[pombredanne]

Thanks... I made a few comments ... (and I know this is still a draft.)

[gaupeng]

@pombredanne I have updated OSI License Keys for the Licenses that have them. Is this fine?

[pombredanne]

This is looking quite good... I have just a few nit pickings for your review

[pombredanne]

This is not used. Also we like to sort the imports

[gaupeng]

I'll do the sorting, however, I do use urllib.request to use the OSI APIs to derive the license keys. Also, when I remove the licensedcode.index import, I get a NameError: name 'licensedcode' is not defined error. Should I leave this in?

[pombredanne]

may be some checking by hand of all the "keys" seen in https://www.google.com/search?q=site:https://opensource.org/licenses may help too?

[pombredanne]

Looking all good tome!
Thank you ++
