Does a building get a new number if it is is built on a plot with am<br>
existing building? Or do the two neighbouring buildings (the old and the<br>
newly built) share a stand number?<br>
<br>
Are stand numbers only unique within a city or a borough? There is<br>
something similar in Germany (and other European countries as well). A<br>
lot of smaller villages do not have street names. When a building is<br>
built, the local authorities assign the next free number. Only buildings<br>
in the centre of these villages seem to have ordered number because they<br>
got their numbers en bloc when addresses were introduced. These numbers<br>
are only unique within the village. The name of the village is used as<br>
street name in postal addresses in these cases and addr:place used<br>
instead of addr:street.<br>
<br>
It looks to me that addr:housenumber=<stand number> + addr:place=<name<br>
of city/borough> is a valid tagging in your case.<br>

It looks easier but it bears the risk that you mess up data by<br>
automatically editing it. Don't underestimate the conflation of existing<br>
OSM data with your data.<br>
<br>
In addition, an import should not replace existing geometries in OSM by<br>
new objects just because it is "easier". Instead, the existing<br>
geometries should be modified to preserve their history.<br>

<br>
There are no layers in OSM in usual GIS sense.<br>
<br>
Did you get familiar with OSM in the past by doing some mapping in OSM<br>
in the area where you live and/or which you know well, e.g. adding<br>
points of interest or enhancing the map with local knowledge? It helps<br>
one to understand how OSM works, how the data looks like, how good the<br>
data is and what to do if things go wrong.<br>
<br>
I think that people on this list can give concrete advice if you write<br>
down your plan on a wiki page as others imports do. You will find<br>
examples in the archives of this mailing list.<br>
