Specify a coordinate system for latitude longitude? #216

Open BobHarper1 opened 7 years ago

I was reviewing #185 and noticed that we don't ask for lat/lon under a particular coordinate system.

I'd be assuming most publishers are going to use WGS84/EPSG:4326 (and those that currently do use it), but I've seen government bodies often use the OS/British National Grid format (sometimes referred to as Eastings/Northings rather than Lat/Lon, but synonymous) when publishing geographic data, often without specifying that this is the system being used.

So I ask, should we limit use of the coordinates fields location.latitude and location.longitude to WGS84?

Oh, and I just noticed that JSON-Schema has a canonical schema for coordinates http://json-schema.org/geo (just as a point of reference, I don't think it should change anything in our Schema)
