[OSM-talk] possibly redundant proposals

[Robin Paulson]

there are some proposals that have been under industrial (a
non-existent top-level tag) now for several months

http://wiki.openstreetmap.org/index.php/Proposed_features#Proposed_Features_-_Industrial

they are probably useful, but there is no detail for any of them, and
i'm not sure what 'bore', 'shaft' (mineshaft? which is a proposal) and
'line' (pipeline?, a feature already) are, or where we would use
'vent' (on the side/top of a building?)

could whoever put the proposals up, or someone who has more knowledge
of industrial plants, add some detail please?
