Units

[edit]

The example says 10200 km but on the property page the example uses 10200 miles. In general I think we should stick to SI units for measurements that were made after SI was commonly used around the world ~1800. The reason is this: Currently queries to the database will just return which ever value is in the statement. If some of these values are km and some of them miles we can't really use this propety until advanced filtering and querying are possible. So if we wan't to use this property for example for lists, we need to keep the output consistent. --Tobias1984 (talk) 08:54, 16 September 2015 (UTC)[reply]

Please see Wikidata:WikiProject Aviation/List of Boeing airplanes for what I am talking about. The unit is not part of the returned value at the moment. If we do just km, we at least know what we are getting. --Tobias1984 (talk) 09:00, 16 September 2015 (UTC)[reply]

Other things than vehicles

[edit]

This is currently limited to vehicle (Q42889). But this property would also be useful to anything that emits something else, like a signal (Q1412443) for example. On the French version of Template:Infobox lighthouse (Q13384512), we have a line to document how far the light emitted by the said lighthouse can reach. This property might be used there, or am I totally wrong? Thierry Caro (talk) 12:01, 23 September 2015 (UTC)[reply]

Seems of different nature as a lighthouse does not move ... Imagine someone creates a mobile lighthouse some day :) This would not work. author  TomT0m / talk page 12:22, 23 September 2015 (UTC)[reply]
I guess a mobile lighthouse is a sun! Thierry Caro (talk) 12:46, 23 September 2015 (UTC)[reply]
More seriously maybe you are right. Missiles or cars can have a range for themselves and a different one for their signal or whatever they may emit. But then do we really need another property or is that OK with qualifiers? Thierry Caro (talk) 12:48, 23 September 2015 (UTC)[reply]
I think there are at least two or three other concepts that we should not attempt to combine with this:
  1. "range of light, sound or signal" for lighthouses, TV/Radio transmitters, wi-fi signals, speakers, two-way radios, radar, etc.
  2. "accurate to range" for missiles, projectile weapons, etc. where the projectile or whatever may travel a lot further than the range within which it can be accurately targeted.
  3. "accurate within range" for measuring devices or scales, e.g. a specific model of sound meter is advertised as being accurate within the range 35-165 dB.
1 and 2 are to me clearly distinct concepts from the range of a vehicle without refuelling, but I'm unsure whether 2 and 3 are distinct from each other or not. Thryduulf (talk: local | en.wp | en.wikt) 12:32, 8 June 2016 (UTC)[reply]
