"used as"?[edit]

Is this only "used as", or also "used for" (for example, an inhaler is used for inhalation)? --AVRS (talk) 15:44, 9 April 2013 (UTC)

Unsure. "Used for" is a useful thing to have but I am not happy with the structural inconsistency introduced by conflating the two things in the same property. --Zolo (talk) 11:59, 10 April 2013 (UTC)
I think I would say yes, as having two properties may be rather confusing, especially in a multilingual context, for no major advantages. Actually even common English usage tends to mix different types of relations ("office building" vs "mixed-use building"). --Zolo (talk) 20:19, 22 April 2013 (UTC)
"Used as" should be discouraged usage (Its just another way to say "is a") However, the aliased meaning of "Used in" and "Used for" should be encouraged usage of this property. Instead of "used as", you can think differently and actually restate with "instance of" or sometimes "subclass of". You can say A Movie is a class or form of Entertainment. But you can also say A Movie is "used for" "provides" Entertainment. Both would be correct, so it depends on context of the entities. Thadguidry (talk) 14:51, 7 July 2016 (UTC)

Residential use[edit]

Any ideas on which item we should use to indicate that a building is residential? There are many articles on wikipedia on the subjects of residential, housing, and so on. But, I don't see one which is an obvious fit for this property. Danrok (talk) 15:46, 16 May 2013 (UTC)

I think residence (Q699405) is alright (if as suggested above we use this proerty for both "used for" and "used as")

Other than buildings[edit]

It looks like the "use" property is not limited to buildings anymore. So, is using this property for other things allowed? --AmaryllisGardener talk 19:55, 28 October 2014 (UTC)

Inverse property[edit]

@Infovarius: If a knife is used for cutting, cutting is used by a knife ??? I don't get the inverse property you just set. author  TomT0m / talk page 13:05, 17 September 2015 (UTC)

Yes, I am wrong. I meant item operated (P121) vs Wikidata property example (P1855). Note that the scope of the first property was changed recently, I start the discussion. --Infovarius (talk) 14:08, 18 September 2015 (UTC)

drop the "main use"[edit]

  1. human (Q5) is used for transportation of various things, including infants
  2. used by (P1535) is not limited to "main use", I see no reason to limit use (P366) for whatever considered "main".
  3. "primary" can be modeled using qualifier series ordinal (P1545) = 1 (primary use), series ordinal (P1545) = 2 (secondary) and so on.

d1g (talk) 18:07, 14 March 2017 (UTC)

That use of series ordinal (P1545) is much too big a stretch. Swpb (talk) 17:16, 15 March 2017 (UTC)
Do we have a better property/qulifier to order values? d1g (talk) 23:16, 17 March 2017 (UTC)

I have to admit that Q5, Q32489 and Q11748378 would have many uses (seval thousands), not just hundreds. It should be possible to enter a dozen/hundeds of uses to something specific and rare. My reasoning is that it is easier to populate single item ATM, not hundreds. d1g (talk) 23:16, 17 March 2017 (UTC)

Expand subject constraint[edit]

I'd like to add Q28165751 as a subject type for this property - see pouncing (Q3493717) for an example. - PKM (talk) 01:54, 1 December 2017 (UTC)

Actually, I'd like to go one step up the class hierarchy and add process (Q3249551) instead. Processes “use” tools and other processes. - PKM (talk) 04:47, 1 December 2017 (UTC)
No. Many, probably most, items with "use" are not processes. use (P366) is used on tons of objects, for example. Swpb (talk) 18:27, 1 December 2017 (UTC)

Property usage for software[edit]

While editing software items I came across different approaches to define the main use of an application. Some entries use instance of (P31) to describe the aim of the software (e.g. ontology editor (Q453843) or word processor (Q54277)). This can be found in Microsoft Word (Q11261) or in Protégé (Q2066865). Others like the entry of Wikibase (Q16354758) define the aim with use (P366). Could you indicate you would see the correct use of use (P366) in this case? Is use (P366) intended to describe the aim of software? Katjos (talk)
