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: =over 4 =item 1. in the biblio,biblioitems,items, etc tables, which are limited to a one-to-one mapping to underlying MARC data =item 2. as raw MARC in the Zebra index and storage engine =item 3. as raw MARC the biblioitems.marc and biblioitems.marcxml =back In the 3.0 version of Koha, the authoritative record-level information is in biblioitems.marcxml 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. =over 4 =item 1. Compared with MySQL, Zebra is slow to update an index for small data changes -- especially for proc-intensive operations like circulation =item 2. Zebra's index has been known to crash and a backup of the data is necessary to rebuild it in such cases =back 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: =over 4 =item 1. Add*/Mod*/Del*/ - high-level external functions suitable for being called from external scripts to manage the collection =item 2. _koha_* - low-level internal functions for managing the koha tables =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. =item 4. Zebra functions used to update the Zebra index =item 5. internal helper functions such as char_decode, checkitems, etc. Some of these probably belong in Koha.pm =back 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 : =over 4 =item 1. save datas in biblio and biblioitems table, that gives us a biblionumber and a biblioitemnumber =item 2. add the biblionumber and biblioitemnumber into the MARC records =item 3. save the marc record =back When dealing with items, we must : =over 4 =item 1. save the item in items table, that gives us an itemnumber =item 2. add the itemnumber to the item MARC field =item 3. overwrite the MARC record (with the added item) into biblioitems.marc(xml) When modifying a biblio or an item, the behaviour is quite similar. =back =head1 EXPORTED FUNCTIONS =head2 AddBiblio =over 4 ($biblionumber,$biblioitemnumber) = AddBiblio($record,$frameworkcode); =back Exported function (core API) for adding a new biblio to koha. The first argument is a C object containing the bib to add, while the second argument is the desired MARC framework code. This function also accepts a third, optional argument: a hashref to additional options. The only defined option is C, which if present and mapped to a true value, causes C to omit the call to save the MARC in C and C This option is provided B for the use of scripts such as C that may need to do some manipulation of the MARC record for item parsing before saving it and which cannot afford the performance hit of saving the MARC record twice. Consequently, do not use that option unless you can guarantee that C will be called. =cut sub AddBiblio { my $record = shift; my $frameworkcode = shift; my $options = @_ ? shift : undef; my $defer_marc_save = 0; if (defined $options and exists $options->{'defer_marc_save'} and $options->{'defer_marc_save'}) { $defer_marc_save = 1; } my ($biblionumber,$biblioitemnumber,$error); my $dbh = C4::Context->dbh; # transform the data into koha-table style data my $olddata = TransformMarcToKoha( $dbh, $record, $frameworkcode ); ($biblionumber,$error) = _koha_add_biblio( $dbh, $olddata, $frameworkcode ); $olddata->{'biblionumber'} = $biblionumber; ($biblioitemnumber,$error) = _koha_add_biblioitem( $dbh, $olddata ); _koha_marc_update_bib_ids($record, $frameworkcode, $biblionumber, $biblioitemnumber); # update MARC subfield that stores biblioitems.cn_sort _koha_marc_update_biblioitem_cn_sort($record, $olddata, $frameworkcode); # now add the record $biblionumber = ModBiblioMarc( $record, $biblionumber, $frameworkcode ) unless $defer_marc_save; &logaction(C4::Context->userenv->{'number'},"CATALOGUING","ADD",$biblionumber,"biblio") if C4::Context->preference("CataloguingLog"); return ( $biblionumber, $biblioitemnumber ); } =head2 ModBiblio ModBiblio( $record,$biblionumber,$frameworkcode); Exported function (core API) to modify a biblio =cut sub ModBiblio { my ( $record, $biblionumber, $frameworkcode ) = @_; if (C4::Context->preference("CataloguingLog")) { my $newrecord = GetMarcBiblio($biblionumber); &logaction(C4::Context->userenv->{'number'},"CATALOGUING","MODIFY",$biblionumber,"BEFORE=>".$newrecord->as_formatted); } my $dbh = C4::Context->dbh; $frameworkcode = "" unless $frameworkcode; # get the items before and append them to the biblio before updating the record, atm we just have the biblio my ( $itemtag, $itemsubfield ) = GetMarcFromKohaField("items.itemnumber",$frameworkcode); my $oldRecord = GetMarcBiblio( $biblionumber ); # parse each item, and, for an unknown reason, re-encode each subfield # if you don't do that, the record will have encoding mixed # and the biblio will be re-encoded. # strange, I (Paul P.) searched more than 1 day to understand what happends # but could only solve the problem this way... my @fields = $oldRecord->field( $itemtag ); foreach my $fielditem ( @fields ){ my $field; foreach ($fielditem->subfields()) { if ($field) { $field->add_subfields(Encode::encode('utf-8',$_->[0]) => Encode::encode('utf-8',$_->[1])); } else { $field = MARC::Field->new("$itemtag",'','',Encode::encode('utf-8',$_->[0]) => Encode::encode('utf-8',$_->[1])); } } $record->append_fields($field); } # update biblionumber and biblioitemnumber in MARC # FIXME - this is assuming a 1 to 1 relationship between # biblios and biblioitems my $sth = $dbh->prepare("select biblioitemnumber from biblioitems where biblionumber=?"); $sth->execute($biblionumber); my ($biblioitemnumber) = $sth->fetchrow; $sth->finish(); _koha_marc_update_bib_ids($record, $frameworkcode, $biblionumber, $biblioitemnumber); # load the koha-table data object my $oldbiblio = TransformMarcToKoha( $dbh, $record, $frameworkcode ); # update MARC subfield that stores biblioitems.cn_sort _koha_marc_update_biblioitem_cn_sort($record, $oldbiblio, $frameworkcode); # update the MARC record (that now contains biblio and items) with the new record data &ModBiblioMarc( $record, $biblionumber, $frameworkcode ); # modify the other koha tables _koha_modify_biblio( $dbh, $oldbiblio, $frameworkcode ); _koha_modify_biblioitem_nonmarc( $dbh, $oldbiblio ); return 1; } =head2 ModBiblioframework ModBiblioframework($biblionumber,$frameworkcode); Exported function to modify a biblio framework =cut sub ModBiblioframework { my ( $biblionumber, $frameworkcode ) = @_; my $dbh = C4::Context->dbh; my $sth = $dbh->prepare( "UPDATE biblio SET frameworkcode=?
