[OSM-talk-be] generalized survey and consequences

[Glenn Plas]

I found no "survey:" key, if I look for 
http://wiki.openstreetmap.org/wiki/survey, it falls back on key:source 
http://wiki.openstreetmap.org/wiki/Survey#Annotation (which is a non 
existing label).

It would help 'knowing' how long ago it has been made and explain why 
certain things turned incomplete/wrong overtime.

I haven't found a way to do it.   You could create a union when you know 
what keys to search for (but that kinda misses your point I assume).
