you for your comments Greg! We've been drafting a longer response that
we wanted to share, and this seems like a good moment to jump in and do
so. Firstly, thank you to everyone for your engaging feedback! We’ve
learned a huge amount about the weaknesses and strengths of our
proposal.</span></p><br><p dir="ltr" style="line-height:1.656;margin-top:0pt;margin-bottom:0pt"><span style="font-size:13.3333px;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline">We
think it would be helpful to talk about our motivations in posting this
import (and the schema suggestion), to give our points some context. We
have started this project with the goal of making sidewalks in OSM more
useful for the greater community, particularly people with limited
mobility. With its principles of openness and inclusion, OSM is uniquely
positioned to adopt a data model that can make a big difference for
people who use wheelchairs, crutches, or otherwise have difficulties
walking, while also improving the data in the map. While we hope this
will have a global impact, we are starting with a local import, are
engaging the local OSM community, and are setting up stakeholder
relationships for the maintenance of the data.</span></p><br><p dir="ltr" style="line-height:1.656;margin-top:0pt;margin-bottom:0pt"><span style="font-size:13.3333px;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline">We
would like to distinguish, as best we can, our schema proposal (on the
OSM wiki) from the import. The data to be imported does not have enough
metadata to make use of all the tags we are suggesting, and primarily
comes down to annotating the basic feature-level descriptions of
sidewalks, crossings, and curb ramps. We may be able to add one or two
more pieces of information (like width, surface, and kerb tags), but we
consider this to be an opportunity more than a requirement. In all
cases, the tags we would use are not new or in violation of OSM
standards, in our understanding - they are all in heavy use in many
locations, with wiki entries, even though tagging streets with sidewalk
information is popular in other locales.</span></p><br><p dir="ltr" style="line-height:1.656;margin-top:0pt;margin-bottom:0pt"><span style="font-size:13.3333px;font-family:Arial;color:rgb(0,0,0);background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline">To

terms of putting the burden on existing volunteers, we actually think
that this could be used as a strategy to get more people into mapping.
We were lucky enough to speak to a lot of OSM meetup organizers at
SOTMUS and something which came back consistently is: they need
interesting projects to get people to turn out for mapathon events, and
projects with a social angle are really effective at this. Obviously
this isn’t a new idea, and we can point to the work done by the HOT team
as a really positive example of this. Additionally, we have found that a
more human-centric approach draws people in. We are interested,

</span>I look at the recent turn lane work that MapBox is performing. They<br>
have done a wonderful job of finding issues and developing use cases<br>
for the rest of the community. Far worse than the alleged GIGO of<br>
this import is the NINO. Without out MapBox's activity we would not<br>
have a well developed definition of turn lanes. Without sideway data<br>
mapped and worked on, we'll get no where with these kinds-of<br>
discussions. I look forward to see what the Washington community will<br>
find. I am still working out details of my sidewalk edits. I'd like<br>
to build on the Washington data that will be developed.<br>
