Description

Tika now detects 7-zip archive as application/octect-stream.
Adding this fragment in tika-mimetypes.xml registry Tika mime magic detector will correctly recognize 7z files:

<mime-type type="application/x-7z-compressed">
<acronym>7zip</acronym>
<_comment>7-zip archive</_comment>
<magic priority="50">
<!-- Magic: '7', 'z', 0xBC, 0xAF, 0x27, 0x1C -->
<match value="7z" type="string" offset="0:1" >
<match value="0xBCAF271C" type="string" offset="2:5" />
</match>
</magic>
<glob pattern="*.7z" />
</mime-type>
