</div>I'd like to avoid discussing licenses too much since it's a hot topic,<br>
and not in the good way...<br>
<br>
But if you've accepted the CT, the CT handles the licence transition<br>
as far as OSM is concerned. But your organisation must be comfortable<br>
handing this data to OSM and letting it re license it.<br>
<br>
Let me put it to you another way...<br>
<br>
Once you accept the CT and contribute the data to OSM, the data<br>
belongs to the OSM Foundation, and the foundation may re license it.<br>
There are very good reasons for this, but as you might imagine, this<br>
can be somewhat controversial.<br>

<br>
</div>Nothing dumb about this; it's a bit complex.<br>
<br>
The short answer is, as long as you've accepted the CT on behalf of<br>
your organisation and they're okay, you don't have to worry about<br>
licenses again.<br>

<br>
</div>You don't need to change your database to fit our API.<br>
<br>
Let's imagine a fictional database full of historical fountains.<br>
<br>
The table might be "fountains" and there might be a single row called "latlong"<br>
<br>
OSM doesn't care about how the data looks internally, it only cares<br>
about how the data looks when it enters the system, that is a fountain<br>
from your system would need to come in like:<br>
<br>
<node id="-1" lon="..." lat="..." version="1"><br>
<tag k="amenity" v="fountain" /><br>
</node><br>
<br>
Using our XML schema as per the API documents.<br>
<br>
This example is a little simplified, but you probably get the point,<br>
which is that OSM only cares about the data representation as it<br>
enters OSM, not how it's represented inside your own system.<br>
<div class="im"><br>

<br>
</div>In several jobs I've been at, I've had to do data mapping from one<br>
system to another. Maybe one customer has one stream format they<br>
prefer data in, and another is different.<br>
<br>
OSM has its own format, and it would then be your job to map the<br>
fields in your database to ours.<br>
<br>
So for example, "place_name" might become "name", and so on.<br>

</div>They should be roughly the same. Can you give me a specific example of<br>
a difference?<br>
<div class="im"><br>

<br>
</div>They generally don't. If they do, use the local one.<br>

<br>
</div>dev06 is meant for experimentation of software and you are encouraged<br>
to use it as such. The data in it is throwaway, so be aware that what<br>
you see won't look like normal OSM data.<br>
<div class="im"><br>

<br>
</div>That's an excellent question. I've been suggesting this for a long<br>
time. My suggestion is join the import list, write up a wiki page on<br>
it, share it, share the osm, wait for feedback. If you don't get any,<br>
go for it. If you do get feedback, try to address it.<br>
<br>
This process may seem slow, but as someone who has personally caused<br>
import pain, and spent a long time cleaning it up, I can tell you it's<br>
well worth it.<br>
