[OSM-talk-be] URBis, Open!

[eMerzh]

Hi ,
Thanks for you researches Jo... i'm currently reading the user guide given
upper, and it may helps you to understand what's what :p

yesterday Cquest from osm-fr gave me his extract of addresses so it must be
possible some way ... (see here
http://my.bmaron.net/public.php?service=files&t=7264154f5a483352ebe0846fdeeeabbb)

For the integration ... as it seems that the datas are far better than
what's already in osm ( a lot of buildings where drawn by hand on top of
bing ....)
and addresses are far from complete ...
my opinion is that we may try to first "integrate" buildings then address
(address seems to be easier i think it's better if we could link them to
the building).
Another place where an import will be hard but we can still do smth is
roads names.

Then of course there is a lot of other things we can start thinking ...
like pharmacy , ...

Btw,
how do we manage the attribution ? a text in the wiki pointing to URBIS? a
source=* on every object ? or a source=* on the changeset?
