---------------------------------
Summary: ZLIB magic detection support
Key: TIKA-1632
URL: https://issues.apache.org/jira/browse/TIKA-1632
Project: Tika
Issue Type: Improvement
Components: detector
Reporter: Pavel Micka
Priority: Minor
In our environment we encounter many compressed streams, one of them (which is
currently not supported by Tika) is ZLIB. According to my sources and
experience the magics that cover majority of ZLIB archives are these:
<mime-type type="application/zlib">
<_comment>Zlib Compressed Archive</_comment>
<magic priority="45">
<match value="\x78\x01" type="string" offset="0" />
<match value="\x78\x9c" type="string" offset="0" />
<match value="\x78\xda" type="string" offset="0" />
</magic>
</mime-type>
