[OSM-legal-talk] License clarification question

[Sebastian Kurfürst]

Hello everybody,

I am working for a small startup company which wants to provide  
geographical information for tourism areas. We intend to produce an  
online map-widget like you have at your website, and want to add a  
custom overlay of touristically relevant POIs (Hotels, Guest houses,  
Restaurants, ...). If you click onto one of these overlay icons, there  
will be a popup with additional information, photos, prices, opening  
hours, ...
The POI information is stored separately (in a separate Database  
table) from the OSM-based way / polygon data.

We are currently evaluating the use of OpenStreetMap data as a basis  
(for roads, hiking trails, ...)

Now my questions:
- Do I get it right that the current license is CC-by-SA 2.0? And you  
want to switch to the new Open Data License? Is there any timeframe  
when this switch will be done?

- As I understood it, we'll have to publish all of our modifications /  
additions on the underlying OpenStreetmap Data, f.e. as JOSM XML file.  
We are happy that this information can flow back to the OpenStreetMap  
project :-)
Is this correct as I see it?

- However, the POI information (where the POI is located, and the  
additional meta-data which is displayed in some kind of "popup  
bubble") does not have to be published under the same CC-by-SA license  
- is this correct?
If the meta-data needs to be published under the CC-by-SA license as  
well, that would be a major issue for our company - that's why some  
clarifications would be really nice.

Thanks a lot for your help,
you OpenStreetMap guys rock,
Sebastian
