Nick Burch commented on TIKA-3144:
----------------------------------
Generally you need to use the {{x-}} prefix on the subtype to mark it as
unofficial (not IANA approved), though rules are a bit different in the {{vnd}}
subtype space. No need to prefix the type.
However, those rules tend to assume that the people who invented the format
will want to assign the mimetype themselves, and then submit it for approval,
and don't work so well when the folks behind it can't/won't take charge of the
mimetype process for their format... See

> Detecting hprof memory dump files exported from Android Studio
> --------------------------------------------------------------
>
> Key: TIKA-3144
> URL: https://issues.apache.org/jira/browse/TIKA-3144
> Project: Tika
> Issue Type: New Feature
> Components: detector, parser
> Reporter: Parth
> Priority: Major
> Labels: android-studio, hprof, memory-dump
>
> I was trying to detect a hprof file by downloading and passing it as input
> stream to tika. But the MIME type is being detected as
> `application/octantstream`. Can a more granular support for detecting if a
> file is of type hprof be added?
> Hprof files are Java memory dump files and you can read more about it here:
> https://dzone.com/articles/memory-analysis-how-to-obtain-java-heat-dump
> I had found this parser for hprof in Java if it helps:
