[Koha] Technical help with Frameworks

[Ian Bays]

Hi Tim,

We find that the safest way of trimming frameworks to a more minimalist 
set is to "hide" the subfields.  This can be quite laborious through the 
staff interface as you have to select each subfield and look in 
"Advanced constraints" then Visibility.

If you have access at the sql level you can probably set the field 
"hidden" in table "marc_subfield_structure" to value -6 for those tags 
you do not want to appear (within your chosen framework).

You might also want to change the tab for display to all be the same (eg 
"0") if you only have 18 tags.  That just makes it clearer on the screen.

Not every field has or needs to have a koha to marc mapping, but a few 
of the koha fields must be mapped to marc subfields.  The Administration 
tool "MARC bibliographic framework test" and other tools in the same 
area should help fine tune it.

We try to avoid removing fields (tags) and subfields from frameworks as 
you could lose bibliographic data if you switch between frameworks while 
editing and save the record.  It depends what your longer-term plans 
might be for use of the system as to whether this might be a consideration.

If you stray too far from the MARC standard tags you may find that 
searching for records becomes unreliable as the search indexes are fed 
from the fields and subfields according to the MARC21 (or UNIMARC) standard.

Good luck.

We are looking to move to Koha but I find I am struggling with the initial steps of trimming down the MARC Framework.  The list of fields I have been passed by our Librarian is for only 18 or so fields.  I am therefore finding cutting down the default framework very laborious.  I have looked to Import a cut down version of the framework, from an amended export to CSV, but this fails with "Error Importing the Framework".  I was then hoping that there is something on the SQL side I could do to amend the framework but this has not exactly yielded any useful results.  Is there anywhere I can check for an error on the framework import?  If not is there any guidance on cutting a framework down to just the required fields?
