TEAM 3: Traditional Metadata Standards and Community Metadata

TEAM LEADER:  (Viderum/NextGEOSS data hub/Berlin)

PROJECT IDEA: The traditional metadata standards like Dublin Core, CDAT, GeoDCAT or ISO have limited schemas which are not sufficient for communities like climate or biodiversity researchers with their Essential Climate Variables or their Essential Biodiversity Variables (EVB.

Goal of the project is a proof of concept to enrich traditional metadata standards with the CKAN “system fields” mechanism so that

  • sources get additional information for EBV metadata while harvesting
  • harvested metadata can be filtered by EV content
  • APIs like OpenSearch can provide additional search criteria from the harvested EBVs
