1st draft for MARC biblio deletion.
Still does not work well, but at least, Biblio.pm compiles & it should'nt break too many things
(Note the trash in the MARCdetail, but don't use it, please :-) )
I changed this behaviour :
if notforloan is set for a given item, and NOT for all items from this itemtype, the notforloan is kept.
If notforloan is set for itemtype, it's used (and impossible to loan a specific item from this itemtype)
This supports is only for MARC <-> OLD-DB link. It worked previously, but values entered as MARC were not reported to OLD-DB, neither values entered as OLD-DB were reported to MARC.
Note that some OLD-DB subs are strange (dummy ?) see OLDmodsubject, OLDmodsubtitle, OLDmodaddiauthor in C4/Biblio.pm
For example it seems impossible to have more that 1 addi author and 1 subtitle. In MARC it's not the case. So, if you enter more than one, I'm afraid only the LAST will be stored.
z3950 search and import seems to works fine.
Let me explain how :
* a "search z3950" button is added in the addbiblio template.
* when clicked, a popup appears and z3950/search.pl is called
* z3950/search.pl calls addz3950search in the DB
* the z3950 daemon retrieve the records and stores them in z3950results AND in marc_breeding table.
* as long as there as searches pending, the popup auto refresh every 2 seconds, and says how many searches are pending.
* when the user clicks on a z3950 result => the parent popup is called with the requested biblio, and auto-filled
Note :
* character encoding support : (It's a nightmare...) In the z3950servers table, a "encoding" column has been added. You can put "UNIMARC" or "USMARC" in this column. Depending on this, the char_decode in C4::Biblio.pm replaces marc-char-encode by an iso 8859-1 encoding. Note that in the breeding import this value has been added too, for a better support.
* the marc_breeding and z3950* tables have been modified : they have an encoding column and the random z3950 number is stored too for convenience => it's the key I use to list only requested biblios in the popup.
It was due to an illegal contruction in Koha : we tried to retrive subfields from <10 tags.
That's not possible. MARC::Record accepted this in 0.93 version, but it was fixed after.
Now, the construct/retrieving is OK !
* worked in 1.9.0, but not in 1.9.1 :
- modif of a biblio didn't work
- empty fields where not shown when modifying a biblio. empty fields managed by the library (ie in tab 0->9 in MARC parameter table) MUST be entered, even if not presented.
* did not work before :
- repeatable subfields now works correctly. Enter 2 subfields separated by | and they will be splitted during saving.
- dropped the last subfield of the MARC form :-(
Internal changes :
- MARCmodbiblio now works by deleting and recreating the biblio. It's not perf optimized, but MARC is a "do_something_impossible_to_trace" standard, so, it's the best solution. not a problem for me, as biblio are rarely modified.
Note the MARCdelbiblio has been rewritted to enable deletion of a biblio WITHOUT deleting items.
Those fields doesn't have subfields.
In koha, we will use a specific "trick" : fields <10 will have a "virtual" subfield : "@".
Note it's only virtual : when rebuilding the MARC::Record, the koha API handle correctly "@" subfields => the resulting MARC record has a 00x field without subfield.

'mandatory' property to a per-subfield 'tag_mandatory' template parameter,
so that addbiblio.tmpl can distinguish between mandatory subfields in a
mandatory tag and mandatory subfields in an optional tag
Not-minor factoring in acqui.simple/addbiblio.pl to make the if-else blocks
smaller, and to add some POD; need further testing for this
Added function to check if a MARC subfield name is "koha-internal" (instead
of checking it for 'lib' and 'tag' everywhere); temporarily added to Koha.pm
Use above function in acqui.simple/additem.pl and search.marc/search.pl
* many bugfixes
* adding value_builder : you can map a subfield in the marc_subfield_structure to a sub stored in "value_builder" directory. In this directory you can create screen used to build values with any method. In this commit is a 1st draft of the builder for 100$a unimarc french subfield, which is composed of 35 digits, with 12 differents values (only the 4th first are provided for instance)
* 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.
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.
Not related to MARC :
* removed HLT- empty link when no basket for a supplier (should be useful to copy this into rel-1-2 i think)
* fixed some "use of uninitialized value"
related to MARC
* changed use Acquisition to use Catalogue, new package for MARC management
For instance, nothing is done to MARC DB, but structure is modified (see Biblio.pm for details), and everything seems to work : it's still possible to use acqui, and it fills old-DB pretty good.
WARNING : if you work on main trunk, please note Acquisition.pm is NO MORE USED in /acqui/ system. Every sub in Acquisition.pm has been moved to Biblio.pm or Catalogue.pm.
0- Requires MARC::Record from cpan to work
1- divided Catalogue.pm in 2 parts :
Biblio.pm ,that contains biblio management
Catalogue.pm, that contains acquisition management.
When ended, they will replace the Acquisition.pm package
2- Created MARCxxx functions :
* MARCgetbiblio : retrieves a MARC::Record from the bibid passed in parameter (working, see test.pl script)
* MARCaddbiblio : creates a MARC-DB entry, for a MARC::Record given as parameter. (working)
* MARCmodsubfield : modifies a subfield for a given subfieldid
* MARCfingsubfield : retrieves a subfieldvalue from a bibid/tag/subfield
* MARCaddsubfield : adds a subfield to biblio into the DB
* MARCkoha2marc : builds a MARC::Record, given a biblionumber, a biblioitemnumber and/or an itemnumber. (working).
TODO :
A lot ;-))))
For instance, you can create only a MARC-DB entry from a old-DB entry. Note some questions are still to solve around bibid (old-DB/MARC-DB)...
