Hi Jo - sorry I didn't get a chance to respond to this sooner. We've 
been busy opening up more data [1]

Thanks for pointing this out. What we actually mean by "data" in this 
case is the metadata. We don't mean to imply that you've modified the 
underlying data license.

We've been actively working with various groups and Lawyers on how CC 
applies to data. Obviously there has been a lot of work in ODbL, but 
we're still missing the "menu" of available licenses. Currently all 
licenses are unique unless they're using PD/CC0.

We could simply add a large text area for "copy & paste license here", 
but we're hoping for a more user-friendly option that then allows users 
to search across datasets, like one can do in Flickr, for "all 
redistributable" or whatever.

If there are suggestions for how to achieve this without making the 
metadata process daunting - definitely open to ideas. We want to help 
the global community make open data beneficial and easy to use. 
Consumption and demand drive more open-ness. See Nat Torkington's recent 
musings on the retrospective of New Zealand's open data initiative. [2]

Good question - we've had the GADM data for quite awhile now and I 
believe permission was obtained. But I'll get clarity - and a good 
reason for some mechanism of specifying data openness in the metada  :)
