Hi,
I'm very new to Koha, so please excuse me if the following is obvious. I
wasn't for me, and in case is isn't for others too, I'd like to share
the information. That way it'll be in the mailing list archives for
others to find.
I've setup a Koha 22.11 instance for my wife, who's a librarian. I'm
not.
We're in Italy, so the instance uses UNIMARC, which allows for smooth
interaction with the SBN, the Italian National Library System.
A lot of our records are imported from the SBN, but not all. Some will
have to come from LOC, British Library and others.
If I searched LOC or BL (both of which use MARC21) for a record, there
would be some results, but the titles, authors and ISBNs wouldn't appear
in the search result. The only column visible was the Z39.50 server
name. There were not error messages, just no data displayed.
A click on a row, then selecting "Preview MARC" on the menu would show
the record, but not in UNIMARC format.
In my ignorance I expected Koha to do the conversion, after all there's
a choice of format in the Z39.50 server configuration, but apparently it
doesn't.
Getting my head around this took a while, but in the end I found out
that an XSLT conversion is needed, even though the displayed MARC
records don't look like XML at all.
There's an old bug report here:
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=6536
which discusses the problem. It is marked FIXED and CLOSED.
In there I found a tentative MARC21 to UNIMARC XSLT file which didn't
work. My Koha instance gave me a "500 Internal server error".
Searching a bit more, I found this by the author or MarcEdit:
https://github.com/reeset/unimarc
where there's another MARC21 to UNIMARC XSLT file that actually works:
https://raw.githubusercontent.com/reeset/unimarc/master/marc21xml2unimarc.xsl
The solution to my Z39.50 import from MARC21 servers into an UNIMARC
Koha instance was to download the file from the link above, dump it
unmodified in /etc/koha/sites/instance/marc21xml2unimarc.xsl and then
put that path into the configuration of each individual Z39.50 server
that uses MARC21.
So at this point it works, we're happy, but I did expect Koha to take
care of this. If not, why does it ask us to specify which MARC flavour
the server uses, only not to act on the information?
