Change license to one that is more applicable

[hlapp]

The MIT license is for software and not a good fit for different creative works. I'd suggest we either use CC-BY or CC-Zero. However, note that the W3C seems to be using their own document license, which in spirit is more like CC-BY-ND.

Good point! My instinct would be to go for CC-BY. Is there a good reason to prohibit derivative works? Here's what Creative Commons says about adaptations -- I don't think there's anything in there that we'd like to prohibit.

I agree. I think it'd be best to check against TDWG expectations, conventions, or customs, in particular if we eventually will pursue ratification by TDWG.
