<p>Hi all,</p>
<p>I've just joined the talk-ca list, so please accept my apologies
for not addressing this list earlier. I'm happy to take this
thread off the imports list for now and onto talk-ca until things
are ready to begin again. The next person to reply can please feel
free to remove that email if they agree. <br>
</p>
<p>I've just made a note on the draft import plan wiki page noting
that the import has been stopped:<br>
</p>
<p><a class="gmail-m_-676608083061393321gmail-m_-980834973340345641gmail-m_2465862792154107082moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/WikiProject_Canada/Canada_Stats_Canada_Building_Outlines_Import/Plan" target="_blank">https://wiki.openstreetmap.org/wiki/WikiProject_Canada/Canada_Stats_Canada_Building_Outlines_Import/Plan</a></p>
<p>I would really appreciate it if the person with admin access to
the tasking manager projects could please take those offline for
the moment, or perhaps place them in a validation-only mode if
that's possible. <br>
</p>
<p>Like I said in my last email, which perhaps didn't make it to the
talk-ca list
(<a class="gmail-m_-676608083061393321gmail-m_-980834973340345641gmail-m_2465862792154107082moz-txt-link-freetext" href="https://lists.openstreetmap.org/pipermail/imports/2019-January/005886.html" target="_blank">https://lists.openstreetmap.org/pipermail/imports/2019-January/005886.html</a>)
I'm now proposing that we leave the data that has already been
imported and enter a phase of thorough validation on that data. <br>
</p>
<p>My plan, over the next several days, is to do a general survey of
the quality of the data that has been imported so far and make a
list of systematic issues I see that should be addressed before we
can consider moving forward again. I'll add those comments to the
conversation in talk-ca and on the wiki page (link above), as I
feel is appropriate. As I said before, I'm of the mind that this
import did not get adequate review or approval and did not follow
all the import guidelines. I think therefore we need to take
stock, cross the t's, dot the i's, and move this thing back toward
where it needs to be. Step one is a thoroughly documented wiki
page outlining the proposal and responding to everything required
in the import guidelines. <br>
<a class="gmail-m_-676608083061393321gmail-m_-980834973340345641gmail-m_2465862792154107082moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Import/Guidelines" target="_blank">https://wiki.openstreetmap.org/wiki/Import/Guidelines</a><br>
</p>
<p>I know there are people excited about this import, and people who
are eager to get back to work bringing buildings in, but I think
everyone will be happier in the end if we take the time to do this
right. We don't need to stop forever - we just need to stop until
we get things right. I sincerely respect the good intentions of
everyone involved in this and I hope we can all work together to
make OSM a map known for it's coverage AND it's quality. <br>
</p>
<p>Best,<br>
