Subject Re: [DISCUSS] What should we do with cTAKES resources?
Date Mon, 05 Nov 2012 12:40:37 GMT
In my opinion we should release what we can from here at Apache
and only the resources which have an incompatible license need to
be handled differently, e.g. external site.

Models which are trained on private clinical data can be released as 
long as the
original creator decides to license them under AL 2.0. If that is done 
by a committer
it should be fine to just check them in or put them on the website.

The wikipedia license is compatible and an index of it as well, but we 
probably need
to have attributio for it in a NOTICE file, and maybe include the 
license in the LICENSE file.
