[od-discuss] Exploring licence compatibility

[Kent Mewhort]

Nice work! CIPPIC's also been doing some work in this area. Our 
articling student just finished a Compatibility Report on open data 
licenses. It's not quite ready for release, but we should definitely 
compare notes when it's done.

I ran the same licenses in your one-way compatibility chart through the 
CLIPol algorithms (matrix screenshot at 
http://clipol.org/clipol_dodds_compare.png). We're pretty darn close to 
each other's results, but there are a couple of differences:

   - CC-BY -> ODC-BY, ODC-ODbL and OGL2: I have these as incompatible 
due to CC-BY prohibiting TPMs. This is for CC-BY-3.0 though; CC-BY-4.0 
won't have this restriction and will be compatible.
   - OGL2 -> CC-BY-ND and CC-BY-NC-ND: I actually have these as 
compatible. What were the reasons you found them not?
