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_WON

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
