> The IETF is currently checking the specification of Zstandard compression and

> [https://tools.ietf.org/id/draft-kucherawy-dispatch-zstd-01.html|https://tools.ietf.org/id/draft-kucherawy-dispatch-zstd-01.html]
> As soon as the MediaType application/zstd is set as standard the Media Type 
> shall be implemented.
> Possible mime-detection for tika-mimetypes.xml (second comment has to be 
> changed when the standard is final):
