----------------------------------
Summary: Add magic numbers of Olympus ORF Files
Key: TIKA-2658
URL: https://issues.apache.org/jira/browse/TIKA-2658
Project: Tika
Issue Type: Improvement
Components: detector
Affects Versions: 1.18
Reporter: Selim Dincer
For Olympus Raw Files (.ORF) there aren't any magic numbers specified in the
tika-mimetypes.xml file. When I adjust the xml to look like following it works:
{code:java}
<mime-type type="image/x-raw-olympus">
<_comment>Olympus raw image</_comment>
<magic priority="50">
<match offset="0" type="string" value="\x49\x49\x52\x4F"/>
</magic>
<glob pattern="*.orf"/>
</mime-type>
{code}
I tested this with files from my Olympus E-PL7, my Olympus E-M5 and some
Olympus E-M1 Mark II raw files I found on the internet (the most recent
camera). The content type changes from octet stream to image/x-raw-olympus as
expected.
