Notes	Only fails if all of the relevant fields of the Darwin Core Location class are EMPTY or do not exist. Relevant Darwin Core fields include dwc:locationID, dwc:higherGeographyID, dwc:higherGeography, dwc:continent, dwc:waterBody, dwc:islandGroup, dwc:island, dwc:country, dwc:countryCode, dwc:stateProvince, dwc:county, dwc:municipality, dwc:locality, dwc:verbatimLocality, dwc:decimalLatitude, dwc:decimalLongitude, dwc:verbatimCoordinates, dwc:verbatimLatitude, dwc:verbatimLongitude, dwc:footprintWKT. Elevation and/or depth alone are deemed insufficient to meaningfully locate a position on the earth.

Comment by Paula Zermoglio (@pzermoglio) migrated from spreadsheet:
I believe DwC terms should include some more, e.g., island, islandGroup, waterbody, county, municipality, continent, countryCode.

This is a complicated test - needs more work to document. Not georeferenced or not georeferenceable.. Need to add many dwc:terms. If all relevant spatial terms are blank or uninterpretable.

Extensive discussion in the meeting - has georeference or is georeferencable is one possible interpretation, but a very complex one to implement, and supported by other more granular tests. We decided to constrain this test to a simple test of minimal presence of some sort of spatial data.
