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

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
![Page 12: Documenting Data to Support Discovery and Use Dave Neufeld Ted Habermann John Kozimor](https://reader033.vdocuments.mx/reader033/viewer/2022052504/5514adf055034640138b4f4e/html5/thumbnails/12.jpg)
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
