Oh, 034 is new to me, but looks like a perfect match. Currently some
geoinfo is stored in https://www.loc.gov/marc/bibliographic/bd751.html

Yes, that's what I think too.

That's the plan

I guess "upgrading" a useful and working plugin to a Koha core feature
is easier than trying to implement it in Koha itself.

Thanks for the feedback!
