See also[edit]

This page is for the proposal of new properties.

Before proposing a property

  1. Check if the property already exists by looking at Wikidata:List of properties (research on manual list) and Special:ListProperties.
  2. Check if the property was previously proposed or is on the pending list.
  3. Check if you can give a similar label and definition as an existing Wikipedia infobox parameter, or if it can be matched to an infobox, to or from which data can be transferred automatically.
  4. Select the right datatype for the property.
  5. Start writing the documentation based on the preload form below and add it in the appropriate section.

Creating the property

  1. Once consensus is reached, change status=ready on the template, to attract the attention of a property creator.
  2. Creation can be done 1 week after the proposal, by a property creator or an administrator.
  3. See steps when creating properties.

Hi, I proposed Wikidata:Property_proposal/Transportation#nombre_de_passagers_par_an but it seems more complicated and less clear than I expected, I suppose it will finally be dropped. I then propose to have a total of 3 properties for clientèle/patronage : a total (existing patronage (P3872)), an international subtotal (subject of this property proposition), and if the international is accepted, then a domestic/national subtotal property would also be proposed and created. So that international+national = total patronage (P3872). Context : this data is often available for airports, and probably for international train stations (Eurostar, Thalys, etc).

This could be considered redundant to something like length (P2043) (journey time) + duration (P2047); but regardless of whether new redundant properties are considered acceptable, the new property would allow either of those two properties' value to be inferred where only two measurements for the same point in time can be sourced.

    @Pasleim: "Cruise speed", to my understanding, is the design speed for the state in which a plane or other vehicle isn't accelerating or decelerating, assuming "normal" factors such as no headwinds/tailwinds. This is different from the property proposed here; the existing property is for vehicle types, whereas this property would be for fixed transport services (or for types of vehicles on such services, if applicable).

Change the datatypes of yard number and call sign[edit]

yard number and call sign are currently locked to the "string" type, but they are in fact external identifiers by definition. So I think it would be prudent to set these two properties to "external identifier". De728631 (talk) 15:42, 27 April 2019 (UTC)

@Thierry Caro, BukhariSaeed, Obaid Raza: who might find this interesting.

Why can't be used station code (P296) with a qualifier? --Sabas88 (talk) 09:43, 27 August 2018 (UTC)

@Sabas88: If you would like to propose the deletion of the other four properties I mentioned (plus more of the sort), you are welcome to do so, but in the meantime having a separate property for this large collection of stations has its benefits, including the ability to easily define formatter URLs for each country on each country's respective property.

Without references, I'm afraid that your sentenses can be mostly empty sentenses. --Liuxinyu970226 (talk) 12:07, 6 October 2018 (UTC)
    @Liuxinyu970226: There are items for rail stations in Pakistan, such as Lahore Junction railway station (Q3695748) (hey, you edited that item!) that presently have a station code (P296) (derived from their respective enwiki articles) which could be converted to use this property. One can also derive lists of codes from old versions of the Pakistan Railways site (this does not mean that the codes are unused presently!--see page 6 here of a recent timetable).

  • Symbol oppose vote.svg Oppose for now, unless there's a use of this in URLs; at the moment, I can't find any uses of these codes in URLs anywhere on the web, not even on .

Especially it could be useful for the buses because there is a huge amount of item about bus chassis (see here) but we don't use them. Well, we use them but only for the follows (P155)/followed by (P156) properties. This brand new property could be a great usage for them and it would be useful useful for the Wikipedias' infoboxes importing the data from the Wikidata. As I mentioned this would be good for cars and trucks too but at the moment only few car chassis has Wikidata item and there isn't any truck chassis. – balint36 🚌 bus stop 20:09, 17 January 2019 (UTC)

tend to Symbol oppose vote.svg Oppose, it seems enough to use has part (P527) for this. The subclass of (P279) claim of the object of the claim will be enough to know that the object is a chassis (in sparql, ?chassis_model wdt:P361 wd:Q24908099 ; wdt:P31 wd:Q23034867 or ?chassis_model wdt:P361 wd:Q24908099 ; wdt:P279* wd:Q[the « chassis » item id] can do that. This works for all the other types of parts. author  TomT0m / talk page 17:53, 21 January 2019 (UTC)
The problem using has part (P527) is later we (especially the beginners) won't be able to make difference between the the chassis and the engines (the other part). For example: Volvo uses similar names for engines and chassis (Volvo D8K vs. Volvo B8R I bet you can't tell which is the engine and which is the chassis) so it will be confusing to a beginner seeing on the Volvo 8900 (Q2639800) that the bus contains Volvo D8K, Volvo B8R, Volvo B8RLE. Then using has part (P527) instead an own property makes harder to read the type of the chassis from the Wikidata on many Wikipedias. And finally storing all parts of the vehicle in one peoperty is unnecessary. The question is what kind of other types of parts we want. We don't care the type of the windscreen or the type of the tires. The two parts we need are the chassis and the engine. The engeine already has an own property (powered by (P516)). So what remains in the has part (P527)? – balint36 🚌 bus stop 01:29, 22 January 2019 (UTC)

from Ride height (also called ground clearance or simply clearance) is the amount of space between the base of an automobile tire and the lowest point (typically the axle); or, more properly, to the shortest distance between a flat, level surface, and the lowest part of a vehicle other than those parts designed to contact the ground (such as tires, tracks, skis, etc.). --LucaBiondi (talk) 20:30, 28 November 2018 (UTC)
