Why only for astronomical objects? / Pourquoi uniquement pour les objets astronomiques ?[edit]

--Gloumouth1 (talk) 09:49, 25 March 2013 (UTC)

When this property was proposed, it was done in the astronomical section. Nevertheless you are right: this property can be used also for other types of items. If there is consensus, I'm agree that it became "general". In this case, of course, we will need to change all the descriptions. --Paperoastro (talk) 13:27, 25 March 2013 (UTC)
Certainly support for things like dinosaurs or archeological objects. And perhaps even for ideas and theories, like "Einstein discovered relativity theory", that may not be the best possible word, but that may me simpler than creating another property. --Zolo (talk) 13:45, 25 March 2013 (UTC)
Move as general property. Snipre (talk) 14:32, 25 March 2013 (UTC)
Be careful if we generalize it completely, it shoud be renamed discoverer or inventor, in order to avoid:
  1. terminolgy discrepencies (e.g. in English, Lascaux was discovered, in French, it was invented)
  2. philosophically undecidable questions (e.g. were natural numbers discovered or invented?)
I think that few generic properties should be preferred to many specialized properties, but I'm not an expert in ontologies, and I'm afraid that there is currently no clear guideline about this.

Symbol support vote.svg Support generalization, but please be careful, as per Gloumouth1. --Ricordisamoa 15:21, 25 March 2013 (UTC)
Symbol support vote.svg Support This property clearly applies well beyond astronomy. Emw (talk) 03:45, 26 March 2013 (UTC)
Symbol support vote.svg Support if the label is renamed discovered or inventor --Gloumouth1 (talk) 10:17, 26 March 2013 (UTC)

Since there is consensus, I moved this property to generic section and changed labels and descriptions in English and Italian languages following the suggestions of this discussion. --Paperoastro (talk) 16:19, 26 March 2013 (UTC)

Same question / même question[edit]

Single value constraint[edit]

This does not make sense. A large part of all minor planet has a group of discoverer! -- Innocent bystander (talk) 18:56, 14 May 2017 (UTC)

What about things that were only invented but never discovered?[edit]

Vulcan (Q213636) was only hypothetical. But despite extensive effort, it was never discovered. Should I use a different property? --Shisma (talk) 08:29, 4 February 2018 (UTC)
