[Koha-devel] Default Koha to MARC Mappings on nonexistent table fields?

Hey All, We have set up a plain Koha 3 install which we are using for import testing. I wrote a script to rebuild the biblio, biblioitems, and items tables from biblioitems.marcxml using the data stored in marc_subfield_structure. What I have found is that some of the framework code seems to reference table columns that do not exists. The columns referenced are: * bibliosubject.subject ( there is no bibliosubject table ) * biblioitems.cn_edition * biblioitems.cn_prefix Can anyone provide any insight to this situation? Are these dead columns, or columns that were never added, or just bugs? Thanks, Kyle http://www.kylehall.info Information Technology Crawford County Federated Library System ( http://www.ccfls.org )
