Language

[edit]

Hello, are we really need specify language of work or name (P407) with this property? Language is already specified in monolingual type properties, language of work or name (P407) is looked redundant. Is original language of film or TV show (P364) means instead maybe? — Ivan A. Krestinin (talk) 22:22, 10 June 2015 (UTC)[reply]

I think so, I don't see language of work or name (P407) so necessary. ✓ Removed. --abián 20:26, 29 July 2016 (UTC)[reply]

Scope

[edit]

This could potentially also be used for scholarly article (Q13442814). Is that appropriate? — Finn Årup Nielsen (fnielsen) (talk) 15:39, 14 November 2016 (UTC)[reply]

I suppose that line does perhaps not make that much sense in prose compared to a sentence? — Finn Årup Nielsen (fnielsen) (talk) 15:42, 14 November 2016 (UTC)[reply]
I now see that it has been used for the famous first sentence of Pride and Prejudice (Q170583), - so it is used for prose. — Finn Årup Nielsen (fnielsen) (talk) 15:47, 15 November 2016 (UTC)[reply]
@Fnielsen: I agree to broaden the scope of this property. Cdlt, VIGNERON (talk) 17:16, 13 March 2017 (UTC)[reply]
@Fnielsen, VIGNERON: It certainly makes sense to expand its use to scientific articles, but should the first line refer to the first line of an article's abstract or the first line of the article proper? (e.g. should Analysis of Plasmodium falciparum diversity in natural infections by deep sequencing (Q20901697)'s first line begin "Malaria elimination strategies..." or "The genetic diversity..."?) Mahir256 (talk) 05:31, 24 June 2017 (UTC)[reply]
(@Hsarrazin, Innocent bystander, Visite fortuitement prolongée, Gymel, Sergey kudryavtsev, Pigsonthewing:, since you were all involved in the proposal of this property. Mahir256 (talk) 15:21, 25 June 2017 (UTC))[reply]
@Mahir256: not 100% sure but I would say "The genetic diversity...". Cdlt, VIGNERON (talk) 09:28, 24 June 2017 (UTC)[reply]
I do not at all oppose to widen the scope here! -- Innocent bystander (talk) 16:54, 25 June 2017 (UTC)[reply]
I have no strong objection but I'm not sure what purpose it would serve. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 20:24, 25 June 2017 (UTC)[reply]
I do not oppose to the broadening of the scope to scientific articles, but I fail to see what it would bring.... In poetry it is often the only way to distinguish between 2 poems with the same title, and many poems with no title at all, are just refered to by the incipit, whilst scientific articles generally have a very long and explicit title, so... --Hsarrazin (talk) 20:32, 25 June 2017 (UTC)[reply]
In poetry is obviously makes sense. For other works I am not sure, but I suppose that is not important. Future might bring us some ideas, e.g., text mining (non-negative matrix factorization (Q10843505) on the title and first line text) or data for text extraction applications, e.g., in case of Gutenberg raw text the start of the work is not clear as Gutenberg boiler plate obscures. — Finn Årup Nielsen (fnielsen) (talk) 11:28, 29 June 2017 (UTC)[reply]
For the scientific works I have done I have chosen to use the first sentence of the abstract, rather than the first line of the body text. When doing text mining I think you would be interested in the abstract and anything below. There seems to be no reason to excluded the abstract. The same goes for text extraction — Finn Årup Nielsen (fnielsen) (talk) 11:31, 29 June 2017 (UTC)[reply]

Is there any objection to add the version, edition or translation (Q3331189) to the type constraint? (or maybe further: only allow version, edition or translation (Q3331189)? it's seems a bit too far thought).

Reasoning: incipit can vary with the edition, for instance :

⟨ Roméo et Juliette (Q28761773)  View with Reasonator View with SQID ⟩ first line (P1922) View with SQID ⟨ Grégoire, sur ma parole, nous ne supporterons pas leurs brocards. ⟩
⟨ Roméo et Juliette (Q28938633)  View with Reasonator View with SQID ⟩ first line (P1922) View with SQID ⟨ Grégoire, sur ma parole, ils ne nous monteront pas ainsi sur le dos. ⟩

@VIGNERON: I would  Support this for all languages (which don't otherwise have items for their editions) other than that in which the original text is written. If a text has items for various editions and translations, then this property and last line (P3132) should be added to those. Mahir256 (talk) 05:50, 25 April 2017 (UTC)[reply]
Personally, I think that there should always be distinct item for book and the edition(s). And in this specific case I gave, the distinction is mandatory for Wikisource.
But, I understand that it can be difficult and we shouldn't be too pushy about that. I guess I'll leave the constraints as it is for now.
Cdlt, VIGNERON (talk) 11:26, 24 June 2017 (UTC)[reply]
 Support for adding version, edition or translation (Q3331189) to the type constraint, since different editions of a same poem can have different first line (P1922) - I already used it on different editions of the same poem with Renée Vivien (Q275628)'s poems :) --Hsarrazin (talk) 20:36, 25 June 2017 (UTC)[reply]

A few years later, I changed the constraint to explicitely accept both but to have more visibility, I started a discussion on Wikidata_talk:WikiProject_Books#P1922_for_work_or_edition?. Cheers, VIGNERON (talk) 15:01, 15 May 2022 (UTC)[reply]

Public domain

[edit]

Is this property only meant to be allowed for public domain entries? --RAN (talk) 19:00, 16 June 2021 (UTC)[reply]

@Richard Arthur Norton (1958- ): why would it be?
If it's for copyright reason, then I would say that a short quotation is not copyrighted (this is why we have Wikiquote for instance), but then we should focus on make sure the incipit are indeed kept short (in 2018 I raised it from 300 to 500 characters Special:Diff/635668128 but already it probably wasn't a good idea, later @Liuxinyu970226: raised it from 500 to 5000 and it sounds like a bad idea, then @Dhx1: lowered it to 1500 characters but isn't it too high? first most are already under 300 characters and, not just for copyright issue, incipit is supposed to be short by definition, no?).

Cheers, VIGNERON (talk) 15:14, 15 May 2022 (UTC)[reply]
@VIGNERON: The maximum of 1500 characters is a technical limitation of Wikibase as configured for Wikidata. I've added some references to the property constraint to state where the limitation exists. Dhx1 (talk) 22:56, 15 May 2022 (UTC)[reply]
