[media-types] Re: [IANA #1421602] application/vnd.nu baltec.nudoku-game registration request

Hi Amanda,

Sorry for the delay on this one.

I have some non blocking comments for the requestor (see below), but in 
general this is reasonable to register.

It contains neither executable code nor private information, but just the data required to reproduce a game state. The files should be about 3-4 kB in size. Depending on the operating system, existing security vulnerabilities of the devices' json decoder and file i/o libraries may apply.

It may be opened in a text editor and read, but is primarily designed to exchange game configurations between users of the nudoku app.

Is the file format pure JSON or does it include some header? If the 
former, I am not sure this is true.

It looks like this file extension is already used by one of Adobe image 
formats. I suggest a different file extension is to be used.
