It seems like you're putting the text out under CC-4.0-BY-SA [1] (Attribution, Share-Alike), which is great (the updated version of the same copyright for Wikipedia content). However, you're also collecting a TON of structured and relational data, which seems to be the value generated by your editor. Are you planning on keeping that locked up?
