Difference

What's the difference between this property, based on (P144) and inspired by (P941)? Sjoerd de Bruin (talk) 10:12, 8 May 2015 (UTC)

Too much overlap.. Michiel1972 (talk) 22:50, 9 May 2015 (UTC)

See Wikidata:Property proposal/Creative work#after a work by. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:52, 9 May 2015 (UTC)

See Wikidata:WikiProject Visual arts/Item structure#Use of creator (P170) in uncertain cases. Multichill (talk) 12:23, 6 March 2016 (UTC)

This property should only be used when the subject item is essentially a copy of someone else's work. Typically used for paintings to acknowledge that it is a copy. Danrok (talk) 02:33, 22 September 2016 (UTC)

Qualifier

This property was supposed to be used only as qualifier. However, almost nobody does use it like that. Should we remove the qualifier constraint? @Spinster, Multichill, Coyau: --Pasleim (talk) 08:23, 2 September 2016 (UTC)

These errors were introduced in the last month.... Not a big fan of hijacking properties like this. Multichill (talk) 14:07, 2 September 2016 (UTC)

Qualifier? In which properties? It is counter-intuitive... --Infovarius (talk) 08:24, 9 November 2016 (UTC)

@Infovarius: Yes, on any property that holds some sort of creator indicating that that creator used another as inspiration. Check the proposal. Using it as a proper property makes no sense: if the work is based on another work, the work should be listed, and the creators of that work on the item of that work. The property may need a better name, but the way it is used on 5k+ items, is just badly structured data. – Máté (talk) 07:33, 10 November 2016 (UTC)

First I met this property (and I considered it useful) as a link to an author of literary work on which film is based (instead of screenwriter (P58) sometimes used), while for the work itself I'd use based on (P144) (additionally). --Infovarius (talk) 10:08, 10 November 2016 (UTC)

Why store it twice? It's already on the literary work's item, and it's easily extracted. Storing data twice should be avoided when possible. – Máté (talk) 15:06, 10 November 2016 (UTC)

The aim is to store in a right property. Because I met such authors in screenwriter (P58) frequently which is not absolutely correct. --Infovarius (talk) 09:57, 11 November 2016 (UTC)

On films, it seems a bit strange. Can it be removed?

Did you read previous sentence? --Infovarius (talk) 18:42, 30 November 2016 (UTC)

I don't think so. Probably I shouldn't have indented it that way. based on (P144) is sufficient.
--- Jura 07:14, 1 December 2016 (UTC)

At least not always - what if there are not items to which based on (P144) can point? --Infovarius (talk) 08:35, 27 June 2018 (UTC)
