Highlights Progress Current workflow Common property meanings eases multiple dialects Improving metadata content Federated searches ISO DS_Series Support Collaboration Wiki Locator services Google code shared repository? Next steps Integrating ontology services for ocean communities Keywords tag cloud
Current Workflow NGDC Geoportal went live on December 22nd, 2011 o Over 15,000 records o Mixed content RDF, FGDC, and ISO-2 o Web Accessible Folder (WAF) centric model WAFs FGDC F ncISO ISO-2
Common Property Meanings Expanding the shared conceptual model o property-meanings.xml Simplifies modifications to search page Enhances customized links in results keywords startDate endDate title distribution Links Service Types geometry
Common Property Meanings Example startDate / endDate: FGDC <property meaning="startDate" xpath="/metadata/idinfo/timeperd/timeinfo/rngdates/begdate"/> <property meaning="endDate" xpath="/metadata/idinfo/timeperd/timeinfo/rngdates/enddate"/> ISO-2 <property meaning="startDate" xpath="/gmi:MI_Metadata/../gmd:extent/gml:TimePeriod/gml:beginPosition"/> <property meaning="endDate" xpath="/gmi:MI_Metadata/../gmd:extent/gml:TimePeriod/gml:endPosition"/>
Metadata Improvements Working with data providers key to success! IOOS OceanSITES UAF
DS_Series (indexables/definition xml) Network/Collection Level Metadata
Collaboration http://geo-ide.noaa.gov/wiki/ Information sharing with NODC speed deployment process Working with ESRI/USGS on ISO-2 and THREDDs GEO-IDE wiki to share Progress Improved locator services Google code base
Next steps Collaborate with OOI for ocean ontology services Continue work with ESRI on improved THREDDs harvesting Integrating metadata tag clouds Focus on lineage and sensor metadata
