# road to 1.3.1 : viewing MARC biblio
#
# Revision 1.15  2002/10/05 09:49:25  arensb
# Merged with arensb-context branch: use C4::Context->dbh instead of
# &C4Connect, and generally prefer C4::Context over C4::Database.

# Revision 1.14  2002/10/03 11:28:18  tipaul
# Extending Context.pm to add stopword management and using it in MARC-API.
# First benchmarks show a medium speed improvement, which  is nice as this part is heavily called.

#
# Revision 1.8  2002/09/10 13:53:52  tipaul
# MARC API continued...
# * some bugfixes
# * multiple item management : MARCadditem and MARCmoditem have been added. They suppose that ALL the MARC field linked to koha-item are in the same MARC tag (on the same line of MARC file)
#
# Note : it should not be hard for marcimport and marcexport to re-link fields from internal tag/subfield to "legal" tag/subfield.

# pod documenting the API.
#
# Revision 1.5  2002/07/24 16:11:37  tipaul
# Now, the API...
# Database.pm and Output.pm are almost not modified (var test...)
#
# Biblio.pm is almost completly rewritten.
#
# WHAT DOES IT ??? ==> END of Hitchcock suspens
#
# 1st, it does... nothing...
# Every old API should be there. So if MARC-stuff is not done, the behaviour is EXACTLY the same (if there is no added bug, of course). So, if you use normal acquisition, you won't find anything new neither on screen or old-DB tables ...
#
# All old-API functions have been cloned. for example, the "newbiblio" sub, now has become :
# * a "newbiblio" sub, with the same parameters. It just call a sub named OLDnewbiblio
# * a "OLDnewbiblio" sub, which is a copy/paste of the previous newbiblio sub. Then, when you want to add the MARC-DB stuff, you can modify the newbiblio sub without modifying the OLDnewbiblio one. If we correct a bug in 1.2 in newbiblio, we can do the same in main branch by correcting OLDnewbiblio.
# * The MARC stuff is usually done through a sub named MARCxxx where xxx is the same as OLDxxx. For example, newbiblio calls MARCnewbiblio. the MARCxxx subs use a MARC::Record as parameter.
# The last thing to solve was to manage biblios through real MARC import : they must populate the old-db, but must populate the MARC-DB too, without loosing information (if we go from MARC::Record to old-data then back to MARC::Record, we loose A LOT OF ROWS). To do this, there are subs beginning by "ALLxxx" : they manage datas with MARC::Record datas. they call OLDxxx sub too (to populate old-DB), but MARCxxx subs too, with a complete MARC::Record ;-)
#
# In Biblio.pm, there are some subs that permits to build a old-style record from a MARC::Record, and the opposite. There is also a sub finding a MARC-bibid from a old-biblionumber and the opposite too.
# Note we have decided with steve that a old-biblio <=> a MARC-Biblio.
#


# move from 1.2 to 1.4 version : 
# 1.2 and previous version uses a specific API to manage biblios. This API uses old-DB style parameters.
# In the 1.4 version, we want to do 2 differents things :
#  - keep populating the old-DB, that has a LOT less datas than MARC
#  - populate the MARC-DB
# To populate the DBs we have 2 differents sources :
#  - the standard acquisition system (through book sellers), that does'nt use MARC data
#  - the MARC acquisition system, that uses MARC data.
#
# thus, we have 2 differents cases :
#   - with the standard acquisition system, we have non MARC data and want to populate old-DB and MARC-DB, knowing it's an incomplete MARC-record
#   - with the MARC acquisition system, we have MARC datas, and want to loose nothing in MARC-DB. So, we can't store datas in old-DB, then copy in MARC-DB.
#       we MUST have an API for true MARC data, that populate MARC-DB then old-DB
#
# That's why we need 4 subs :
# all subs beginning by MARC manage only MARC tables. They manage MARC-DB with MARC::Record parameters
# all subs beginning by OLD manage only OLD-DB tables. They manage old-DB with old-DB parameters
# all subs beginning by ALL manage both OLD-DB and MARC tables. They use MARC::Record as parameters. it's the API that MUST be used in MARC acquisition system
# all subs beginning by seomething else are the old-style API. They use old-DB as parameter, then call internally the OLD and MARC subs.
#
# only ALL and old-style API should be used in koha. MARC and OLD is used internally only
#
# Thus, we assume a nice translation to future versions : if we want in a 1.6 release completly forget old-DB, we can do it easily.
# in 1.4 version, the translations will be nicer, as we have NOTHING to do in code. Everything has to be done in Biblio.pm ;-)

# all the following subs takes a MARC::Record as parameter and manage
# the MARC-DB. They are called by the 1.0/1.2 xxx subs, and by the
# ALLxxx subs (xxx deals with old-DB parameters, the ALLxxx deals with MARC-DB parameter)

=head1 SYNOPSIS

  MARCxxx related subs
  all subs requires/use $dbh as 1st parameter.
  NOTE : all those subs are private and must be used only inside Biblio.pm (called by a old API sub, or the ALLsub)

=head1 DESCRIPTION

=head2 @tagslib = &MARCgettagslib($dbh,1|0);
      last param is 1 for liblibrarian and 0 for libopac
      returns a hash with tag/subfield meaning

=head2 ($tagfield,$tagsubfield) = &MARCfindmarc_from_kohafield($dbh,$kohafield);
      finds MARC tag and subfield for a given kohafield
      kohafield is "table.field" where table= biblio|biblioitems|items, and field a field of the previous table

=head2 $biblionumber = &MARCfind_oldbiblionumber_from_MARCbibid($dbh,$MARCbibi);
      finds a old-db biblio number for a given MARCbibid number

=head2 $bibid = &MARCfind_MARCbibid_from_oldbiblionumber($dbh,$oldbiblionumber);
      finds a MARC bibid from a old-db biblionumber

=head2 &MARCaddbiblio($dbh,$MARC::Record,$biblionumber);
      creates a biblio (in the MARC tables only). $biblionumber is the old-db biblionumber of the biblio

=head2 &MARCaddsubfield($dbh,$bibid,$tagid,$indicator,$tagorder,$subfieldcode,$subfieldorder,$subfieldvalue);
      adds a subfield in a biblio (in the MARC tables only).
     
=head2 $MARCRecord = &MARCgetbiblio($dbh,$bibid);
      Returns a MARC::Record for the biblio $bibid.

=head2 &MARCmodbiblio($dbh,$bibid,$delete,$record);
      MARCmodbiblio changes a biblio for a biblio,MARC::Record passed as parameter
      if $delete == 1, every field/subfield not found is deleted in the biblio
      otherwise, only data passed to MARCmodbiblio is managed.
      thus, you can change only a small part of a biblio (like an item, or a subtitle, or a additionalauthor...)

=head2 ($subfieldid,$subfieldvalue) = &MARCmodsubfield($dbh,$subfieldid,$subfieldvalue);
      MARCmodsubfield changes the value of a given subfield

=head2 $subfieldid = &MARCfindsubfield($dbh,$bibid,$tag,$subfieldcode,$subfieldorder,$subfieldvalue);
      MARCfindsubfield returns a subfield number given a bibid/tag/subfieldvalue values.
      Returns -1 if more than 1 answer

=head2 $subfieldid = &MARCfindsubfieldid($dbh,$bibid,$tag,$tagorder,$subfield,$subfieldorder);
      MARCfindsubfieldid find a subfieldid for a bibid/tag/tagorder/subfield/subfieldorder

=head2 &MARCdelsubfield($dbh,$bibid,$tag,$tagorder,$subfield,$subfieldorder);
      MARCdelsubfield delete a subfield for a bibid/tag/tagorder/subfield/subfieldorder

=head2 &MARCdelbiblio($dbh,$bibid);
      MARCdelbiblio delete biblio $bibid

=head2 $MARCRecord = &MARCkoha2marcBiblio($dbh,$biblionumber,biblioitemnumber);
      MARCkoha2marcBiblio is a wrapper between old-DB and MARC-DB. It returns a MARC::Record builded with old-DB biblio/biblioitem

=head2 $MARCRecord = &MARCkoha2marcItem($dbh,$biblionumber,itemnumber);
      MARCkoha2marcItem is a wrapper between old-DB and MARC-DB. It returns a MARC::Record builded with old-DB item

=head2 $MARCRecord = &MARCkoha2marcSubtitle($dbh,$biblionumber,$subtitle);
      MARCkoha2marcSubtitle is a wrapper between old-DB and MARC-DB. It returns a MARC::Record builded with old-DB subtitle

=head2 &MARCkoha2marcOnefield => used by MARCkoha2marc and should not be useful elsewhere

=head2 $olddb = &MARCmarc2koha($dbh,$MARCRecord);
      builds a hash with old-db datas from a MARC::Record

=head2 &MARCmarc2kohaOnefield => used by MARCmarc2koha and should not be useful elsewhere

=head2 MARCaddword => used to manage MARC_word table and should not be useful elsewhere

=head2 MARCdelword => used to manage MARC_word table and should not be useful elsewhere

=head1 SYNOPSIS
  OLDxxx related subs
  all subs requires/use $dbh as 1st parameter.
  those subs are used by the MARC-compliant version of koha : marc import, or marc management.

  They all are the exact copy of 1.0/1.2 version of the sub
  without the OLD. The OLDxxx is called by the original xxx sub.
  the 1.4 xxx sub also builds MARC::Record an calls the MARCxxx
 
  WARNING : there is 1 difference between initialxxx and OLDxxx :
  the db header $dbh is always passed as parameter
  to avoid over-DB connexion
