1. Documenting Data to Support Discovery and Use Dave Neufeld Ted Habermann John Kozimor

2. Where does it go? Station Histories Quality Measurements Data Processing Sensors Extents Parameters People

3. Levels of Documentation for OceanSITES

4. Content Distribution Usage Discovery Program (OceanSITES) Network (ESTOC, LINE, MBARI, TAU) Platform (M0, M1, M2,) Deployment (MO-04 M-05, MO-06, MO-07) Sensor (Current Profiler, CTD, CO2 Analyzer, Flurometer, Spectroradiometer )

5. ISO Content

6. ncISO: Generating ISO metadata from NetCDF and THREDDS

7. Discovery: ncISO and the UDDC Service Progress

8. ISO Integration with Geoportal

9. Improving Discovery Documentation Work with Data Managers Improve Content Expand Content Review guidance on the wiki and the role of Unidatas Data Discovery Conventionwiki Harmonize UDDC and OceanSITES User manual

10. Improving Content Depth of Content: Is information missing from existing metadata? –Are all PIs included in the program level record? –Are all network contacts included in network level record? Breadth of Content: Is the standard utilized to the fullest? –Is the data processing workflow described? –Are quality reports included? –Is the instrumentation described? –Is platform/instrument maintenance documented? Organization of Content: Is information documented at the correct level?

11. Remapping OceanSITES to UDDC Examples http://www.ngdc.noaa.gov/thredds/ncisoEx amplesCatalog.htmlhttp://www.ngdc.noaa.gov/thredds/ncisoEx amplesCatalog.html

12. Expanding Content NetCDF Conventions UDDC CF Importance of Titles, Keywords, Abstract Lineage Quality Instrumentation WHOTS as a starting point for discussion on evolving conventions to include sensor level info: WHOTS Example linkWHOTS Example link

13. Next Steps: Supporting Use Documentation Extending Existing Conventions –Deployment / Sensor / Lineage Incorporate into ISO Incorporate OSMC ingest

14. Documentation Hierarchies Enable objects to be grouped by scope (level) Enable levels to be related or connected by hierarchy order Produce a comprehensive documentation structure Produce a complete archive information object

15. ISO Examples Complete Hierarchy http://www.ngdc.noaa.gov/metadata/published/NOAA/OAR/OCO/oceansites/iso_series/xml/oceansites_seriesV2.xml Program Level http://www.ngdc.noaa.gov/metadata/published/NOAA/OAR/OCO/oceansites/network/xml/antares.xml Network Level http://www.ngdc.noaa.gov/metadata/published/NOAA/OAR/OCO/oceansites/network/xml/antares.xml Platform Level http://www.ngdc.noaa.gov/metadata/published/NOAA/OAR/OCO/oceansites/platform/xml/antares-1.xml Deployment Level http://www.ngdc.noaa.gov/metadata/published/NOAA/OAR/OCO/oceansites/deployment/xml/antares-1_200509.xml Sensor Level http://www.ngdc.noaa.gov/metadata/published/NOAA/OAR/OCO/oceansites/sensor/xml/antares-1_200509.barometer.xml
