National Registry of metadata Status (1) Metadata registry version 1 is running – Search/browse, editing and management, but no harvesting facilities – Infrastructure: META-SHARE infrastructure 3.0 – proxied by the managing node – Metadata complying META-SHARE metadata format 3.0 – No harvesting facilities – Metadata content: 71 resources – Usage: : 37 of the resources downloaded 1-17 times – Norwegian Wordnet (Bokmål) at the top – Topmost downloading locations: Norway, Germany, Greece, Sweden

National Registry of metadata Status (2) Decision made: Migrate to CMDI (CLARIN platform) – Uncertain future for META-SHARE 2 ys guaranteed life span – Need for more adaptability and expressivity in metadata model – Increased involvement with the CLARIN community
