Huh, I edited that region recently.<br/>
<br/>
When importing via JOSM the addr:flats don't stand out that much
because it just renders the housenumbers. I usually don't even
notice until uploading. I think I'll be converting the obviously old
imported addr:flats' in Leuven to "note=possible addr:flats: ... "
with a FIXME.<br/>

<div>Sander,</div>
<div>I absolutely agree with this! <br/>
</div>
<div>However, as much as I am a fan of CRAB, I don't really
trust the subaddresses. They caused me way too many headaches
when I still worked in the city of Antwerp. Anecdotally, I've
surveyed one building for subaddresses near me, and there was
zero correlation between what was on the post boxes and what
was in CRAB. So while I agree the info is useful, I wouldn't
recommend importing it. And a cursory glance at the data shows
that almost all addr:flats we have, are in fact imported. See
<a href="http://overpass-turbo.eu/s/V7K" moz-do-not-send="true">http://overpass-turbo.eu/s/V7K</a> -
the vast majority here has the tell-tale source:geometry:date
tag from the GRB import; the ones I checked that haven't seem
to be CRAB-imports.</div>

<div>You can do things with that data besides rendering or

<div>If the data is more or less complete, you can process
it to get the number of addresses on a street or in an
area (for example, if you want to distribute a folder to
the entire street).</div>
<div>Or as a postal service, you can check if that address
needs a flat number, and suggest a list of flats to the
users.</div>

<div>Like that, I always considered the values worth to be
in OSM, even if it's all on the same door/building. Though
it's obviously a lot less important than housenumbers.</div>

it's a bit like adding entrance=yes on the building to say
that a<br/>
building has an entrance somewhere, you don't add any real
information.<br/>
<br/>
so at this place, I would not have added any addr:flats
which would have<br/>
solved the problem of rendering :) I will only use it in
the case of a<br/>
building with more than one entrance, and so addr:flats on
the entrance<br/>
does not disturb the display of addr:housenumber for the
whole building.<br/>
