Thanks to Steven for clearing up the leader question. I should mention that I am willing to volunteer to build a UNIMARC version of the Z3950 Server but in order to do that I will need access to a UNIMARC Koha installation. If anyone has a test box runing UNIMARC that I can use please let me know.

Thanks,

transmitted to s.renaux, Koha project leader in Esiee School, france, that is very interested by z3950 server & is UNIMARC :-) Serge : Joshua commited z3950 server in CVS last friday : =========== Hiya, I've just committed a _basic_ Z3950 Server to CVS (in the HEAD Branch; in the z3950/server/ directory) and I wanted to make a few comments about it. (BTW: is everyone ok with moving the files in z3950 to z3950/client/ ?) First of all, the it's built using Indexdata's SimpleServer perl module Version 0.07, so if you want to use it you will have to install SimpleServer which you can get from: http://ftp.indexdata.dk/pub/simpleserver/ (BTW: whoever is doing the Koha installation script and documentation on dependencies may want to add SimpleServer). Secondly, you will need to change the leader information in Koha's MARCgetbiblio subroutine in Biblio.pm to reflect the following (or if you know how to manipulate the leader you can change it to reflect your data; this example leader should be functional for all MARC21 data). Look for the following near line 700: #---- TODO : the leader is missing $record->leader(' '); and change it to: #---- TODO : the leader is partly fixed for MARC21 $record->leader(' nac 22 1u 4500'); (BTW, Paul, you said to remind you to commit this change to CVS; I'm not sure but I wouldn't be surprised if UNIMARC's leaders were a bit different, so maybe we should hold off on that; also, I've also got some other leader qualms but they will have to wait for another email) So the actual server is implemented in a single Perl script for now (I plan to break it up for the next version) and you can get it from CVS or from my website at: http://kados.org/LibraryScience/zed-koha-server.pl (it's there for the folks who don't use CVS) You may need to change the permissions on the script--as root run: [jmf@koha]koha#chmod 755 zed-koha-server.pl Run the zed-koha-server.pl script as root: [jmf@koha]#./zed-koha-server.pl The server will take care of managing the network connections for you (it runs on port 9999), and it will spawn a new process whenever a new connection is received. The script implements a search handler and a fetch handler which allows Z3950 clients to query and retrieve records in MARC21 (the only record format it supports so far). It's set up to log to the terminal so you will need to keep the terminal running or the script will stop (I think it's the same with Koha's Z3950-Client; some day it would be nice to log to a file and run it as a service...). Let me say a word about holdings data. Right now, for historical reasons, most MARC21 installations of Koha probably use the 852 tag to store holdings data (actually I'm not sure there are any other MARC21 installations of Koha besides Nelsonville ). For example, Nelsonville Public Library uses the following: 852a Organization code 852b Home branch 852h Classification 852p Barcode However, many Z3590 clients aren't set up to pull holdings data from the 852x fields but from the 952x/942x fields. So for now I've hard-coded the server to automatically duplicate the data like this: ## Convert from 852/4 to 952: ## 942a --> 852a Organization code ## 952b --> 852b Home branch ## 942k --> 852h Classification ## 952p --> 852p Barcode So the MARC record has the data in both places. If you're fluent in Perl and you look through the documentation for SimpleServer you will see that I have implemented query-parsing using a series of very clumsy substitutions. Right now I'm working on rewriting the search_handler to use the RPN member which will allow for much cleaner parsing of the query and will make it much easier to implement new features like Boolean. But the clumsy version should work fine in most cases--Nelsonville Public Library System has been using it for about two months to interface with the statewide resource sharing program MORE with no problems. I think that's it. Let me know how it works out or if you have any questions. ==================================== Friday, January 9, 2004 18:20 CST Hi, Joshua. et al. Just a quick reply re your parenthetic point for Paul, to wit,

...

(BTW, Paul, you said to remind you to commit this change to CVS; I'm not sure but I wouldn't be surprised if UNIMARC's leaders were a bit different, so maybe we should hold off on that [snip])

my reading of the UNIMARC standards (cf. URL <http://www.ifla.org/VI/3/p1996-1/concise.htm>) indicates that the Leader and Directory have the same structure as MARC21 (and for that matter, USMARC and CANMARC). -- Paul POULAIN Consultant indépendant en logiciels libres responsable francophone de koha (SIGB libre http://www.koha-fr.org)
