Hi Gavin,

For purposes of import, there isn't a useful distinction between
USMARC and MARC21 ... that is, if you have USMARC, you can import
into Koha as is and simply build your MARC framework to match the

MARC::File::XML is a tool that you could use to manage your records
if you decide to handle them in XML for some reason. Otherwise,
I'd use MARC::Record to do any pre-processing of the records.

Finally, I should mention that Koha 2.2.6 will include a much more
complete MARC framework (for MARC21) and I'd suggest using it as
a baseline for your framework (you can find it in rel_2_2 branch
of CVS).
