label

The English label part concerned is a bit confusing. I'd suggest changing it to applies to or applies to part. Danrok (talk) 23:30, 21 May 2013 (UTC)

applicable to may be best. Danrok (talk) 23:46, 21 May 2013 (UTC)

That sounds better indeed. I couldn't think of a nice label, thanks :). --Zolo (talk) 06:52, 22 May 2013 (UTC)

On second thought I am not so sure: it has to be clear that the property means "part of the subject item for which the statement applies". "Applies to" can probably have other meanings, like "EU directive: instance of law / qualifier: applies to: European Union". --Zolo (talk) 06:06, 23 May 2013 (UTC)

OK, if you think it should only be used in that specific way, then applicable to part. Danrok (talk) 13:44, 24 May 2013 (UTC)

Done. Actually, I cannot think of any example where it would be a bad thing to apply it in the sense "applicable to something else", but still, that is conceptually different, so I think it is best to be cautious and create two properties (better merge than demerge). --Zolo (talk) 06:59, 29 May 2013 (UTC)

I applied in Italian the same kind of modifications already applied in English and French, for the reasons expressed above. --FedericoMorando (talk) 21:31, 13 October 2020 (UTC)

Generalizing this property

It has been suggested to generalize this property with a new label "applies to" to be used in any context. Any objection or should we create a new property instead? See also: Wikidata:Properties_for_deletion#New_deletion_proposal.--Micru (talk) 13:14, 10 July 2014 (UTC)

Name change

This summer User:Swpb changed English label from "applies to part" to "applies to part, aspect, or form". I could not find any discussion that lead to that change, so I do not know why it was needed. However this expansion of the scope makes many of the current uses much harder to understand as you are trying to figure out what would "aspect" or "form" mean in context of a different objects. The issue is that concept of "parts" is rather clear: part of a country, part of a artwork, part of a vessel, part of a book. The issue with "form" is that the noun version of the word according to en:wiktionary:form has 12 different meanings some of which might be able to be applied to different types of objects, but likely not in way it was intended. "Aspect" is also a confusing term (with 12 different meanings) when applied to many types of objects. I think we need to change the label back to clear "applies to part". --Jarekt (talk) 13:13, 24 August 2020 (UTC)

The label change merely reflects longstanding use. The English description has long read "part, aspect, or form", and the property has hundreds of uses that are not "parts", for which this property has long been deemed most appropriate in the absence of another property. If there were an "applies to aspect or form" property, one could justify restricting the use of this property to strictly "parts", but as it stands, that would invalidate hundreds of statements. Swpb (talk) 14:34, 24 August 2020 (UTC)

Swpb I do not mind more nuanced description, I just find current label much more confusing than the original and I could not find any discussion where such big change was proposed and debated. Can you provide some examples of uses where "part" makes no sense but "aspect, or form" does? Because right now this discussion is very abstract and I have hard time understanding your rationale. Terms "aspect, or form" are so broad that this property suddenly could mean almost anything, making it much harder to pinpoint what do you mean. "Part of a building" is different than "form of a building". "Part of a valley" is quite different than "aspect of a valley". Do we now need qualifiers to describe which meaning is meant this time? It is a bit like naming property "width, area or perimeter". --Jarekt (talk) 22:06, 28 August 2020 (UTC)

@Jarekt: It's funny how any change one doesn't like is "big", and a change one likes is "trivial" – this property already covers these use cases among its aliases, so it didn't seem that big to me. And I think it's a tiny bit rude that after taking four days to reply, you didn't give me the same. But anyway, since you don't like extended label, I've proposed a new property, Wikidata:Property proposal/applies to form or aspect, which has the examples you asked about, of which there are many more. Swpb (talk) 19:46, 31 August 2020 (UTC)

Part of subject, or part of object ?

Does this qualifier indicate a part of the subject ? Or a part of the object of a statement ?

I'm not sure that it's always clear -- for example if applies to part (P518) is used in connection with based on (P144) / derivative work (P4969) to indicate that part of an original work has been used to inspire part of a derivative work (eg the top-left corner), is it clear which work that 'top left corner' is intended to refer to?

My understanding is that in most cases P518 should be read as applying to part of the subject of the statement.

I think we should make this definitive, and establish that P518 should be used only if it is a part of the statement-subject is being referred to -- and that in the (rare) cases where a part of the statement's object is meant, for that we should have and use a different property. I have therefore suggested Wikidata:Property_proposal/specific_part for the latter -- comments (and !votes) welcome! Jheald (talk) 21:29, 5 April 2021 (UTC)

I agree. At least in German the description explicitly referred to the statement subject since 2017 ("Teil des Subjekts, für das die Behauptung gültig ist"), only recently (April) this has been also made explicit in the label ("betroffener Teil des Subjekts"). This has been changed yesterday.

@Kolja21: You changed the property label and description yesterday to "betroffener Teil des Objekts" and "Teil des Objekts (item), für das die Behauptung gültig ist". Why? - Valentina.Anitnelav (talk) 08:58, 15 May 2022 (UTC)

Thanks for the ping. I know this property in its function as part of the item (= "Objekt" in German). This was the original label ("betroffener Teil") and description ("Teil des Objekts, für das die Behauptung gültig ist").[1] The property is needed if two authority control IDs are available for an item. Example: Q834448#P227 (see Help:P227). If P518 should be used in a different way we might need, like Jheald suggested, two properties. --Kolja21 (talk) 14:52, 15 May 2022 (UTC)

Thank you for your clarification! I read your new label in the light of property-pairs subject has role (P2868)/object has role (P3831), identity of object in context (P4626)/identity of subject in context (P4649), applies to name of subject (P5168)/applies to name of object (P8338) so that this property should indicate a part of the object (of the statement). Your example still supports the "betroffener Teil des Subjekts" ("applies to part of the subject") reading (The subject of the statements Q834448#P227 is Peace Palace (Q834448)). I changed the label back to "betroffener Teil" to prevent interpretations in line with "object of the statement". I guess an own property for the "applies to part of the object" may be useful. I like Jhealds inspired-by example.- Valentina.Anitnelav (talk) 08:10, 16 May 2022 (UTC)

@Nw520: "Teil des Subjekts (item)" … Was denn nun? Entweder Subjekt oder Objekt (item), vgl. Help:Objekte = Help:Items/de. --Kolja21 (talk) 15:29, 21 September 2022 (UTC)

@Kolja21: Die Diskussion habe ich nicht bemerkt, sorry dafür. Nach meinem Verständnis eigentlich Subjekt. Es gilt schließlich Subjekt - Prädikat - Objekt und wenn es nun heißt ⟨Irgendein Gemälde⟩ ⟨hat Farbe⟩ ⟨gelb⟩ (Qualifizierer:) ⟨betroffener Teil⟩ ⟨Rahmen⟩, dann ist ⟨Rahmen⟩ ja ein Teil von ⟨Irgendein Gemälde⟩ und somit des Subjekts. --Nw520 (talk) 21:09, 21 September 2022 (UTC)

Ich weiß nicht, wie man das Problem löst. @Emu: Kannst du mal auf die dt. Beschreibung schauen? --Kolja21 (talk) 22:42, 21 September 2022 (UTC)

Das Problem ist wohl, dass Objekt zwei Bedeutungen hat: Einerseits ist es die etwas unglückliche Übersetzung von „item”, andererseits wird es im Kontext der Subjekt-Objekt-Dichotomie verwendet (die für Anfänger ohne entsprechenden Hintergrund erfahrungsgemäß auch noch schwer verständlich ist). Die Formulierung „Teil des Objekts (item)“ löst zwar diese Unklarheit, jedoch um den Preis, dass sie eigentlich nur verständlich ist, wenn man Wikidata auf deutsch und auf englisch verwendet. Man könnte „Teil des Konzepts“ verwenden, aber da ist halt auch die Frage, ob das nicht mehr Verwirrung hineinträgt. --Emu (talk) 09:00, 22 September 2022 (UTC)

dass sie eigentlich nur verständlich ist, wenn man Wikidata auf deutsch und auf englisch verwendet

In das Problem bin ich reingetappt; meine erste Assoziation bei „Objekt“ ist die Bedeutung gemäß S-P-O.
In Wikis wird für den Verweis zum entsprechenden Artikel die Zeichenkette „Wikidata-Datenobjekt“ bei den Seitenwerkzeugen verwendet. Würde die Verwendung von „Datenobjekt“ statt „Objekt“ hier nutzen? Bei einer konsequenten Nutzung hätte man zwei unterschiedliche und somit unterscheidbare Übersetzungen für “item” und “object”. --Nw520 (talk) 11:20, 22 September 2022 (UTC)

Guter Vorschlag, da der Begriff "Datenobjekt" schon eingeführt ist. @Emu: Wieso wurde überhaupt "item" mit "Objekt" übersetzt? Ich kann mich an keine Diskussion dazu erinnern. Von Wikipedia her kommend, wäre "Artikel" naheliegender gewesen. --Kolja21 (talk) 01:46, 23 September 2022 (UTC)

@Kolja21 Etwas verspätet: Gute Frage. Du bist da sicher mehr Zeitzeuge als ich. Dazu kommt, dass ich Wikidata nie mit deutscher Benutzeroberfläche benutzt habe, ich bin da also eine ganz schlechte Ansprechsperson. --Emu (talk) 20:19, 1 December 2022 (UTC)

Query and get statements when P518

Hello, how in that Map of Istanbul Tram (query) query is possible to get the correct P625, eg https://www.wikidata.org/wiki/Q21527390#P625 Note that P518 is not in every item... Bouzinac ^{💬●✒️●💛} 08:15, 3 August 2022 (UTC)

Lexemes?

@Nikki: When adding a constraint limiting applies to part (P518) to Wikibase item (Q29934200) entities only, I found it was also used with a couple of lexemes (Joghurt (L310816) and Jogurt (L310817)) to differentiate between forms depending on grammatical gender (as main value of said forms, meaning the use was already in violation of the qualifier/reference scope constraint).

I suggest such differentiation should be made via the grammatical features list of each form instead. Or is this somehow not possible with noun forms?

If there is still a need to use applies to part (P518) on a lexeme, sense or form claim in a qualifier/reference scope, the appropriate entity types can of course be added. But right now I can't come up with a single practical example of such a claim. SM5POR (talk) 17:38, 24 October 2022 (UTC)

I didn't search thoroughly enough... I found some current uses as qualifier on lexeme claims as well, but they seem to differentiate between languages, not really what I would consider "parts" of a single lexeme. Aren't there other qualifiers more suited for this purpose? I'll leave the question open for now, pending somebody else's attention. SM5POR (talk) 18:14, 24 October 2022 (UTC)
