Sorry, I didn't had much time to deal with that...
Yes in my had I have a plan for all those information, the problem is it is in my head.

For a quick draft of what I think. 

We should probably namespace stuff with a subkey, potentially a `_draft` key while we are working on it. 

Second, you will have multiple authors, so Authors will probably be a list. 

each author shoud IMHO have multiple field, from the top of my head : 

  - first name
  - last name
  - mail
  - github account
  - institution
  - contat author [bool]
  - main author [bool]

... and all kind of things like that, I think you see what I mean.
And this should probably be editable with a notebook (extension ?) to the UI, and should also be reflected in the long term in nbconvert with link to profile/avatar...usw.
