
 336
 337 Sequence number of original item tag in the MARC record.
 338
 339 =item item_barcode
 340
 341 Item barcode, provide to assist in the construction of
 342 useful error messages.
 343
 344 =item error_code
 345
 346 Code representing the error condition.  Can be 'duplicate_barcode',
 347 'invalid_homebranch', or 'invalid_holdingbranch'.
 348
 349 =item error_information
 350
 351 Additional information appropriate to the error condition.

 422
 423 This function updates an item record based on a supplied
 424 C<MARC::Record> object containing an embedded item field.
 425 This API is meant for the use of C<additem.pl>; for
 426 other purposes, C<ModItem> should be used.
 427
 428 This function uses the hash %default_values_for_mod_from_marc,
 429 which contains default values for item fields to
 430 apply when modifying an item.  This is needed beccause
 431 if an item field's value is cleared, TransformMarcToKoha
 432 does not include the column in the
 433 hash that's passed to ModItem, which without
 434 use of this hash makes it impossible to clear
 435 an item field's value.  See bug 2466.
 436
 437 Note that only columns that can be directly
 438 changed from the cataloging and serials
 439 item editors are included in this hash.

 500
 501 Change one or more columns in an item record and update
 502 the MARC representation of the item.
 503
 504 The first argument is a hashref mapping from item column
 505 names to the new values.  The second and third arguments
 506 are the biblionumber and itemnumber, respectively.
 507
 508 The fourth, optional parameter, C<$unlinked_item_subfields>, contains
 509 an arrayref containing subfields present in the original MARC
 510 representation of the item (e.g., from the item editor) that are
 511 not mapped to C<items> columns directly but should instead
 512 be stored in C<items.more_subfields_xml> and included in
 513 the biblio items tag for display and indexing.
 514
 515 If one of the changed columns is used to calculate
 516 the derived value of a column such as C<items.cn_sort>,
 517 this routine will perform the necessary calculation
 518 and set the value.

1007
1008 The sub returns a reference to a list of hashes, each containing
1009 itemnumber, author, title, barcode, item callnumber, and date last
1010 seen. It is ordered by callnumber then title.
1011
1012 The required minlocation & maxlocation parameters are used to specify a range of item callnumbers
1013 the datelastseen can be used to specify that you want to see items not seen since a past date only.
1014 offset & size can be used to retrieve only a part of the whole listing (defaut behaviour)
1015 $statushash requires a hashref that has the authorized values fieldname (intems.notforloan, etc...) as keys, and an arrayref of statuscodes we are searching for as values.
1016
1017 $iTotalRecords is the number of rows that would have been returned without the $offset, $size limit clause

1888
1889 This hash keeps track of item columns that
1890 are strictly derived from other columns in
1891 the item record and are not meant to be set
1892 independently.
1893
1894 Each key in the hash should be the name of a
1895 column (as named by TransformMarcToKoha).  Each
1896 value should be hashref whose keys are the
1897 columns on which the derived column depends.  The
1898 hashref should also contain a 'BUILDER' key
1899 that is a reference to a sub that calculates
1900 the derived value.

1941 calculate any derived columns.  Currently the only
1942 such column is C<items.cn_sort>.
1943
1944 This routine differs from C<_set_derived_columns_for_add>
1945 in that it needs to handle partial item records.  In other
1946 words, the caller of C<ModItem> may have supplied only one
1947 or two columns to be changed, so this function needs to
1948 determine whether any of the columns to be changed affect
1949 any of the derived columns.  Also, if a derived column
1950 depends on more than one column, but the caller is not
1951 changing all of then, this routine retrieves the unchanged
1952 values from the database in order to ensure a correct
1953 calculation.

2593
2594 Find the given $subfield in the given $tag in the given
2595 MARC::Record $record.  If the subfield is found, returns
2596 the (indicators, value) pair; otherwise, (undef, undef) is
2597 returned.
2598
2599 PROPOSITION :
2600 Such a function is used in addbiblio AND additem and serial-edit and maybe could be used in Authorities.
2601 I suggest we export it from this module.
