Most definitely a great idea, avoiding having to convert data prior to upload. If I had the experience, I'd most certainly help with implementing this in Koha. I'm not even sure MARCEdit can handle, say, MADS => MARC21 at present, can it? I'll play around. Thanks all for the input! C Craig Butosi, MA, MLIS, B Mus (Hons.)

Agreed Tomas. I would love to see Koha have the ability to be 'format' agnostic when it comes to the data. On Fri, Jan 29, 2016 at 9:14 AM, Tomas Cohen Arazi <tomascohen@gmail.com> wrote:
There are (at least) two options:
- Make Koha handle more metadata formats (for authority records / thesaurus) and have the tools extract the needed heading for the bibliographic records - Make Koha handle importing SKOS-core packages into its authority database.
Those could work IMO.

I've been curious for a while now if anyone has successfully bulk-uploaded into Koha (3.20 or newer) one of the free LC Name authority database files available through the Library of Congress: http://id.loc.gov/download/
I wonder if it's even possible given the file formats in which these files are available (n-triples, rdf/xml, Turtle, etc). It looks like some sort of conversion would be required before uploading into the Koha authorities module. It would be lovely to bulk upload a Name authority file direct from LC rather than Z39.50'ing individual authorities.
This would be very positive. One of the problems is that the downloads available are not MARC, but are either MADS or SKOS. It seems as if converting these records to MARC would lose information, but I am not sure.
To see what this means, look at the record "United States--History--Civil War, 1861-1865--Bibliography" http://id.loc.gov/authorities/subjects/sh2007100437.html. If you select RDF/XML (MADS and SKOS) ( http://id.loc.gov/authorities/subjects/sh2007100437.rdf) this is what would need to be translated into MARC.
The guidelines for mapping MARC to MADS are at http://www.loc.gov/standards/mads/mads-mapping.html, and it says "This mapping gives equivalencies between the MARC 21 Authority Format and MADS, but is not intended to be a crosswalk that allows for bi-directional conversions without some loss of data. Where there is no equivalent MARC 21 element, this mapping says "no MARC 21 equivalent". Therefore, I assume there are some problems.
I don't know if anybody has experience with this, but I don't think the problems would be trivial.
