|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Represents | drainage basin (Q166620) | ||||||||||||
| Data type | Item | ||||||||||||
| Domain | Any geographical feature (Q618123), and first of all any body of water (Q15324) (note: this should be moved to the property statements) | ||||||||||||
| Allowed values | Instances of drainage basin (Q166620) (note: this should be moved to the property statements) | ||||||||||||
| Usage notes | Use the most specific item available. Items for smaller basins should be used instead of items for bigger basins that include the smaller ones. If a river flows directly into the open sea or pretty much, do not create an item for its basin, use the item for the basin of the ocean or sea. You should create an item for a basin only when there are ~ 25+ other items that can be linked to it. | ||||||||||||

Watercourses in a basin that includes the basin of the watercourses they flow into. Thierry Caro (talk) 00:19, 31 October 2019 (UTC)
Confusing description edit
@Thierry Caro, ChristianKl, ArthurPSmith, Fralambert, ديفيد عادل وهبة خليل 2: The "description" contains unnecessarily an overly comprehensive definition of a generally known term (of the related item), but does not contain a sufficiently unambiguous definition of the property. The property label can evoke two different meanings:
- belongs (falls) into drainage basin (applicable to any geographical feature, but not very useful for other than watercourses and bodies of water)
- own drainage basin (applicable to bodies of water: watercourses, lakes, seas etc.)
The label, the description and the logic of Wikidata structure can evoke rather the second meaning, while the usage examples correspond to the first meaning. For the first meaning, the property is mostly redundant, because for watercourses, parent basins follow from the property mouth of the watercourse (P403). Moreover, it is not clear which level of superior basins to indicate from their hierarchic structure. A property for the second meaning is more needed and useful. I suggest splitting this property into two different properties and editing the label and description to be concise and unambiguous. --ŠJů (talk) 03:03, 9 December 2022 (UTC)
- Hello. As a general rule, use the most specific basin every time. I don't think I see the need for that second property. Thierry Caro (talk) 12:22, 9 December 2022 (UTC)
- @Thierry Caro: The most specific basin is always the own basin. That's the second meaning. The basin of the parent watercourse is a redundant property because it is given by mouth of the watercourse (P403). Properties should primarily express direct relationships between items, not indirect ones. A basin item should be linked with their river, lake or sea, and a river item should be linked primarily with their own basin. --ŠJů (talk) 04:40, 10 December 2022 (UTC)
