Everyone does not participate in all the OSM news sources. Thus people
are surprised when presented with stuff they had no idea of.
Of course, they never will participate in everything. But we as a
project don't have any defined channels where one could expect to catch
all the news about the most important changes (as the project see them),
let alone any broader efforts to reach the OSM data and services users.
It was just what one man was thinking what would be suitable and enough
to be widely heard.
There are also some examples of well thought and even accepted tagging
schemes which are not in a wider use, like:
- highway:area (4 years before it really took off now!)
I don't use it. And so on . Mappers won't use stuff that they don't
see a need for.
It's completely irrelevant if just one of us use it or not: in my ~8
years in the project I have probably never tagged any orchard, vineyard
or a lake, but it has nothing to do with their technical merits or a
need for them.
The area:highway (this is the right name BTW =} ) is very interesting in
this regard and I know it from the close perspective, so let me describe
this case. It was created 4 years ago by a man, who not only had the
clear idea, but also made big effort to document it on the Wiki with
images explaining details (
https://wiki.openstreetmap.org/wiki/Proposed_features/Street_area ). It
took a lot of time to get real support. 2 weeks ago it was about 10-12k
uses: not that much, but clearly more than competing proposition
landuse=highway (2.4k). However nobody would notice it if the creator
was not still active. He let us know about that and even more: he
managed to get support from a programmer who made a rendering layer for
the whole country ( http://osmapa.pl/w/area/ ).
That was the tipping point. The people started mapping it massively,
another guy made a JOSM template to made it easier and less error prone,
than the creator contacted also German and Ukrainian mappers, which also
got their a:h layers on the same server ( http://osmapa.pl/w/areade/ and
http://osmapa.pl/w/areaua/ respectively). The specification was extended
and revised in many ways in the process. And now (just a dozen days
later) area:highway has about 25k uses - more than double than it
achieved in a few years!
The lessons I've learned from this example are multiple:
1. It's not enough to make good, detailed proposition anymore - you
never know the people aren't using it because they're just not
interested or maybe they lack some tools.
2. Wider rendering support is important factor of implementing tagging
scheme (there was some rendering before, but it was very local).
3. You have to be stubborn, active, focused, patient and has good
communication skills to be effective in implementing something new these
days. There are not too much people being all that - and this was just
introducing new, harmless scheme, not revising established ones, which
could be much harder, I think.
4. Current practice of crafting tags by just discussing things on the
list is rather ineffective. Close (agile) cooperation in working group
with creator/promoter/renderer/editor involved works much better,
because not only implementing is faster, but also the definition is
corrected and extended basing on the real tagging and rendering
experience (so a double win - with quantity and quality).
So what makes the changes from amenity to shop attractive?
Mappers -A more logical grouping that is easier to remember.ut
Editors -A more logical grouping. SO not much here.
Renders -A more logical grouping that means rendering is easier.? Same
colours for all shops?
Corrections like this make the whole system more clear and usable. It
also means crafting new tags is easier, because you just follow the
logic of the system, not try to guess the rules and spot the
inconsistencies.
Slow changes are much better than sudden ones. Give people time to
adapt.
These are not contradictory claims. You can give people time to prepare
and then one day make the switch, which would be more effective and
reducing many other problems - or simply allowing the change to be real
(see for example: https://en.wikipedia.org/wiki/Dagen_H#Results ).
