Based on the feedback so far I have frozen the datatype for time [1] and updated the datatype for coordinates. There are now two distinct members:
* precision: which actually means the precision in the representation, i.e. by the degree or arcsecond, etc., and which is used to calculate different representations * dimension: which represents the "size" of the object / target area in meter, and which can be used to choose the scale for a map or to represent uncertainty about the coordinate [2] The dimension parameter is based on the work of Max Semenik in the GeoData extension and recognized as a solution to the discussion that happened here on the list. If you have any further comments on the datatype for coordinates, say so here. Otherwise I will move to quantities next :) Cheers, Denny [1] <http://meta.wikimedia.org/wiki/Wikidata/Data_model#Dates_and_times> [2] < http://meta.wikimedia.org/wiki/Wikidata/Development/Representing_values#Coordinate > [3] <https://www.mediawiki.org/wiki/Extension:GeoData#Glossary> -- Project director Wikidata Wikimedia Deutschland e.V. | Obentrautstr. 72 | 10963 Berlin Tel. +49-30-219 158 26-0 | http://wikimedia.de Wikimedia Deutschland - Gesellschaft zur Förderung Freien Wissens e.V.
