On hold till MediaWiki supports it?

Tracked in Phabricator
Task T97566

Do we already use this?

We can start to add the property to properties/items that could use it, but the info shouldn't be deleted from the description yet. Mbch331 (talk) 17:58, 29 February 2016 (UTC)

• Ok for me. Should this also be used as qualifier or only be there for notes that would eventually be covered by the MediaWiki function?

• I think it's probably best to leave it as a statement for now. If when it is supported it is supported as a qualifier then it should be a simple matter for a bot to convert them. Thryduulf (talk: local | en.wp | en.wikt) 13:37, 4 March 2016 (UTC)

• Sounds good. Support as I meant it would consist in MediaWiki displaying the text in the statement when adding a property or when using an item as value as it's currently being done with descriptions.
  As P2559 is currently not being displayed, we can duplicate the text from descriptions to statements with P2559, but we can't remove the text from descriptions yet.

Hmmm, at least I want it to be a gadget, but by searching MediaWiki (talk) namespace I can't believe that I can find that gadget. --Liuxinyu970226 (talk) 06:00, 5 April 2018 (UTC)
