[ckan-discuss] Starting to populate datacatalogs.org

Thu Jun 23 15:18:10 BST 2011

Hi John,

The optional field called spatial coverage coords would be enough. Even, 
it could be a pair of "lat,long" values  (e.g., "38.36000,141.07546").

The URI field is more complex, but it would add added value to the 
representation. With the Geonames URI we can get information about the 
granularity of the spatial feature (city, region, country, continent, 
etc.). It also could be useful to enrich the data. Also, it contains the 
rest of the spatial fields values (label, countryCode, coords, etc.).

Best regards,

Martin
