[Docutils-develop] [docutils:bugs] #516 FAQ says MIME type for rst is text/x-rst but its source page is served as text/prs.fallenstein.rst

[Günter M. <mi...@us...>]

Thank you for the information.
According to the IANA entry, Benja Fallenstein  registered the "rst" MIME type because:
> The registrant just happened to have need of a registered media type for it.
--- https://www.iana.org/assignments/media-types/text/prs.fallenstein.rst

So the actual error is not the quoted part of the FAQ answer, but
> ... there is no registered MIME type for reStructuredText, ....

It seems that with the switch of the source file extending from ".txt" to ".rst" in August 2024 some applications started to use the registered MIME type when serving or analysing the source files.

The Docutils FAQ says in section 2.24 https://docutils.sourceforge.io/FAQ.html#what-s-the-official-mime-type-for-restructuredtext-data:

> [...] the "official unofficial" standard MIME type is "text/x-rst".

However, when following the "View document source" at the bottom of the page, I get a different MIME type:
~~~
$ curl -I https://docutils.sourceforge.io/FAQ.rst
HTTP/2 200 
date: Mon, 15 Dec 2025 07:20:49 GMT
content-type: text/prs.fallenstein.rst
[...]
~~~
Clearly, this is not what the FAQ says.
