Hi all! During my quest to add support for NORMARC (the Norwegian dialect of MARC) to Koha, I have come across several places[1] where UNIMARC is treated as the default if MARC21 is not specified. Here is an example from the subroutine GetMarcNotes in C4/Biblio.pm: 1268 if ( $marcflavour eq "MARC21" ) { 1269 $scope = '5..'; 1270 } else { # assume unimarc if not marc21 1271 $scope = '3..'; 1272 } When $marcflavour is "NORMARC" this fails, because NORMARC is more similar to MARC21 than to UNIMARC. I can think of two solutions to this: 1. Add NORMARC to the conditional: if ( $marcflavour eq "MARC21" || $marcflavour eq "NORMARC" ) { $scope = '5..'; } else { # assume unimarc if not marc21 $scope = '3..'; } 2. Reverse the logic: if ( $marcflavour eq "UNIMARC" ) { $scope = '3..'; } else { # assume marc21 if not unimarc $scope = '5..'; } I would prefer the second solution, because - in all the places I have found this situation it would be resolved by this solution, because NORMARC is so similar to MARC21 - as far as I know there are more MARC dialects that resemble MARC21 than there are dialects that resemble UNIMARC, so this solution would perhaps make it easier to add more dialects in the future If anyone has a completely different solution or pro/con arguments they would like to add I'm all ears! Regards, Magnus Enger libriotech.no PS. Just for the record: I'm no fan of NORMARC and would prefer if Norwegian libraries started using MARC21, but for Koha to be accepted in Norway it needs to support NORMARC...

Wouldn't a better solution be to build in a check for the syspref marcflavour, then act accordingly? I'm assuming you're adding NORMARC to that as an option. That might be more flexible in the long run, as others add other MARC variants. Jane Wagner Library Systems Analyst PTFS Inc.

Hi all!
2. Reverse the logic:
if ( $marcflavour eq "UNIMARC" ) { $scope = '3..'; } else { # assume marc21 if not unimarc $scope = '5..'; }
I would prefer the second solution
