Yes, exactly. > what value have to set for precision if I have just year (and no month > and day)? If you just have they yea, the precision value would be 9. This is arbitrary and obscure, sorry. I have filed a bug to fix this: https://bugzilla.wikimedia.org/show_bug.cgi?id=64593 For reference, here is the table of precisions to be used for time values, as defined in the TimeValue class: const PRECISION_Ga = 0; // Gigayear const PRECISION_100Ma = 1; // 100 Megayears const PRECISION_10Ma = 2; // 10 Megayears const PRECISION_Ma = 3; // Megayear const PRECISION_100ka = 4; // 100 Kiloyears const PRECISION_10ka = 5; // 10 Kiloyears const PRECISION_ka = 6; // Kiloyear const PRECISION_100a = 7; // 100 years const PRECISION_10a = 8; // 10 years const PRECISION_YEAR = 9; const PRECISION_MONTH = 10; const PRECISION_DAY = 11; const PRECISION_HOUR = 12; const PRECISION_MINUTE = 13; const PRECISION_SECOND = 14; If you have something like "between 1846 and 1855", you can use the "before" and "after" fields of the time value: time: "+00000001850-00-00T00:00:00Z", precision: 9, before: 4, after: 5 This means the "main" value is 1850, given as a year, with a lower bound four years before and an upper bound 5 years after the "main" value (before and after are given in the unit specified by the precision value). The "main" value is what is going to be displayed per default; it will also be used for sorting query results (once we have queries). This is a bit complicated, but should allow you to actually represent uncertain dates. We made it so you can be precise about the uncertainty :) HTH Daniel -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V. _______________________________________________ Wikidata-l mailing list Wikidata-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata-l
