[Koha-devel] unimarc to marc21

Hi, I wonder whether it is possible to filter unimarc records retrieved from a Z39.50 server, and convert them "on the fly" into marc21 (and vice versa). Record_transform, a metaproxy module, claims to be able to perform such a conversion, but I couldn't figure out how to use it in conjuction with Koha. Many thanks, Giuseppe.
