4. Redesigning some key tagging schemes
I think that will be one of the hardest think to change, but while tag
crafting is mostly a grassroot process, we need to rethink some of
them in a more systematic way.
For example amenity=school should be really landuse=school (if not
used just for the building), landcover namespace should arise (so on
the landuse=park we can see green space only when there's a grass
actually, not on the whole this area), maybe some nature/man_made
tagging should be replaced by terrain namespace... That's not
important what exactly should be (re)designed from top to bottom this
time, but once you have the needed level of expertise, you can make
new implementation better instead of just patching the original one.
We also have a lot detailed objects which are not always clearly
defined and we should try more "cascading" approach, like
"amenity=fast_food" => "amenity=food+amenity_food_type=fast_food" (or
something alike). That way we can have "Here is food!" label without
forcing mapper to distinguish if he's not really sure.
I expect there will be strong reaction against using "top-down
committee" methodology, but some well-known problems with our ontology
architecture will never go away if we try to change it tag-for-tag. Of
course that is true only for this class of problems - most new schemes
will still be best when created ad hoc and then used by more and more
mappers.
There needs to be a guide as to the tagging scheme/system/philosophy.
You use the example of fast food... to me that is a shop .. so rather
than amenity= it should be shop= ... thus 'a place that sells a product'
should precede the selection of 'amenity=' ?
I'll add the problem of waste .. I believe there needs to be a top level
tag of waste= ... at the same level as amenity= etc ..
In the long term there needs to be a good understanding of what
scheme/system/philosophy is to be used, and it needs to be Documented
with a capital D. If that is done by a committe or a loose group the
doucumentation still needs to be done .. and done before some redefining
tags if an over all scheme/system/philosophy is too succeed.
