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
National Registry of metadataStatus (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/
– 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
National Registry of metadataStatus (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
National Registry of metadataPlanned 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

Long term archiving
Time perspective
• Metadata registry version 2 : Primo 2014– Basic CMDI infrastructure
• existing metadata converted from META-SHARE
• OAI/PMH endpoint, but no harvesting from other centres
• Metadata registry version 3: Mid 2015– Extended/adapted metadata model– Harvesting from other CLARINO centres
• Long term archiving: Mid 2014 with both data and metadata.
