To support any MARC flavour, NO MARC TAG/SUBFIELDS ARE HARDCODED into Koha.

The MARC export appears to call as_usmarc(), which needs MARC21 to be used to get valid results, doesn't it?

I spoke on Wednesday's IRC with jferraro (excuse misspelling) who was having some trouble with MARC export. Any progress?

Hi Mark, joshua tested the exported records with screen copy/paste. As there are some non-printable characters in iso2709, the result was wrong, of course. The as_usmarc() creates iso2709 records, not us_marc specifically ones. Let me explain how it's used in Koha : * the MARCgetbiblio() sub (a Koha one) builds a MARC::Record from Koha-DB. The MARC::Record in independant of the MARC flavour. * the as_usmarc() is applied on the MARC::Record object. It creates a valid iso2709 data. * some MARC::Record methods like $record->title() won't work. It returns the title that is located in 100$a in usmarc. In 100$a in UNIMARC is ... something else (don't remember). so Koha NEVER uses MARC::Record shortcuts like ->title or ->author. It uses an internal sub (MARCmarc2koha) that transforms a MARC::Record into an hash, having {title} being the title {author} being the author... Koha uses MARC parameter table to do this, so it's MARC flavour independant. * I think/am afraid extended char (é,è,à,...) are wrong. they are a pain in iso2709.
