MultiSDO Information Modelling Workshop (Louisville, Colorado USA, January 13-14, 2016) Participating organizations named in alphabetical order: 3GPP, ATIS, Broadband Forum, DMTF, ETSI NFV, IETF, ITU-T SG15, MEF, OASIS/TOSCA, Open Cloud Connect, ONF, OpenDaylight, OPNFV and TM-Forum Useful information sharing across organizations concerning IM/DM affecting/affected by NFV, Collected a set of issues affecting “the ideal” IM/DM work outcome for NFV, agreed to meet again and share information on the progress of issue discussion. Presentations here.
