2. National Registry of metadata Goal – Joint metadata registry of resources in all Clarino centres Harvest data from all CLARINO centres Exchange data with other national CLARIN centres Status – current situation On-going and planned activities

3. 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 – http://metashare.nb.no/, proxied by the managing node http://metashare.tilde.com/ http://metashare.nb.no/ http://metashare.tilde.com/ – Metadata complying META-SHARE metadata format 3.0 – No harvesting facilities – Metadata content: 71 resources – Usage: 11.9.2013: 37 of the resources downloaded 1-17 times – Norwegian Wordnet (Bokmål) at the top – Topmost downloading locations: Norway, Germany, Greece, Sweden

7. 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

8. National Registry of metadata Planned activities Build a basic CMDI infrastructure – Repository, editor, search service, PID scheme, harvesting Convert metadata from META-SHARE to CMDI – Use META-SHARE profile as specified in Component Registry Extend/adapt metadata model according to need – In collaboration with the other CLARINO centres
