[OSM-legal-talk] Merano Italy will be donating their data! CC-by-SA and donated data?

[Mikel Maron]

To coincide with the South Tyrol Free Software Conference and OSGeo Code sprint in Merano, Italy next month

http://www.sfscon.it/2007/
http://wiki.osgeo.org/index.php/European_GIS_Code_Sprint#The_OSM_datacollection_event

the city of Merano has agreed to release all their municipal GIS data!

They would like to release it under CC-by-SA. My question to legal-talk is, what are the practical ramifications for attribution?

Of course this is an open question. But we do have one precedent, the AND data. According to the wiki, 
that is licensed as CC-by-SA. And in practical terms, that has meant a statement in the wiki, and all data has been imported
under the user 'AND'. To me, that seems sufficient.

Any thoughts?
