[Koha] Adding Z39.50 servers

[library at ssst.edu.ba]

Hello René, 

Thank you again for taking the time to explain - I had to work out how to accomplish some things in Linux terminal since until this year I had no experience with it and it took me quite some time to understand how some things worked. 

To cut the long story short, I got the marc21xml2unimarc.xsl file to download to the server set aside for me by out IT manager, and then added the full path to the Z39.50 settings for LOC. I'm waiting for the password for BL so I can test it for that source. 

Before I actually do any imports, I will have to go through my framework and edit out the tags I won't need, but that's a topic for another post. 

Best regards

Aida Đikić

Hi Aida Đikić

It can be done.

I have an old blog where I keep notes and things, and I wrote it down:

Here's the relevant section, but the links didn't come over with copy-paste.



MARC flavours

There are several flavours of MARC records. The major ones are MARK21 
(or USMARC) and UNIMARC, but in Europe most countries seem to use some 
locally modified format of one or the other.

We’re in Italy, so I configured our Koha instance to use UNIMARC.

The problem with LoC and BL is, I discoved after a while, one of 
different MARC flavours. Our instance uses UNIMARC while LoC and BL use 
MARC21.

Koha doesn’t convert from one format to the other when you import a 
record. Koha does ask you when you configure a Z39.50 server, which 
format the server uses, but it still doesn’t convert the data.

This took me a while.

MARC records are not XML, but in the X39.50 server configuration there 
was a fields for custom XSLT files. Maybe Koha worked internally with 
MARCXML which is an XML representation of a MARC record?

Apparently lots of libraries use a program called MarcEdit to do this 
conversion between MARC flavours. It is written by a Terry Reese, and lo 
and behold if he didn’t have such “MARC21 to UNIMARC” XSLT files on 
Github.

I downloaded his marc21xml2unimarc.xsl file, copied it to my VPS, 
entered the pathname in the Z39.50 server configuration, and suddenly my 
imports from LoC and BL worked perfectly.
