[jira] [Created] (TIKA-4058) Add file extension .rmd160 to tika-mimetypes.xml

Gregory Lepore created TIKA-4058:
------------------------------------

             Summary: Add file extension .rmd160 to tika-mimetypes.xml
                 Key: TIKA-4058
                 URL: https://issues.apache.org/jira/browse/TIKA-4058
             Project: Tika
          Issue Type: Sub-task
            Reporter: Gregory Lepore
         Attachments: WW-2.2_0.darwin_19.noarch.tbz2.rmd160, WW-2.2_0.darwin_20.noarch.tbz2.rmd160, WW-2.2_0.darwin_21.noarch.tbz2.rmd160, xpr-1.0.5_0.darwin_17.x86_64.tbz2.rmd160

The Common Crawl dataset contains thousands of hash files generated per the Ripemd 160 hashing algorithm ([http://justsolve.archiveteam.org/wiki/RIPEMD-160).] These files are 512 bytes long, have no magic, but end with a .rmd160 extension.

 

That extension is sufficiently unique to serve as a magic number (where it's used) for these files.
