Hi! Thanks for your contribution, but you cannot edit the db.json file, as that is auto-generated only. If you can update your pull request according to the instructions at https://github.com/jshttp/mime-db#contributing that would be awesome :)

@dougwilson done 👍

Thank you! Since they are not part of the IANA, do you have any links to where they are specified?

[ronanww]

@dougwilson I added the sources to the json file, check them out

[dougwilson]

Thanks! I don't see it mention those file extension anywhere, though. Can you add the links to where the file extension associations are as well?
