Unfortunately, I don’t have time to really elaborate today, but perhaps I will come back and explain later. Until then, here is a list of links…

A bit of talk about how Koha and Zebra link together using CCL/PQF

CCL Special Attribute Combos
http://www.indexdata.com/yaz/doc/tools.html#ccl.special.attribute.combos
In terms of adjusting Zebra/Koha settings, you’ll want to look at:
bib1.att
ccl.properties
record.abs
Bib1.att lists and maps bib-1 attributes (default from the library of congress spec and special added ones for Koha)
Ccl.properties maps CCL to BIB1/PQF
Record.abs maps MARC fields to BIB1
Also, since it’s really hard to find information about how to construct PQF queries using BIB1…
There are 6 types of Bib-1 attributes. Each type has a variety of codes within that type. To create a query, you would type something like the following into Yaz or whatever else you’re using that utilizes PQF:
f @attr 1=4 computer
f stands for find in yaz
@attr stands for attribute (you need to write one of these for each attribute you’re creating)
1=4 stands for type 1: use attributes with a code of 4 for title
1=4 -> use attribute=title
It’s actually quite straightforward, but it’s quite rare to find it spelled out for you on the Web!
