>                 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
>            Priority: Minor
>             Fix For: 2.0
> 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 Mark II 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.
