package C4::Biblio; 

# Contains all sub used for biblio management. tables :
# biblio, biblioitems, items
# bibliosubject, bibliosubtitle

# 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 APIs :
# 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.
#
# 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 ;-)
