Difference to mouth of the watercourse (P403)[edit]

Can someone explain me in which sense this property differs from mouth of the watercourse (P403)? --Pasleim (talk) 19:28, 29 October 2013 (UTC)

@Pasleim:: it is the opposite ! :). --Zolo (talk) 07:15, 22 February 2014 (UTC)

Inverse[edit]

There should probably be a "Tributary of" property also. (A river would be a tributary of only 1 other water body, except in very exceptional circumstances.) --Closeapple (talk) 08:31, 7 December 2013 (UTC)

Considering this and the previous section, I've proposed aliases at Property talk:P403#Relationship to tributary, to add "tributary of", "flows into", and "water mouth is on" to mouth of the watercourse (P403). Anyone with objections can comment there. --Closeapple (talk) 23:19, 11 July 2014 (UTC)

lake inflows (P200)[edit]

What the difference with this property? Infovarius (talk) 16:05, 28 August 2015 (UTC)

tributary (P974) is for rivers flowing into another river, lake inflows (P200) is for rivers flowing into a lake or sea. --Pasleim (talk) 21:34, 30 August 2015 (UTC)

Use for veins in anatomy[edit]

OBO defines tributary_of as:

 "X tributary_of y if and
 only if x a channel for the flow of a substance into y, where y
 is larger than x. If x and y are hydrographic features, then y is
 the main stem of a river, or a lake or bay, but not the sea or
 ocean. If x and y are anatomical, then y is a vein."

Can this property be defined that way so that it's also useable for veins? Anandhisuresh (talk) 17:16, 28 February 2018 (UTC)anandhisuresh Tobias1984

I don't see the benefits of mixing the two. Same English word, but they don't really interconnect.

P4614 (drainage basin) constraint[edit]

I'm deleting this constraint, since it doesn't seem very relevant: you shouldn't need to know about a river's drainage basin (and create an item for it) before you can name its mouth or tributary. It has 10859 violations. Ghouston (talk) 06:10, 7 November 2018 (UTC)
