Hey,
I have some questions/remarks on the "Complete Datamodel in WON" section Markus wrote up yesterday: https://meta.wikimedia.org/wiki/Wikidata/Data_model#Complete_Datamodel_in_WO...

GeoCoordinatesValue := 'GeoCoordinatesValue(' decimal decimal
decimal ')'
Altitude is probably something we will not have in many cases, so I think this ought to be optional. Another optional argument would be the globe to which the coordinates belong.
Agree and there should be a default coordinate system such as EPSG:4326 ( http://spatialreference.org/ref/epsg/4326/).
Different globes have different ways of measuring coordinates, so a specific set of coordinates that is valid on one might mean something else on another and simply be invalid on a third.
Agree with that.
And I think it should be GeoCoordinateValue, not GeoCoordinatesValue.
Cheers, Katie
Cheers
