Technically "truthy" is the set of statements with best non-deprecated rank for the property. Semantically, it is the value you most likely expect as the answer to a simple question "what is X of Y", like "what is the population of London" or "who is the wife of the US president?" > If I'm just a user of the data, because I want to retrieve > information about a particular item and link items with other > graphs... what am I missing/leaving-out by using "truthy" instead of > "all"? Historical data - i.e. current population vs. all historic population figures, current spouse vs.all previous marriages, current head of state vs. list of all people occupying the office. Some other data, possibly, such as official name vs. alias (provided that is expressed as a property), commonly accepted value vs. alternative possibilities, etc. > A practical example would be appreciated since it will clarify > things, I suppose. Current (as in, latest/best available for now) population of London would be found as "truthy" value (wdt), all other population figures - e.g. historical figures - will be under "all" (p/ps/psv). -- Stas Malyshev smalys...@wikimedia.org _______________________________________________ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
