In 'new formalism' would not be different for user of web interface:

# or, possibly application/zip:application/n3 (for those being really precise)
format: zip:n3

# optional as this is default kind
kind: file

# you wouldn't provide the mimetype probably (we'd 'guess' it for you)
[mimetype: application/zip]

# i'm wondering whether we should have mimetype inner
[mimetype-inner]: application/n3

Yes, basically though there would also be:
