  1. IOOS Registry and Metadata Improvement Options IOOS DMAC Workshop September 2013 ------------------------------------------------------------------------- Anna Milan NOAA, National Geophysical Data Center

  2. How does metadata get to the Catalog? Register Service in Collection Source Table CSW Search IOOS Catalog THREDDS Ncml Harvest Nightly SOS getCapabilities Synchronize daily to Geoportal Transform to ISO WMS getCapabilities ERDDAP iso ISO metadata in EMMA WAF iso

  3. Collection Source Table Register Service in Collection Source Table • Supports registration of: • THREDDS – Aggregated NetCDF • SOS – getCapabilities (sensor, station and networks – planned) • WMS – getCapabilities • ERDDAP – ISO metadata records • standalone WAFs – ISO metadata records CSW Search IOOS Catalog THREDDS Ncml Harvest Nightly SOS getCapabilities Synchronize daily to Geoportal Transform to ISO WMS getCapabilities ERDDAP iso ISO metadata in EMMA WAF iso

  4. Collection Source Table

  5. Service URL Configurations for Registry • THREDDS – register XML representation of the service http://tds.maracoos.org/thredds/MODIS.xml • SOS – register the SOS getCapabilities XML file http://d.weatherflow.com/sos/sos.pl?request=GetCapabilities&service=SOS • WMS – register the WMS getCapabilities XML file http://maps.ngdc.noaa.gov/soap/etopo1/MapServer/WMSServer?request=GetCapabilities&service=WMS • ERDDAP– register the ISO metadata WAF provided by service http://oos.soest.hawaii.edu/erddap/metadata/iso19115/xml/ • WAF – register the web accessible folder of ISO 19115-2 XML records http://oos.soest.hawaii.edu/pacioos/metadata/iso

  6. New Services ‘SUBMITTED’ service • Script runs nightly and posts results to a test WAF • Successful: NGDC changes status to ‘APPROVED’ • Unsuccessful: NGDC changes status to ‘UNRESPONSIVE’ OR ‘FAILSTRANSLATION’ • add notes to collection source table • contact provider of service to troubleshoot

  7. Harvest to EMMA* Register Service in Collection Source Table CSW Search IOOS Catalog THREDDS Ncml Harvest Nightly SOS getCapabilities Synchronize daily to Geoportal Transform to ISO WMS getCapabilities ERDDAP iso ISO metadata in EMMA WAF iso *

  8. Harvest of Approved Services to EMMA ‘APPROVED’ Services Metadata from each service is pulled nightly and translated to ISO 19115-2 ISO records are posted to EMMA WAFs organized by IOOS regions Generate quality and completion metrics Visualize metrics with reports and charts

  9. Metadata Metrics and Views

  10. Metadata Metrics for each region

  11. Demo http://www.ngdc.noaa.gov/metadata/published/NOAA/IOOS/GLOS/iso/

  12. EMMA helps you improve your metadata • Check validation • Check URLs • Use rubrics to increase your completion score • Use the Wiki guidance • Let us know what we can do to improve this guidance!

  13. Synchronize Metadata with Geoportal Register Service in Collection Source Table CSW Search IOOS Catalog THREDDS Ncml Harvest Nightly SOS getCapabilities Synchronize daily to Geoportal Transform to ISO WMS getCapabilities ERDDAP iso ISO metadata in EMMA WAF iso

  14. Geoportal

  15. Populate Catalog via CSW interface Register Service in Collection Source Table CSW Search IOOS Catalog THREDDS Ncml Harvest Nightly SOS getCapabilities Synchronize daily to Geoportal Transform to ISO WMS getCapabilities ERDDAP iso ISO metadata in EMMA WAF iso

  16. Catalog

  17. From Registry to Catalog Register Service in Collection Source Table CSW Search IOOS Catalog THREDDS Ncml Harvest Nightly SOS getCapabilities Synchronize daily to Geoportal Transform to ISO WMS getCapabilities ERDDAP iso ISO metadata in EMMA WAF iso

  18. Ideas and Plans for FY14 • Build better communication between registry and originators • Better guidance • Support Systems Integration Testing • Extend fields indexed in CSW • Provide metrics for Asset Inventory variables • Translate SOS sensor, network and platform metadata to ISO

  19. Resources • Collection Source Table • IOOS Metadata Metrics • On Demand Validation Services • Environmental Data Management Wiki (IOOS pages) • Enterprise Metadata Management Architecture (EMMA) Homepage
