[Koha-devel] popularity (in 3.0) [for joshua]

[Paul POULAIN]

Hello all, (and mainly joshua)

The popularity, in dev_week, is stored in items (952). That is wrong 
according to me, because, if a book we have 4 items is issued 
20+19+31+38=98 times, it's much more popular than a book issued 45+0+0+0 
times

That's why I propose to move the popularity field to a biblio area.
The popularity field is indexed in zebra through update_items.pl script.

I suggest using a non standard MARC field for this.

For UNIMARC, I think 2xx area (descriptive informations) could be a good 
candidate. I choose (randomly) 349$a to store it. It will contain 
summ(items.issues) where biblionumber=xx

I modify update_items & zebra config files accordingly, let me know if 
you are OK with this suggestion + let me know what to use in MARC21.
