OSFair2017 Workshop | SeaDataNet CDI catalogue service


Published on

Athanasia Iona presents the SeaDataNet CDI catalogue service | OSFair2017 Workshop

Workshop title: How FAIR friendly is your data catalogue?

Workshop overview:
This workshop will build upon the work planned by the EOSCpilot data interoperability task and the BlueBridge workshop held on April 3 at the RDA meeting. We will investigate common mechanisms for interoperation of data catalogues that preserve established community standards, norms and resources, while simplifying the process of being/becoming FAIR. Can we have a simple interoperability architecture based on a common set of metadata types? What are the minimum metadata requirements to expose FAIR data to EOSC services and EOSC users?

  2. 2. What is SeaDataNet? A pan-European infrastructure set up and operated for managing marine and ocean data in cooperation with the NODCs and data focal points of 35 countries bordering the European seas 2006-2011 Metadata directories MEDAR/MedAtlas 2002-2005 Sea-Search (FP5) 2006-2011 SeaDataNet (FP6) 2011-2015 SeaDataNet II (FP7) 2016-2020 SeaDataCloud (H2020) 90s
  3. 3. CDI service for discovery and unified data access European data sources data centres > 600 originators SeaDataNet portal Data centres Search and Shop Data download Metadata + transaction data Already 102 data centres connected and more underway
  4. 4. Linked Metadata directories with user interfaces (incl. map services) for search and display EDIOS CDI EDMED CSR EDMO EDMERP Projects Research cruises Observing programmes Data index Data sets Organisations
  5. 5. 1.95 million CDI entries from 34 countries, 102 data centres and 612 originators for physics, chemistry, geology, geophysics, bathymetry and biology; from 1805 to 2017; 87.6% unrestricted or under SDN License
  6. 6. Access to Products CENTRAL CDI Data harvesting File and parameter aggregation QC analysis Analysis of data anomalies SeaDataNet Quality Checks Strategy (QCS) Aggregated datasets and climatologies Improvement of the data quality Regional products • Products catalogue service • Products viewing services
  7. 7. Interoperability with global portals • CDI is available as OGC CSW, WMS and WFS service for exchange of CDI metadata • CDI is connected with GEOSS by CSW and IODE – Aggregation of SeaDataNet metadata CDI granules to CDI collections (ISO 19115 – 19139) (1.9 million => 500 collections), conversion to Common Brokerage Model, and harvesting via CS- W and OAI-PMH services

  9. 9. • Collaboration with EUDAT (engaged in European OpenScience Cloud) to establish a common cloud and computing environment that will be integrated with the SeaDataNet data management infrastructure to provide central caching and cloud computing facilities. Upgrading the CDI service using the cloud
  10. 10. Present SeaDataNet architecture Proposed upgraded architecture with data replication, advance services and VRE in the cloud
  11. 11. SeaDataNet/CDI Catalogue Service and FAIR principles • Provides highly detailed insight in geographical coverage and other metadata features of data across different data centres. • Visualization, transparent access to the discovered data via download services together with software tools for data/metadata process. • Use of common vocabularies, adoption of ISO19115- 19139 metadata standards in metadata directories ensures interoperability. • Delivery of data using common data transport formats.
