[Tagging] difference between cycletrack and cycleway

[SomeoneElse]

I'm not sure that I understand your problem.  Currently when people see 
something they decide what to tag it, based on what other people have 
used in the past and/or what's documented on the wiki - some people are 
seeing things for which they think "foo=bar" is appropriate.  Often the 
choice of tag is very subjective and far from straightforward.  If you 
haven't been to the place that they're mapping, how can you say that 
they're wrong and you're right?

Are you trying to create a schema into which all of the "foos" of the 
world fit, and impose that on mappers?  If so, OSM may not be the 
project for that - it's strength is very much that mappers can make 
things up as they go along, and tag usage can evolve beyond what a bunch 
of people at the start of the project thought was needed.

If you're coming at this from a data usage perspective, then regardless 
of how people map going forward there are an awful lot of 
"cycleway=track" out there and you're going to have to either (a) deal 
with them or (b) do a large amount of worldwide surveying and remapping.
