I believe it would be more profitable to build a query system which always queries for the range. This would work for interval-only values (see my comment on the wiki page) as well as for value with interval. I don't see this as a big overhead. It is more a problem for ordering, but internally, wikidata could store a "midpoint" value for intervals where no explicit central value is given, and use these for ordering purposes. I think it would be great if the system is consistent for quantities, dates, geographical longitude/latitude, etc. Gregor _______________________________________________ Wikidata-l mailing list Wikidata-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata-l
