Hi! I'm currently working on a project for the "Steiermärkischen Landesbibliothek" (Styria, Austria) where we are migrating a rather big library into Koha. Now we've hit a problem, and I doubt that we're the first to do so, so I'd like to get some info on howtows/best-practice ... Currently we get bibliographic data out of the old system in MARC21-XML. This also contains various authorities e.g. authors that have a GND-ID. When doing a simple MARC21 import these authors are not created as autorities. But we would very much like them to be created as such :-) Is there anything obvious we are missing? Do we have to first import the autorities (stage-marc-import.pl seems to have an option for that)? Will a later import of bibliograpic data then create the correct links between biblio and authority? Or could we somehow handle this during the import of biblio-data (e.g. if MARC21 Field 100/0 is set, do a "find or create" on the value)? Or do we have to write some custom scripts that extract the relevant MARC21 data after the biblio import, and do the creation of authorities etc by ourselves? Or is there a contributed script somewhere that does that? I found this rather old thread: http://koha.1045719.n5.nabble.com/Building-authority-records-after-data-migr... which seems to indicate that there are no onboard Koha tools for such a migration. But as this post is from 2013 I hope that in the meantime this has changed?
