Formatter URL and valuesEdit

I tried to set a formatter URL. It seems to work for some, but not for others. Is just the IANA site is more complicated or incomplete, or do we include types that are not registered? --- Jura 08:38, 20 October 2015 (UTC)

Unofficial MIME typesEdit

chemical MIMEs are not official MIME types [1] but [2] claims they are widely used. Should we accepet them? --Pasleim (talk) 12:45, 28 January 2017 (UTC)

Pasleim As far as I see, general practice mentions unofficial MIME types in file format items. They should be easy to distinguish from official ones thanks to the "x|X" subtype prefix and because they lack a stated in (P248) qualifier specifying an RFC. --Dipsode87 (talk) 11:08, 18 December 2019 (UTC)

Distinct values constraintEdit

I removed the distinct values constraint since many file formats and file format versions can share the same MIME type. --Dipsode87 (talk) 09:12, 5 October 2018 (UTC)
