Top of the evening Koha! I am working on ISO18626 with Koha and have been designing how to provide that feature for Koha. The RFC so far: https://wiki.koha-community.org/wiki/ISO18626_RFC If somebody is interested in joining our ISO18626 discussion this Friday the 6th, 15:00 UTC+0, please email me for the meet.jit.si-link. We will be discussing various issues regarding how to "make it happen". Best regards, Olli-Antti Kivilahti CTO Hypernova Oy
