Hi Mohamad,
I am not sure how much performance for both methods would differ. Just be aware that you will have to maintain your changes through updates and changes in Koha's architecture, so that is something you need to assess and decide if it's worth doing for the kind of change you want to make. Alternatively you can also think about contributing changes back to the community, of course :) For the fields you mentioned I am not sure if they would make a good general feature - I'd expect them in the serials module and not on item level.

Thanks Katrin. using my method I were able to see fields in KOHA after editting kohastructure.sql to reflect my changes there and running update_dbix_class_files.pl from koha root dir. and finally assign mapping. I test you suggested method and work correctly, but whats about performance? I think to be in a separate column much better for performance, cause in your case every time need to access these new fields need more XML parsing .

But there is another way of adding more information/custom fields to the items table: In items there is the column more_subfields_xml. This is used to store additional content. All you need to do is change your MARC framework and add additional 952 subfields without any mapping. Without a mapping to a database column, the content will be automatically saved in more_subfields_xml as XML that you can query with SQL, add to the item search by configuration etc. So no changes to Koha's code and db structure would be needed and you won't have any problems with updates. Hope this helps, Katrin On 04.03.19 14:36, Mohamad F.
