Formatter URL and values

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 types

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 constraint

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)

removed required statement of filename extension (Q186157)

I had a look at /usr and at my Dockerfiles. I noticed that this constraint made little sense. -- Dr.üsenfieber (talk) 08:15, 11 April 2020 (UTC)

Subject type constraint: not to be used on data formats

media type (P1163) should not be used on content format (Q5165081) (generally referred to as "codecs"), only on containers. That's why I replaced the authorized subject data format (Q494823), too broad (one of its subclasses is content format (Q5165081)) by file format (Q235557). --Dipsode87 (talk) 12:25, 7 August 2023 (UTC)

I think content format (Q5165081) is acceptable for media type (P1163). It seems that the RFC 4855 and RFC 4856 uses media types for audio coding format (Q758871) and video compression format (Q7927899) (both are subclass of content format (Q5165081)). --Wdpp (talk) 15:44, 8 October 2023 (UTC)
