brain death (Q223867), cell death (Q2383867) --Fractaler (talk) 07:39, 12 December 2016 (UTC)[reply]

@Fractaler:
Common definition of death is about living organisms or creatures as whole, so subclass of is not exactly appropriate here
Brain can be dead but other organs can be removed and transplanted.
But they imply Q23956356  View with Reasonator View with SQID event. d1g (talk) 17:34, 15 September 2017 (UTC)[reply]
@Fractaler: so, death (Q22299430) P279 Q4 is not the most precise claim - if you meant this d1g (talk) 17:59, 15 September 2017 (UTC)[reply]

Description

[edit]

permanent cessation of vital functions of a cell? Or body? Or brain? Or population? Or biosphere? --Fractaler (talk) 18:31, 15 September 2017 (UTC)[reply]

@Fractaler: it should be "body" first indeed: of a person or organism
If one cell is dead (Q2383867) it doesn't follow that organism is dead (maybe Q4): regeneration and regrowth is present in many organisms.
we should create specific items about related events and stances. d1g (talk) 18:47, 15 September 2017 (UTC)[reply]
cell is a 1-cell organism. There are also superorganism. --Fractaler (talk) 18:53, 15 September 2017 (UTC)[reply]
"cell is a 1-cell organism"
Not about current claims at cell (Q7868)
Q7868 is very indirectly related to cadaver (Q48422) or body (Q170494); It is easier to claim in opposite direction d1g (talk) 19:02, 15 September 2017 (UTC)[reply]
Ideally we should have a separate subclass of body (Q170494) (or maybe organism (Q7239)) per every taxa
Then it would be easier to claim their parts as "nervous system" or just "cells" d1g (talk) 19:19, 15 September 2017 (UTC)[reply]
unicellular organism (Q36468) - organism --Fractaler (talk) 19:22, 15 September 2017 (UTC)[reply]
Actually a good note, in this case death of one cell = death of body
This is another example why we shouldn't state P279 in any direction between death of one cell ? death of body.
This P279 claim heavily depends on taxa. d1g (talk) 00:39, 16 September 2017 (UTC)[reply]

Confusion about properties

[edit]

properties for this type (P1963) on this item indicates which properties can be used on instances (or subclasses). This would be location/point in time, not the properties in use on the items about people. Hope this clarifies it.
