Originally proposed at Wikidata:Property proposal/Creative work

Done: alphabetical index (P11106) (Talk and documentation)

Description	initial letter or character of entries found at pages starting with qualifier value in this book with alphabetically ordered entries. Use applicable qualifier such as "page(s)" (P304), "file page" (P7668), "column" (P3903), "folio(s)" (P7416). If needed, "volume" (P478).
Data type	Item
Domain	dictionaries and other works ordered by alphabet
Allowed values	grapheme (Q2545446), and a qualifier, e.g., page(s) (P304), file page (P7668), column (P3903), folio(s) (P7416). volume (P478)
Example 1	Słownik „Dux-Liliput“ angielsko-polski (Q108959596) → A (Q9659), qualified with page(s) (P304) = 5 [1]
Example 2	Słownik „Dux-Liliput“ angielsko-polski (Q108959596) → B (Q9705), qualified with page(s) (P304) = 53 [2]
Example 3	Słownik „Dux-Liliput“ angielsko-polski (Q108959596) → C (Q9820), qualified with page(s) (P304) = 83 [3]
Example 4	File:Stanisław Goldman - Słownik Dux-Liliput.djvu → A (Q9659), qualified with file page (P7668) = 9 [4]

Discussion

Comment I could see a point to having a single-valued property that gives the page number of the start of an index, but having one value per letter? That seems excessive and unnecessary. ArthurPSmith (talk) 19:30, 7 December 2021 (UTC)[reply]
The sample one doesn't have an alphabetical index (and other similar ones where this property applies might not have that either).

In the paper version one just has to guess where the page is. It's generally feasible as one knows the size of the book. This is somewhat problematic once it's digitized. Possibly the reason why Wikisource created one in it's pages about the sample above.

@ArthurPSmith Maybe I misunderstood your suggestion. Can you do a sample? --- Jura 21:36, 7 December 2021 (UTC)[reply]
- Oh, I see you're trying to apply this to a dictionary or other work where most of the work is in some sort of alphabetical order? When I saw "alphabetical index" I thought you were referring to the location of the index in any work (many nonfiction books have an index section at the end). What I had in mind was "Nonfiction work" "alphabetical index starts on page" "355" or something like that. I think your label is at least confusing for this purpose; it also still seems of limited usefulness. ArthurPSmith (talk) 21:43, 7 December 2021 (UTC)[reply]
  The one you had in mind can be added with front and back matter (P8570).
  
  Apparently, contributors at Wikisource find it's needed, otherwise they wouldn't create it there.
  
  I agree that label isn't that great, but I couldn't come up with a better one. I suppose we can update the label if we find a better one. --- Jura 21:49, 7 December 2021 (UTC)[reply]
Comment following the comment by Arthur, I changed the label, maybe "entries with this initial start at qualifier value" is better than "alphabetical index". Where applicable, volume (P478) should be included as qualifier. --- Jura 09:11, 8 December 2021 (UTC)[reply]
Support it can be useful to enrich items of alphabetically-ordered works. --Epìdosis 14:15, 9 January 2022 (UTC)[reply]

@Jura1, Epìdosis, MasterRus21thCentury: I'm proposing a new label for this property, "has entries starting with" - this avoids having to mention the qualifiers in the label, and indicates that the work does have entries that start with the given letter which is a statement that can be understood whether or not there's a page number qualifier. We also may want to consider a "string" datatype rather than "item", to allow for arbitrary starting string values rather than purely letters or other strings that may have items? Anyway, further thoughts on this welcome. ArthurPSmith (talk) 19:23, 16 June 2022 (UTC)[reply]
This is an interesting feature that I find useful. Support --Gymnicus (talk) 17:07, 5 August 2022 (UTC)[reply]
Comment for your information, Han dictionary (Q1074045) is ordered by Chinese character radical (Q849778), which is not letter (Q9788). I guess grapheme (Q2545446) is more suitable for "allowed values". --Mzaki (talk) 12:27, 10 October 2022 (UTC)[reply]
