# adding Opac Browser feature : the build_browser_and_cloud.pl script will :
# - fill the browser table, that enable browsing, digit by digit of a given category, the catalogue. A complete dewey classification is provided in the script, active only for french libraries, of course (although, for instance, the script check that the catalogue is in english for developping convenience)
# - fill the tags table, that contains the subject cloud.
#
# The cloud part is a copy of the previous build_tags.pl script that can be deleted : those 2 scripts require to parse all the catalogue to extract interesting data, so they are long. It's useless to parse the catalogue twice !
#
# The commit also add the systempreference to hide/show the OpacBrowse in database & in systempref management script.
#
# IMPROVEMENTS to do :
# - the script that builds the tables can be improved to update only last week biblios (at the price of a small error in value links, but it's not a problem).
# - add, in parameters section, a place to edit browser descriptions. The build script has to be updated to to avoid deleting existing browser descriptions.

# This feature had been requested for a while by my librarians. The 2 uses we can imagine are :
# - for websites => show the link directly in the result list, to avoid 1 clic (& there is no need for a size/editor/publicationyear for web sites)
# - for serial publications => show some serial specific informations.
#
# This commit should do everything that is needed for this feature.

# with this program, the librararians will can check , and specify the method of notification of documents in overdue
#
# little explanation :
#
#     - At first, the datas come from accountlines, generated by accounlines (type 'FU')
#     - There is three levels of notification (come from overduerules ....)
#     - there is four methods of notification :
#         - letter (for us, use an openoffice program ....)
#         - Mail (use a batch program)
#         - Phone (simple Method, if this method is selected, we consider that the borrower as been notified)
#         - Considered Lost (For us the third level)
#
#     - At this time we have some parameters hardcoded (Must be improve later)
#
#     - the choice of methods is hardcoded :
#         - for the first overduelevel : three methods : mail,letter,phone
#         -For the second overduelevel :only one method : letter
#         - For the Third Overdue level : only one method : Considered Lost

# * onloan & issue_date in items table. They are filled by the misc/update_items.pl script, with circulation values.

# commit for holidays and news management.
#
# Contrib from Tmer Garip (from Turkey) :
# * holiday :
# in /tools/ the holiday.pl script let you define holidays (days where the library is closed), branch by branch. You can define 3 types of holidays :
# - single day : only this day is closed
# - repet weekly (like "sunday") : the day is holiday every week
# - repet yearly (like "July, 4") : this day is closed every year.
#
# You can also put exception :
# - sunday is holiday, but "2006 March, 5th" the library will be open
#
# The holidays are used for return date calculation : the return date is set to the next date where the library is open. A systempreference (useDaysMode) set ON (Calendar) or OFF (Normal) the calendar calculation.

# Revision 1.125  2006/01/04 15:54:55  tipaul
# utf8 is a : go for beta test in HEAD.
# some explanations :
# - updater/updatedatabase => will transform all tables in innoDB (not related to utf8, just to warn you) AND collate them in utf8 / utf8_general_ci. The SQL command is : ALTER TABLE tablename DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci.
# - *-top.inc will show the pages in utf8
# - THE HARD THING : for me, mysql-client and mysql-server were set up to communicate in iso8859-1, whatever the mysql collation ! Thus, pages were improperly shown, as datas were transmitted in iso8859-1 format ! After a full day of investigation, someone on usenet pointed "set NAMES 'utf8'" to explain that I wanted utf8. I could put this in my.cnf, but if I do that, ALL databases will "speak" in utf8, that's not what we want. Thus, I added a line in Context.pm : everytime a DB handle is opened, the communication is set to utf8.
# - using marcxml field and no more the iso2709 raw marc biblioitems.marc field.
#
# Revision 1.124  2005/10/27 12:09:05  tipaul
# new features for serial module :

# - the library can create a "distribution list". this paper contains a list of borrowers (selected from the borrower list, or manually entered), and print it for a given issue. once printed, the sheet can be put on the issue and distributed to every reader on the list (one by one).

# * go to Koha >> parameters >> itemtypes >> modify (or add) an itemtype. You will see around 20 nice images to choose between (thanks to owen). If you prefer your own image, you also can type a complete url (http://www.myserver.lib/path/to/my/image.gif)
# * go to OPAC, and search something. In the result list, you now have the picture instead of the text itemtype.

# 1st commit to go to zebra.
# don't update your cvs if you want to have a working head...
#
# this commit contains :
# * updater/updatedatabase : get rid with marc_* tables, but DON'T remove them. As a lot of things uses them, it would not be a good idea for instance to drop them. If you really want to play, you can rename them to test head without them but being still able to reintroduce them...
# * Biblio.pm : modify MARCgetbiblio to find the raw marc record in biblioitems.marc field, not from marc_subfield_table, modify MARCfindframeworkcode to find frameworkcode in biblio.frameworkcode, modify some other subs to use biblio.biblionumber & get rid of bibid.
# * other files : get rid of bibid and use biblionumber instead.
#
# What is broken :
# * does not do anything on zebra yet.
# * if you rename marc_subfield_table, you can't search anymore.
# * you can view a biblio & bibliodetails, go to MARC editor, but NOT save any modif.
# * don't try to add a biblio, it would add data poorly... (don't try to delete either, it may work, but that would be a surprise ;-) )
#
# IMPORTANT NOTE : you need MARC::XML package (http://search.cpan.org/~esummers/MARC-XML-0.7/lib/MARC/File/XML.pm), that requires a recent version of MARC::Record
# Updatedatabase stores the iso2709 data in biblioitems.marc field & an xml version in biblioitems.marcxml Not sure we will keep it when releasing the stable version, but I think it's a good idea to have something readable in sql, at least for development stage.

# Letters / alert system, continuing...
#
# * adding a package Letters.pm, that manages Letters & alerts.
# * adding feature : it's now possible to define a "letter" for any subscription created. If a letter is defined, users in OPAC can put an alert on the subscription. When an issue is marked "arrived", all users in the alert will recieve a mail (as defined in the "letter"). This last part (= send the mail) is not yet developped. (Should be done this week)
# * adding feature : it's now possible to "put to an alert" in OPAC, for any serial subscription. The alert is stored in a new table, called alert. An alert can be put only if the librarian has activated them in subscription (and they activate it just by choosing a "letter" to sent to borrowers on new issues)
# * adding feature : librarian can see in borrower detail which alerts they have put, and a user can see in opac-detail which alert they have put too.
#
# Note that the system should be generic enough to manage any type of alert.
# I plan to extend it soon to virtual shelves : a borrower will be able to put an alert on a virtual shelf, to be warned when something is changed in the virtual shelf (mail being sent once a day by cron, or manually by the shelf owner. Anyway, a mail won't be sent on every change, users would be spammed by Koha ;-) )
#
# Revision 1.115  2005/08/02 16:15:34  tipaul
# adding 2 fields to letter system :
# * module (acquisition, catalogue...) : it will be usefull to show the librarian only letters he may be interested by.
# * title, that will be used as mail subject.
#
# Revision 1.114  2005/07/28 15:10:13  tipaul
# Introducing new "Letters" system : Letters will be used everytime you want to sent something to someone (through mail or paper). For example, sending a mail for overdues use letter that you can put as parameters. Sending a mail to a borrower when a suggestion is validated uses a letter too.
# the letter table contains 3 fields :
# * code => the code of the letter
# * name => the complete name of the letter
# * content => the complete text. It's a TEXT field type, so has no limits.
#
# My next goal now is to work on point 2-I "serial issue alert"
# With this feature, in serials, a user can subscribe the "issue alert". For every issue arrived/missing, a mail is sent to all subscribers of this list. The mail warns the user that the issue is arrive or missing. Will be in head.
# (see mail on koha-devel, 2005/04/07)
#
# The "serial issue alert" will be the 1st to use this letter system that probably needs some tweaking ;-)
#
# Once it will be stabilised default letters (in any languages) could be added during installer to help the library begin with this new feature.
#
# Revision 1.113  2005/07/28 08:38:41  tipaul
# For instance, the return date does not rely on the borrower expiration date. A systempref will be added in Koha, to modify return date calculation schema :
# * ReturnBeforeExpiry = yes => return date can't be after expiry date
