Wikidata:Property proposal/Smithsonian trinomial prefix

Originally proposed at Wikidata:Property proposal/Place

We probably need to store this. And we should probably do that independently from Smithsonian trinomial (P3518), to avoid confusion as to what is a working trinomial and what's not. Our friend Flathead County (Q496607) gets 24FH because the trinomials for sites in that county are all written as 24FHn where n is a number with one or more digits. J.K. Miller Homestead (Q14704570), for instance, got trinomial 24FH333. Thierry Caro (talk) 15:47, 23 April 2021 (UTC)[reply]

•  Comment Good idea. Given the table at Wikipedia showing varying formats per state, I wonder if we shouldn't store a regex instead, e.g.
  • Belknap County (Q54442) → 27-BK-\d\d\d\d
  • Flathead County (Q496607) → 24FH\d\d\d\d
  • South Carolina (Q1456) → 38‑[A-Z][A-Z]‑\d\d\d\d
  • Rhode Island (Q1387) → RI‑\d\d\d\d

for the samples above + RI. --- Jura 14:03, 14 May 2021 (UTC)[reply]

@Thierry Caro, Jura1: it is not clear to me what 24FH\d\d\d\d means. If it is a regex so it matches only string like 24FH1234 but 24FH333 will not match. So if the number of figures is between 0 and 4, it should be something like 24FH\d{0,4}. Is it what you meant? Pamputt (talk) 06:26, 22 July 2021 (UTC)[reply]

One more question, where can we find such code? Is there any website or somewhere else? Pamputt (talk) 06:27, 22 July 2021 (UTC)[reply]

The regex above is based on the Wikipedia article. Apparently the value for J.K. Miller Homestead (Q14704570) doesn't match that. I think we will have to finetune the values and cross-check with complex constraints. --- Jura 09:37, 22 July 2021 (UTC)[reply]
