[Koha-devel] Differences beetween indexes on holding data

[Zeno Tajoli]

Hi to all,

reading the indexes defintions,
etc/zebradb/marc_defs/marc21/biblios/record.abs
etc/zebradb/marc_defs/unimarc/biblios/record.abs

I have understand that Unimarc and MARC21 have different indexes on holding
data. But in fact Koha templates are only one, so we probably use the 
same indexes
with different source.
The situation [reading files from maintenance tree]:

In common
IndexName		Unimarc	MARC21
barcode		995$f		952$p
holdingbranch	995$c,995$d 		952$b
homebranch	995$a, 995$b 		952$a
Local-classification	995$k 		952$o
Local-Number 		090$9 		999$c
location 		995$e 		952$c
lost 			995$2		952$1
Note			995$u 		952$z
onloan			995$n		952$q

Only Unimarc
item 			995
date-entered-on-file 	099$c
Date/time-last-modified 099$d
Host-item 		995$a, 995$b
LC-card-number 	995$j
Call-Number 		995$k
lcn 			995$k
popularity 		995$s

Only MARC21
totalissues 		942$0
cn-bib-source 		942$2
cn-bib-sort 		942$6
itemtype 		942$c
cn-class 		942$h
cn-item 		942$i
cn-prefix 		942$k
cn-suffix 		942$m
Suppress 		942$n
withdrawn 		952$0
classification-source 	952$2
materials-specified 	952$3
damaged 		952$4
restricted 		952$5
cn-sort 		952$6
notforloan 		952$7
ccode 		952$8
itemnumber 		952$9
Date-of-acquisition 	952$d
acqsource 		952$e
coded-location-qualifier 952$f
price 			952$g
stack 			952$j
issues 		952$l
renewals 		952$m
reserves 		952$n
datelastseen 		952$r
datelastborrowed 	952$s
copynumber 		952$t
uri 			952$u
replacementprice 	952$v
replacementpricedate 	952$w
itype 			952$y
biblioitemnumber 	999$d

Question:
Why so many indexes only for one type of MARC (Unimarc or MARC21)?
Do we need to coordinate more indexes ?
There is a simple way to know which indexes on local / holdings are 
used in the koha template ?


Bye to all
