Yes, I'm quite sure Norwegian libraries and librarians will find a
requirement to convert their beloved NORMARC-records into MARC21 before
migrating to Koha quite a turn-off. I guess it will also be problematic to
import records via Z39.50 from our national library or other large libraries
into a MARC21 system. 

The size of the task - and the different sub-tasks involved - is one of the
things I'm trying to figure out! ;-)

Yep, Zebra is trotting along at a nice pace. 

Just to break the tasks down here:

That would mean providing the information found in
/etc/zebradb/marc_defs/marc21/
http://git.koha.org/cgi-bin/gitweb.cgi?p=Koha;a=tree;f=etc/zebradb/marc_defs/
marc21
but for NORMARC, right?

That would be done through the ISBD pref?

Where should this be done?

With something like "rebuild_zebra.pl -b -a -z", right? 

What strikes me as somewhat strange about the behaviour I'm seeing now, is
that reindexing does not seem to affect it. If I load my definition I get the
error, without me doing any reindexing. To me it looks like Koha is doing
some checking of the MARC-structure and throwing an error before it performs
an actual search?
