Where does it go?
Station Histories
Quality Measurements
Data Processing
Sensors
Extents
ParametersPeople
Levels of Documentation for OceanSITES
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 )
ISO Content
ncISO: Generating ISO metadata from NetCDF and THREDDS
Discovery: ncISO and the UDDC Service
Progress
ISO Integration with Geoportal
Improving Discovery Documentation
Work with Data Managers• Improve Content• Expand Content• Review guidance on the wiki and the role of
Unidata’s Data Discovery Convention• Harmonize UDDC and OceanSITES User
manual
Improving Content
Depth of Content: Is information missing from existing metadata?– Are all PI’s 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?
Remapping OceanSITES to UDDC Examples
• http://www.ngdc.noaa.gov/thredds/ncisoExamplesCatalog.html
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 link
Next Steps: Supporting Use Documentation
• Extending Existing Conventions – Deployment / Sensor / Lineage
• Incorporate into ISO• Incorporate OSMC ingest
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
