[Tagging] tagging for decaying features

[Warin]

Hi


At present decaying features look to have the following progression for me;


disused:  wiki documented - where it can be readily put back into service

abandoned:wiki documented   - where a good deal of work would be needed 
to put back into service.

ruin: no wiki documented - where a totally new feature build would be 
cheaper than a rebuild.

raised: no wiki documented - where most of the feature has been removed, 
so little remains that it is hard to distinguish.

  and then finally gone: or archaeology: where it would take archaeology 
to find traces of it! I think most would see this as not belonging to 
OSM but rather OHM.


I note that;

ruin is used with buildings .. but as the sub tag ruin=yes.


raised: is in use.

https://wiki.openstreetmap.org/wiki/Demolished_Railway suggest using 
railway=razed (amongst other things) ..

yet that can not be used with other features such as a railway station!


Presently I am using gone: as a path to placing some things on OHM.

Once I am happy that they have gone across to OHM I should then delete 
them from OSM.

Questions (to get some thoughts from others)


Should the following be adopted and if so with what definitions?


1) ruin: - where a totally new feature build would be cheaper than a 
rebuild.


2) raised: - where most of the feature has been removed, so little 
remains that it is hard to distinguish.
