[Koha-devel] suspected error in record.abs and proposal for a new index

[Mathieu Saby]

Hi
I'd like to edit Unimarc Record.abs to create an index for dissertation 
note (field 328 : http://www.bnf.fr/documents/B328_6_2010.pdf)

I remark this field in Marc21 is field 502 :
http://www.loc.gov/marc/bibliographic/bd502.html : 502 - Dissertation 
Note (R)

But in Marc21 Record.abs, this field is mapped with index "Material-type"
line 155 :
melm 502        Material-type

An other field is also mapped with Material-type in Marc21 : 007
line  53
melm 007        
Microform-generation:n:range(data,11,1),Material-type,ff7-00:w:range(data,0,1),ff7-01:w:range(data,1,1),ff7-02:w:range(data,2,1),ff7-01-02:w:range(data,0,2)

I've never used Marc21, but it sounds a bit strange for me.
Could Marc21 guys tell me if this 502 mapping with "Material-type" index 
is a bug?
If it is a bug, what about creating a new index, "dissertation-note" for 
example, mapped with 502 in Marc21 and 328 in Unimarc ?

In bib1.att, there is Dissertation-information  = 1056  which could I 
suppose be user for that purpose.
