The idea is to allow for the detailed information as qualifiers, while using the "conflated" uncertainty for query answering. Ideally, for queries, we need a single value. The current solution would be use a single value plus a range of uncertainty for answering queries, so "Primates taller than 1m" will include a species said to be 90+/-20cm or something. -- daniel -- Daniel Kinzler, Softwarearchitekt Wikimedia Deutschland - Gesellschaft zur Förderung Freien Wissens e.
