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.

Life stage edit

   Under discussion
DescriptionLife stage of an animal, plant, or other taxa
Data typeItem
Domainitem
Example 1Leptobatopsis mesominiata (Q2855459) has image (P18); needs qualifier life stage → adult (Q80994)
Example 2Chaoborus (Q2707905) has image (P18); needs qualifier life stage → larva (Q129270)
Example 3Tortula muralis (Q71869) has image (P18); needs qualifier life stage → sporophyte (Q647173)
Example 4Crocothemis nigrifrons (Q1318898) has characteristic (P1552) aquatic (Q441122) needs qualifier life stage → larva (Q129270)
Sourcephase of life (Q1811014)

Motivation edit

My primary use case is as qualifiers for images of individuals on commons, i.e. but this may also be used for if there is an item about a particular life stage of an animal, i.e. Chaoborus (Q2707905), which is an image of the larval stage, probably because the larval form is more well known, though in most species the adults form is more well known. Mvolz (talk) 13:14, 21 December 2022 (UTC)[reply]

Discussion edit

  • @ Mvolz: Can you fix up your examples so they look like Wikidata statements? They should have a subject item and then the value (which is presumably what your current list is of allowed values?) - if you intend this as a qualifier for images or something like that you may need to clarify more how it should be used. See other property proposals for how to do this. ArthurPSmith (talk) 19:42, 21 December 2022 (UTC)[reply]
@BlaueBlüte: We have a good number of items representing life stages of individual species, e.g. flaxseed (Q911332)      , mouse embryo (Q105811019)      , chicken embryo (Q70071341)      . There are also some that represent life stages for larger taxonomic groups, e.g. tadpole (Q168525)       or hatchling (Q2892050)      . --Daniel Mietchen (talk) 21:10, 30 January 2023 (UTC)[reply]

natural enemy edit

   Under discussion

Data typeItem

Example 3Engraulis japonicus (Q516676) -> Thunnini (Q6146274)

Motivation edit

If you look at Wikipedia's articles describing animals, you can see many of the natural enemies too. Through this, I wanted to describe the animal's natural enemies together. However, there was to "the food they usually eat", but there was no property to "their natural enemy." I think it would be good to add property to natural enemies. Thank you.

anthesis/flowering period start/end edit

   Under discussion
Descriptiontime of the year when a plant normally starts flowering
Data typeItem
Example 1Prunus cerasoides (Q150149)January (Q108)
Example 2Helleborus niger (Q147834)winter (Q1311)
Example 3Mentha pulegium (Q161235)≥June 13Mentha pulegium (Q161235)≤June 21
Example 4Mentha pulegium (Q161235)June 17 (Q2672)
Wikidata projectWikiProject Plants (Q10823481)

In case we stick with the data model as proposed, there would have to be a complementary property "anthesis end"/flowering period end", of course (as implemented with work period (start) (P2031)/work period (end) (P2032), start of covered period (P7103)/end of covered period (P7104), start time (P580)/end time (P582), date of birth (P569)/date of death (P570), ...).  – The preceding unsigned comment was added by Cartoffel (talk • contribs) at 20:16, 18 February 2024 (UTC).[reply]

Motivation edit

The time period when flowering is expected to happen is an essential information when describing a plant species. It is given in countless books, lists and databases. It is often relevant when trying to identify a plant, when trying to work out (potential) ecological interactions, when planning a garden, for bee keeping and what not.

  Question Would we have to introduce a new format for specifying such fuzzy time periods? For now, I am leaning towards specifying (several) calendar weeks (this would mean "data type": "item" and creating ~53 new items), but ideally, we would be able to precisely pinpoint the boundaries of a 95 % confidence interval using two points in time that represent the statistical spread of actual measurement values (so: two dates for the start of the time period and two for the end, assuming availability of relevant studies that analyzed enough of samples). See example #3 for my clumsy attempt. (Read: "In 95 % of cases, anthesis begins between June 13 and June 21.")--Cartoffel (talk) 20:33, 18 February 2024 (UTC)[reply]

‎leaf morphology, leaf shape edit

Motivation edit

Aspects of the leaf shapes are important identifying feature(s) of many plant species. Leaf shapes reflect essential evolutionary adaptations of the plant to its environment.

There is no good way to encode such essential plant data on Wikidata so far. Using has characteristic (P1552) seems to be the best we can do so far (e.g. Silene nutans (Q157950)has characteristic (P1552)lanceolate leaf (Q25501730)). Without dedicated properties, it would have to hold a lengthy list of pretty varied characteristics such as root shape, tuber formation, leaf vein patterns, leaf margin shape, growth habit, drought tolerance, fruit surface structure, ... Alternatively, with explicit reference to shape, we'd have to do more unwieldy statements like Silene nutans (Q157950)has part(s) (P527)leaf (Q33971)shape (P1419)lanceolate leaf (Q25501730), which need the useless, often redundant statement that a plant has leaves.

  Question Many databases have separate properties for e.g. leaf margin (entire, serrate, lobed, wavy, ...), leaf shape (lanceolate, elliptical, ovate, orbicular, needle-shaped, ...), leaf type (simple, compound, pinnate, sheath, frond, ...), leaflet count, leaflet shape, ... What would be the advantages for having several separate properties?--Cartoffel (talk) 23:58, 18 February 2024 (UTC)[reply]

Motivation edit

Featherbase (Q125117957) is a key resource for information related to feathers. It currently has information about ca. 1900 bird species, organized by taxonomic group and geographic location. They do not provide identifiers per se (other than for their "specimens") but their URL patterns are consistent enough to allow them to be used as such for practical purposes. The formatter URL contains an indicator of the language in which they provide information on the page. Currently, they have pages in English ("en"), French ("fr") and German ("de"), and I suggest to use the English one as the canonical version for the purpose of this Wikidata property. --Daniel Mietchen (talk) 21:37, 23 March 2024 (UTC)[reply]
