This page is for the proposal of new properties.

Before proposing a property

  1. Search if the property already exists.
  2. Search if the property has already been proposed.
  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. Read Wikidata:Creating a property proposal for guidelines you should follow when proposing new property.
  6. Start writing the documentation based on the preload form below by editing the two templates at the top of the page to add proposal details.

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 creation of the proposal, by a property creator or an administrator.
  3. See property creation policy.

Motivation

[edit]

The specific combination of catalog code (P528) qualified by catalog (P972) is used in 24 million statements, the vast majority of which are for astronomical objects. About 14 million of these statements come from six catalogues, so migrating those statements to use these properties would remove the 14 million triples taken up by the P972 qualifiers. (Another 18 catalogues have more statements than the number of statements for inventory number (P217) with qualifier collection (P195) The Palace Museum (Q2047427)—127545 as of 6 August 2024.)

(This migration would similar to the migration that took place after the properties proposed at Wikidata:Property proposal/proper motion components were created. While this page intends to handle only the six largest catalogues, if you believe there are other large catalogues whose catalog codes would do well to be migrated to properties, please say so in a comment.)

@Mahir256 Is there any specific reason why we want to reduce number of P528 statements? Ghuron (talk) 00:03, 7 August 2024 (UTC)[reply]

Discussion

[edit]
As stated by Ghuron, is there any reason why we need to reduce the number of P528 statements? In the first place there are millions of Gaia IDs because of the import of the Simbad database (I am NOT against this import btw).
Also, I wonder why only some catalogues would have their own properties. This will create a weird in-between for catalogues in P258 vs catalogues having their own properties. This makes no sense imo.
Romuald 2 (talk) 15:31, 8 August 2024 (UTC)[reply]
  • There is nothing wrong with having separate external id properties for most used identifiers with the correct "url formatter".
    But I have 2 major objections:
  1. I don't see any reason to use https://simbad.u-strasbg.fr/simbad/sim-id?Ident= as a url. Those items that are on simbad, we already have Property:P3083 with the link to simbad. Those rare items that are not on simbad, this link will result in 404
  2. Having in mind (1) it would make sense to link to really useful external storages, that are only partially synchronized with simbad (like HyperLEDA or Gaia Archive). And that leads us to question about proposed set of properties:
    1. Why did we choose Gaia DR2, because this is only temporary IDs, permanent are Gaia DR3?
    2. Why did we choose Tycho-2, they pretty much 100% imported in Simbad?

This would be aimed at taxon but could apply to other things as well.  – The preceding unsigned comment was added by AHIOH (talk • contribs) at 02:59, August 1, 2024‎ (UTC).

  •  Comment I see we have real GDP growth rate (P2219) and I guess it would make sense to have a more generic version. However I'm dubious about this proposed application - living things don't grow at a uniform rate over time, generally? And for example for plants I would expect it to be hugely environment-dependent. So - we could use a generic property like this I think, but I'd like to see more realistic examples of how it would be used. ArthurPSmith (talk) 19:39, 1 August 2024 (UTC)[reply]
    I agree, the real GDP growth rate (P2219) as other types of growth rate could potentially be a sub-property of this if it were generalized. This would also reduce the need to create new properties related to growth rate for each aspect of every subject.
Regarding the rate of growth for living things, there appears to be multiple metrics/methods used. One common method that appears to be used is Relative growth rate (Q7310793) however this doesn't appear to be inclusive of all the common ways of relating the growth rate of something.
As you mentioned there are a variety of factors that go into the what the growth rate entails. These would likely be refined using qualifiers such as valid in place (P3005) environment (Q2249676), point in time (Q186408), etc
This could be used for both documented cases of growth over a period of time as well as expected rates based on statistical models.
As far as the implementation it would likely be good to require references and possibly determination method (P459). Rather than define this as an average it might be good to require a nature of statement (P5102) or similar.
This proposal was originally aimed at growth rates of taxon, however for this proposal I think it's better to focus on the generalized growth rate property which could be used in the interim for a variety of use cases rather than limiting to creatures, taxon, etc. I think a separate proposal for "Taxon growth rate", "Plant growth rate", "Animal Growth Rate", and other sub-properties could then be created in cases where there are a common or limiting set of factors that apply.
