Build a spreadsheet for the ESGF mapping from SOLR to STAC

[agstephens]

• Tab 1: CMIP6 Dataset (Item)
• Tab 2: CMIP6 File (Asset)

We might want separate CMIP5 tabs as well - but hopefully not.

Refer to table 2 in the ESGF Future Architectures: https://zenodo.org/record/3928223

Two points to consider:

1. Can we remove some metadata/properties?
2. Are there some properties we should add?

To consider:

• Schema.org tags:
  • Refer to Google dataset search: https://datasetsearch.research.google.com/search
  • What else might we want to tag? Are there any NERC standards for this?
• ES-Doc content
  • Is there any utility in pulling in ES-Doc content? Rather than including links out to ES-Doc?
• date/time object for temporal search
• Bounding box (geospatial constraints)
• DOI (Citation) 1..n:
  • unlikely that Item or Asset has a unique DOI - they live at model or experiment level
• Errata content:
  • maybe we would link in the user interface rather than in the catalogue
